1 00:00:00,000 --> 00:00:10,980 alright welcome back in the previous 2 00:00:07,440 --> 00:00:12,660 video we got our characters gun attached 3 00:00:10,980 --> 00:00:15,420 properly to his hand so he's all 4 00:00:12,660 --> 00:00:18,660 animated and looking good and now we 5 00:00:15,420 --> 00:00:21,539 want to animate the enemy character now 6 00:00:18,660 --> 00:00:25,019 here's a quick spoiler this is going to 7 00:00:21,539 --> 00:00:27,330 be a very very quick and easy process 8 00:00:25,019 --> 00:00:29,910 because we're going to reuse some of the 9 00:00:27,330 --> 00:00:32,669 work we've already done we could create 10 00:00:29,910 --> 00:00:35,760 a brand new blend space for our care for 11 00:00:32,669 --> 00:00:38,129 enemy character a brand new enemy and 12 00:00:35,760 --> 00:00:39,960 blueprints specifically for him and we 13 00:00:38,129 --> 00:00:42,300 could assign that exactly the way we did 14 00:00:39,960 --> 00:00:44,100 with the hero what we're going to do 15 00:00:42,300 --> 00:00:46,710 instead is we are going to make a new 16 00:00:44,100 --> 00:00:50,489 blend space to drive between walking and 17 00:00:46,710 --> 00:00:52,350 standing at idle but for our for our 18 00:00:50,489 --> 00:00:54,750 enemy we're just going to reuse the 19 00:00:52,350 --> 00:00:56,550 existing animation blueprint that we all 20 00:00:54,750 --> 00:00:59,250 recruit already used on the hero which 21 00:00:56,550 --> 00:01:01,800 is why we named it character animation 22 00:00:59,250 --> 00:01:04,500 blueprint and not hero animation 23 00:01:01,800 --> 00:01:07,470 blueprint so let's go over to our 24 00:01:04,500 --> 00:01:09,450 animation assets folder and the first 25 00:01:07,470 --> 00:01:13,650 thing we want is to create our blend 26 00:01:09,450 --> 00:01:16,140 space now our enemy character is always 27 00:01:13,650 --> 00:01:17,909 going to turn toward the player he's 28 00:01:16,140 --> 00:01:19,680 always rotated such that he's basically 29 00:01:17,909 --> 00:01:21,659 moving forward and we can see that here 30 00:01:19,680 --> 00:01:25,320 no matter what's going on these guys are 31 00:01:21,659 --> 00:01:27,420 always rotating toward the player so we 32 00:01:25,320 --> 00:01:30,900 don't have to worry about direction 33 00:01:27,420 --> 00:01:33,570 what that means is in terms of a blend 34 00:01:30,900 --> 00:01:35,939 space if you right click and go to 35 00:01:33,570 --> 00:01:38,610 create another blendspace there is a 36 00:01:35,939 --> 00:01:40,920 blend space 1d that we could create 37 00:01:38,610 --> 00:01:43,439 which would be just fine because all we 38 00:01:40,920 --> 00:01:45,720 need is speed however we're not going to 39 00:01:43,439 --> 00:01:47,909 use that and you'll see why here in just 40 00:01:45,720 --> 00:01:49,680 a moment for now just go with me 41 00:01:47,909 --> 00:01:52,229 so we'll create a brand new blend space 42 00:01:49,680 --> 00:01:54,869 and it's going to get just a regular one 43 00:01:52,229 --> 00:01:56,490 not a 1d but a regular blendspace we're 44 00:01:54,869 --> 00:01:58,350 going to base that off of the ue4 45 00:01:56,490 --> 00:02:02,369 mannequin skeleton just as we did before 46 00:01:58,350 --> 00:02:04,810 and we'll call this the enemy blendspace 47 00:02:02,369 --> 00:02:09,610 or enemy blend 48 00:02:04,810 --> 00:02:12,010 fine and light control s and open this 49 00:02:09,610 --> 00:02:13,720 up now this is still going to have the 50 00:02:12,010 --> 00:02:16,390 gun attached to it remember that's just 51 00:02:13,720 --> 00:02:19,720 a preview asset so at any point you can 52 00:02:16,390 --> 00:02:22,599 right-click on the gun socket and choose 53 00:02:19,720 --> 00:02:25,090 remove all attached assets so that takes 54 00:02:22,599 --> 00:02:26,170 away all those preview assets it's still 55 00:02:25,090 --> 00:02:27,970 going to be attached to the game because 56 00:02:26,170 --> 00:02:28,989 we did that in blueprint but it just 57 00:02:27,970 --> 00:02:31,180 gives you that preview 58 00:02:28,989 --> 00:02:32,800 ok so now let's set up the parameters 59 00:02:31,180 --> 00:02:36,760 for this blend space 60 00:02:32,800 --> 00:02:38,350 first off we have our x axis label we 61 00:02:36,760 --> 00:02:41,860 might as well go ahead and set out the 62 00:02:38,350 --> 00:02:44,680 same way so let's call it direction 63 00:02:41,860 --> 00:02:49,180 let's get the same range of negative 180 64 00:02:44,680 --> 00:02:51,670 positive 180 let's give it a y axis 65 00:02:49,180 --> 00:02:53,170 label of speed and we're going to give 66 00:02:51,670 --> 00:02:57,130 this a slightly different ranges will go 67 00:02:53,170 --> 00:02:57,970 between 0 and actually 100 will probably 68 00:02:57,130 --> 00:03:00,370 be just fine 69 00:02:57,970 --> 00:03:02,680 that'll be okay because once we make it 70 00:03:00,370 --> 00:03:04,420 up to 100 centimeters per second above 71 00:03:02,680 --> 00:03:06,580 we wanted to look like he's walking so 72 00:03:04,420 --> 00:03:08,440 that should be alright so let's go ahead 73 00:03:06,580 --> 00:03:10,450 and apply those changes always super 74 00:03:08,440 --> 00:03:12,640 important to do that but the blend space 75 00:03:10,450 --> 00:03:15,310 itself is going to be really different 76 00:03:12,640 --> 00:03:17,560 because we only have two animations we 77 00:03:15,310 --> 00:03:21,609 have idle and we have walk and all we 78 00:03:17,560 --> 00:03:24,280 really care about his speed so we could 79 00:03:21,609 --> 00:03:26,260 if you wanted to you could drag idol to 80 00:03:24,280 --> 00:03:27,910 the center of the graph and if it helps 81 00:03:26,260 --> 00:03:29,170 make things a little clearer by all 82 00:03:27,910 --> 00:03:30,790 means go ahead and do that let's go 83 00:03:29,170 --> 00:03:33,730 ahead and drag an idol at the very 84 00:03:30,790 --> 00:03:36,639 bottom and then a walk at the very top 85 00:03:33,730 --> 00:03:39,519 but no matter what direction the 86 00:03:36,639 --> 00:03:41,709 character thinks it's it's going we want 87 00:03:39,519 --> 00:03:45,220 to always just be walking so we're going 88 00:03:41,709 --> 00:03:51,549 to put walk in the upper corners both 89 00:03:45,220 --> 00:03:52,940 the upper corners what and he's not 90 00:03:51,549 --> 00:03:55,790 walking 91 00:03:52,940 --> 00:03:57,470 and that's because we are not playing so 92 00:03:55,790 --> 00:03:59,240 if we hit play then things seem to work 93 00:03:57,470 --> 00:04:00,770 better and yes again we know this 94 00:03:59,240 --> 00:04:02,240 animation has a little bit of a pop to 95 00:04:00,770 --> 00:04:04,790 it that's okay it's just a temporary 96 00:04:02,240 --> 00:04:07,010 animation anyway 97 00:04:04,790 --> 00:04:08,120 now let's take enemy idol and we're 98 00:04:07,010 --> 00:04:10,370 going to put that down in the lower 99 00:04:08,120 --> 00:04:11,600 corners just for consistency we don't 100 00:04:10,370 --> 00:04:14,180 really need to do that but now we can 101 00:04:11,600 --> 00:04:15,950 test it no matter what direction we are 102 00:04:14,180 --> 00:04:18,049 moving we're always going to look like 103 00:04:15,950 --> 00:04:20,030 we're rotating forward that's fine for 104 00:04:18,049 --> 00:04:22,040 this character because he's always just 105 00:04:20,030 --> 00:04:24,320 going to be moving forward so we can 106 00:04:22,040 --> 00:04:25,580 save this and if at this point you're 107 00:04:24,320 --> 00:04:27,830 thinking in the back your head 108 00:04:25,580 --> 00:04:28,790 why didn't we just use a blend space one 109 00:04:27,830 --> 00:04:31,010 deep 110 00:04:28,790 --> 00:04:33,230 now i'm going to explain it to you we 111 00:04:31,010 --> 00:04:35,330 can now take our character and MBP that 112 00:04:33,230 --> 00:04:39,380 we created earlier right-click on it and 113 00:04:35,330 --> 00:04:41,660 choose create child blueprint class so 114 00:04:39,380 --> 00:04:45,620 this will descend or inherit from 115 00:04:41,660 --> 00:04:47,630 character n MVP and have all of the same 116 00:04:45,620 --> 00:04:52,820 properties all of the same animations 117 00:04:47,630 --> 00:04:55,100 we're going to call it enemy and MVP to 118 00:04:52,820 --> 00:04:57,350 control s and then we'll double-click to 119 00:04:55,100 --> 00:05:00,440 open this up and take a look here we 120 00:04:57,350 --> 00:05:03,980 have the asset override editor open by 121 00:05:00,440 --> 00:05:06,710 default so now we can override animation 122 00:05:03,980 --> 00:05:11,660 assets within this animation blueprint 123 00:05:06,710 --> 00:05:13,790 so let's do that let's expand locomotion 124 00:05:11,660 --> 00:05:16,250 and there is our blend space right there 125 00:05:13,790 --> 00:05:19,340 so it's using the hero blend well 126 00:05:16,250 --> 00:05:20,510 because we made a two-dimensional blend 127 00:05:19,340 --> 00:05:22,340 space for the enemy 128 00:05:20,510 --> 00:05:24,110 it's the same type of blend space so now 129 00:05:22,340 --> 00:05:26,000 it's completely compatible with what we 130 00:05:24,110 --> 00:05:28,040 had here so now check it out 131 00:05:26,000 --> 00:05:30,919 we can just choose the enemy blend 132 00:05:28,040 --> 00:05:32,480 recompile and now we're done 133 00:05:30,919 --> 00:05:35,330 that's it we've already set up the 134 00:05:32,480 --> 00:05:37,250 enemy's animation blueprint we can 135 00:05:35,330 --> 00:05:39,470 change the speed and is it makes it to a 136 00:05:37,250 --> 00:05:41,930 hundred he goes into a walk that's it 137 00:05:39,470 --> 00:05:44,660 that's all we needed to do so compile 138 00:05:41,930 --> 00:05:47,300 save close we can go over to our enemy 139 00:05:44,660 --> 00:05:49,610 characters let's go under blueprints and 140 00:05:47,300 --> 00:05:51,680 let's open up the enemy character will 141 00:05:49,610 --> 00:05:53,720 select his mesh and then under that 142 00:05:51,680 --> 00:05:57,350 NM blueprint generated class property 143 00:05:53,720 --> 00:06:01,669 right here we can set this to the enemy 144 00:05:57,350 --> 00:06:03,449 and MBP compile and save and now if we 145 00:06:01,669 --> 00:06:05,729 play 146 00:06:03,449 --> 00:06:06,900 we're already done they're already 147 00:06:05,729 --> 00:06:08,279 walking there actually walking a little 148 00:06:06,900 --> 00:06:09,599 too quick as you can see their feet 149 00:06:08,279 --> 00:06:11,789 sliding so we'll probably want to slow 150 00:06:09,599 --> 00:06:14,729 them down just a little bit or we could 151 00:06:11,789 --> 00:06:17,189 speed up the walk a little as well in 152 00:06:14,729 --> 00:06:17,759 fact let's do that let's go into let's 153 00:06:17,189 --> 00:06:21,509 escape 154 00:06:17,759 --> 00:06:24,270 let's open up our animation blueprint 155 00:06:21,509 --> 00:06:27,360 let's go actually let's go in her 156 00:06:24,270 --> 00:06:30,719 animation assets and let's find enemy 157 00:06:27,360 --> 00:06:33,210 walk right here and if we take a look 158 00:06:30,719 --> 00:06:36,990 there's a rate scale so we can push this 159 00:06:33,210 --> 00:06:41,550 up to say like 10 1.5 that's too fast 160 00:06:36,990 --> 00:06:43,529 let's do like 1.2 that really makes that 161 00:06:41,550 --> 00:06:45,719 popularly present but again that's okay 162 00:06:43,529 --> 00:06:49,080 this is just for for demo purposes so 163 00:06:45,719 --> 00:06:50,669 now if we play there you go now they're 164 00:06:49,080 --> 00:06:51,990 walking just a little bit faster if you 165 00:06:50,669 --> 00:06:54,419 don't really sliding as much and they 166 00:06:51,990 --> 00:06:57,599 really had this kind of dedicated march 167 00:06:54,419 --> 00:06:59,999 but you see in this way it was very easy 168 00:06:57,599 --> 00:07:03,029 for us to reuse some of our existing 169 00:06:59,999 --> 00:07:04,469 work now also I this video is like 170 00:07:03,029 --> 00:07:05,789 super-short we're technically already 171 00:07:04,469 --> 00:07:07,800 done but I'm gonna do something really 172 00:07:05,789 --> 00:07:09,360 quick because it's been driving me crazy 173 00:07:07,800 --> 00:07:11,759 for the last few videos and I've just 174 00:07:09,360 --> 00:07:14,219 been ignoring it but i'm going to take 175 00:07:11,759 --> 00:07:17,759 the enemy color and change it slightly 176 00:07:14,219 --> 00:07:19,800 it's just a little bit too / driven so 177 00:07:17,759 --> 00:07:25,770 we're going to desaturate that by just a 178 00:07:19,800 --> 00:07:26,610 bit and compile and another pink and 179 00:07:25,770 --> 00:07:28,740 only me 180 00:07:26,610 --> 00:07:30,089 it's pretty funny for them to be pink 181 00:07:28,740 --> 00:07:31,889 you know what I'm going to change their 182 00:07:30,089 --> 00:07:32,550 color entire let's make this let's make 183 00:07:31,889 --> 00:07:41,210 the bad guys 184 00:07:32,550 --> 00:07:43,040 orange orange is a great color 185 00:07:41,210 --> 00:07:45,440 there we are 186 00:07:43,040 --> 00:07:46,580 pick just the right color there we go 187 00:07:45,440 --> 00:07:47,930 this is kind of what I was looking for 188 00:07:46,580 --> 00:07:50,420 right it's just a little bit more of a 189 00:07:47,930 --> 00:07:53,870 desaturation read something it wasn't 190 00:07:50,420 --> 00:07:56,330 quite so brutal on the eyes in our scene 191 00:07:53,870 --> 00:08:00,530 so something kinda like that and compile 192 00:07:56,330 --> 00:08:05,960 and save and if we play there we go 193 00:08:00,530 --> 00:08:08,690 cool so we've now animated both our hero 194 00:08:05,960 --> 00:08:10,430 and our enemy 195 00:08:08,690 --> 00:08:12,200 however there is one last thing you 196 00:08:10,430 --> 00:08:14,210 notice our enemies are just plinking out 197 00:08:12,200 --> 00:08:17,870 of existence so we need to set up the 198 00:08:14,210 --> 00:08:19,640 same behavior that we set up on on our 199 00:08:17,870 --> 00:08:21,950 hero and give them a little bit more 200 00:08:19,640 --> 00:08:24,470 time to play a death animation i 201 00:08:21,950 --> 00:08:25,880 actually forgot to do that well I guess 202 00:08:24,470 --> 00:08:28,460 if the videos / haven't forgotten you 203 00:08:25,880 --> 00:08:31,670 have I so let's go into our event graph 204 00:08:28,460 --> 00:08:35,300 for our enemy character and right here 205 00:08:31,670 --> 00:08:40,010 after is dead we can do the same thing 206 00:08:35,300 --> 00:08:43,190 we did before we can do a delay of three 207 00:08:40,010 --> 00:08:44,180 seconds and this is gonna be kind of 208 00:08:43,190 --> 00:08:46,610 funny so I'm going to show you what 209 00:08:44,180 --> 00:08:49,370 happens if you just play this watch 210 00:08:46,610 --> 00:08:51,290 so if we kill an enemy look at this he 211 00:08:49,370 --> 00:08:52,850 falls down and he keeps chasing us for 212 00:08:51,290 --> 00:08:56,900 like three seconds until he's destroyed 213 00:08:52,850 --> 00:08:59,180 they just keep sliding after us and 214 00:08:56,900 --> 00:09:02,840 that's because technically they're still 215 00:08:59,180 --> 00:09:05,270 chasing us down so let's fix that 216 00:09:02,840 --> 00:09:12,350 there's a special node in order to do 217 00:09:05,270 --> 00:09:15,290 this and it is called detach from 218 00:09:12,350 --> 00:09:17,630 controller pending destroy so what this 219 00:09:15,290 --> 00:09:20,510 does the name is really verbose right 220 00:09:17,630 --> 00:09:22,760 this will detach our enemy character 221 00:09:20,510 --> 00:09:24,290 from it's AI controller knowing that 222 00:09:22,760 --> 00:09:25,400 we're going to be destroying it here in 223 00:09:24,290 --> 00:09:27,710 just a moment 224 00:09:25,400 --> 00:09:30,110 so then the AI controller will no longer 225 00:09:27,710 --> 00:09:31,790 be telling the enemy to chase us 226 00:09:30,110 --> 00:09:34,670 so what we should see is the character 227 00:09:31,790 --> 00:09:36,320 just falls down which is great that's 228 00:09:34,670 --> 00:09:37,820 exactly what we want now there's still a 229 00:09:36,320 --> 00:09:39,500 problem here but it's a really subtle 230 00:09:37,820 --> 00:09:41,990 problem you have to play a lot to test 231 00:09:39,500 --> 00:09:45,050 it out and to make it a little easier to 232 00:09:41,990 --> 00:09:46,340 show off i'm going to grab my spawn 233 00:09:45,050 --> 00:09:48,650 volume real quick 234 00:09:46,340 --> 00:09:51,610 until it's only spawn one enemy at a 235 00:09:48,650 --> 00:09:54,430 time 236 00:09:51,610 --> 00:09:56,589 so should only have the one if I kill 237 00:09:54,430 --> 00:09:57,850 him i still get hung up on him i don't 238 00:09:56,589 --> 00:09:59,589 know if you can really feel that in the 239 00:09:57,850 --> 00:10:01,630 video but there's still a collision 240 00:09:59,589 --> 00:10:03,610 surface there so I knocked him down and 241 00:10:01,630 --> 00:10:06,130 try to run into him and I'm a bumping 242 00:10:03,610 --> 00:10:10,000 into something right there so let's do 243 00:10:06,130 --> 00:10:11,680 this let's say that as soon as the enemy 244 00:10:10,000 --> 00:10:13,120 character dies 245 00:10:11,680 --> 00:10:16,149 we're going to change his capsule 246 00:10:13,120 --> 00:10:18,550 components collision so let's drag this 247 00:10:16,149 --> 00:10:20,680 out drag a reference out to it and then 248 00:10:18,550 --> 00:10:22,990 let's drag a wire off this and just say 249 00:10:20,680 --> 00:10:26,140 collision and see what we have 250 00:10:22,990 --> 00:10:30,970 well we're going to change the response 251 00:10:26,140 --> 00:10:32,380 to a channel so the way collisions work 252 00:10:30,970 --> 00:10:34,510 we actually take a look at the capsule 253 00:10:32,380 --> 00:10:37,060 component and look under collision we 254 00:10:34,510 --> 00:10:41,019 have all kinds of different channels we 255 00:10:37,060 --> 00:10:43,329 can set up we can say I like if i expand 256 00:10:41,019 --> 00:10:47,200 collision presets we can say in response 257 00:10:43,329 --> 00:10:49,480 to static objects we want to overlap or 258 00:10:47,200 --> 00:10:50,980 block or doing overlapping block pause 259 00:10:49,480 --> 00:10:52,240 etc and so forth 260 00:10:50,980 --> 00:10:55,089 we're going to a couple of things here 261 00:10:52,240 --> 00:10:57,490 we are going to dynamically change the 262 00:10:55,089 --> 00:11:03,190 collision behavior the moment the enemy 263 00:10:57,490 --> 00:11:05,589 dies so let's take the its response to 264 00:11:03,190 --> 00:11:08,709 world dynamic which will be things like 265 00:11:05,589 --> 00:11:11,140 our lasers and have it ignore those and 266 00:11:08,709 --> 00:11:13,120 then let's let's do another reference or 267 00:11:11,140 --> 00:11:15,880 we could just do another reference or we 268 00:11:13,120 --> 00:11:17,620 could I do like a rear out node it's 269 00:11:15,880 --> 00:11:21,550 what it's the same thing whichever way 270 00:11:17,620 --> 00:11:26,649 you want to go and let's set collision 271 00:11:21,550 --> 00:11:28,240 and do a set collision response to 272 00:11:26,649 --> 00:11:30,070 channel once again running to the same 273 00:11:28,240 --> 00:11:32,680 thing twice and this time we're going to 274 00:11:30,070 --> 00:11:34,870 take all of our responses to pawns like 275 00:11:32,680 --> 00:11:37,600 the player and set that to ignore as 276 00:11:34,870 --> 00:11:39,100 well so we should no longer be hitting 277 00:11:37,600 --> 00:11:41,440 lasers we should no longer be hitting 278 00:11:39,100 --> 00:11:42,880 the player will clean that up with some 279 00:11:41,440 --> 00:11:43,600 rewrites but when is this going to 280 00:11:42,880 --> 00:11:46,240 happen 281 00:11:43,600 --> 00:11:49,959 well let's have this happen right before 282 00:11:46,240 --> 00:11:51,820 we detach from the controller which will 283 00:11:49,959 --> 00:11:55,610 seem pretty instantaneous between the 284 00:11:51,820 --> 00:11:59,720 two 285 00:11:55,610 --> 00:12:01,339 we'll plug that in and plug that in and 286 00:11:59,720 --> 00:12:02,510 let's clean up our graph a little bit 287 00:12:01,339 --> 00:12:12,170 will have everything going in a nice 288 00:12:02,510 --> 00:12:17,779 clean straight line and there we go so 289 00:12:12,170 --> 00:12:20,149 let's compile save and play and so now 290 00:12:17,779 --> 00:12:21,050 we can shoot our enemy and run right 291 00:12:20,149 --> 00:12:24,320 through it 292 00:12:21,050 --> 00:12:25,970 that's also going to be really useful 293 00:12:24,320 --> 00:12:27,950 where if we get these guys grouped up 294 00:12:25,970 --> 00:12:29,450 our lasers won't stop on that collision 295 00:12:27,950 --> 00:12:30,620 we can start shooting whatever enemy was 296 00:12:29,450 --> 00:12:33,410 right behind him 297 00:12:30,620 --> 00:12:34,459 awesome so the video net did end up 298 00:12:33,410 --> 00:12:36,829 going a little bit longer than i thought 299 00:12:34,459 --> 00:12:39,350 but now we've got our enemies animating 300 00:12:36,829 --> 00:12:41,870 we've got our collision set up properly 301 00:12:39,350 --> 00:12:44,600 when they die really honestly at this 302 00:12:41,870 --> 00:12:46,070 point the game as far as just saying a 303 00:12:44,600 --> 00:12:48,470 pro pro typing something out and getting 304 00:12:46,070 --> 00:12:52,010 it playable the game is essentially done 305 00:12:48,470 --> 00:12:53,690 but we are going to do one last thing to 306 00:12:52,010 --> 00:12:57,410 really finalize it and we're going to 307 00:12:53,690 --> 00:12:59,779 create a UI for a very simple UI using 308 00:12:57,410 --> 00:13:01,490 umg which is what will tackle in the 309 00:12:59,779 --> 00:13:06,880 next video so thanks very much for 310 00:13:01,490 --> 00:13:06,880 joining us
