WEBVTT 00:00.350 --> 00:02.690 Welcome to your next quest. 00:02.720 --> 00:09.500 Now, if you're up to this quest, you're going to implement net serialize for our custom effect context. 00:09.530 --> 00:16.670 Now for this one, make a UN 32 so we can accommodate for all of our variables, call it rep bits and 00:16.670 --> 00:20.290 flip bits on it for each variable when loading. 00:20.300 --> 00:29.720 Now make sure to call, serialize bits on rep bits and then check each bit and archive or unarchive 00:29.720 --> 00:35.300 for each variable based on whether that bit has been flipped. 00:35.420 --> 00:43.100 Now make sure you're looking at how net serialize is implemented in gameplay effect types and see if 00:43.100 --> 00:49.220 you can handle this and make any adjustments that you think should be made so that we can serialize 00:49.220 --> 00:51.710 our two new boolean variables. 00:51.800 --> 00:52.970 Now, that's okay. 00:52.970 --> 00:58.370 If you're a little intimidated by this one, I understand if you want to skip it and just do it along 00:58.370 --> 01:02.900 with me, but if you'd like and if you're up to the challenge, give it a try. 01:02.910 --> 01:06.450 So pause the video and conquer this quest now. 01:09.610 --> 01:10.720 Welcome back. 01:11.380 --> 01:14.440 Now here's net serialized for gameplay effect types. 01:14.470 --> 01:22.210 It uses an uint8, but we're going to use a UNT 32 because we plan on accommodating for more than just 01:22.210 --> 01:23.500 eight variables. 01:24.220 --> 01:31.180 So I'm going to go into my aura ability type scope and we're going to start handling things here. 01:31.180 --> 01:40.600 Now first I'll make my you int 32 called rep bits and initialize it to zero and then I need to check 01:40.600 --> 01:42.670 if my archive is saving. 01:42.670 --> 01:49.960 So we're going to say if R dot is saving then we have some bits to flip. 01:49.960 --> 01:57.240 Right now I'm going to go ahead and just take some code from gameplay effect types. 01:57.250 --> 02:05.410 I do want to flip bits for the instigator for the effect causer, the source object, our actors array 02:05.440 --> 02:08.230 our hit results and has world origin. 02:08.470 --> 02:15.880 I'm going to go ahead and just copy all of these if statements and come back over to aura ability types 02:15.880 --> 02:18.490 right in my if statement here and paste them in. 02:18.640 --> 02:26.240 The only difference is I'd like to use the next two bits on my integer rep bits for my two booleans. 02:26.240 --> 02:30.650 And really what we can check is the boolean value of them. 02:30.650 --> 02:36.560 We can see if B is blocked, hit is true or false and b is critical hit. 02:36.590 --> 02:39.350 If they're false, no need to serialize them. 02:39.350 --> 02:40.040 Right. 02:40.040 --> 02:43.340 So let's check first. 02:43.340 --> 02:46.820 I'll check if B is blocked hit. 02:47.700 --> 02:51.180 If it is, we'll flip the bit on rep bits. 02:51.480 --> 02:55.350 Now we're going to use bitwise or equals. 02:55.350 --> 02:58.710 And the last bit we flipped was the sixth one. 02:58.710 --> 03:04.890 So now we're going to flip the seventh, we're going to say one left shift seven just like that. 03:05.040 --> 03:07.080 And we'll do this for the next boolean. 03:07.110 --> 03:10.950 If bee is critical hit. 03:12.690 --> 03:16.170 If so, we'll flip the eighth bit so we'll say rep bits. 03:17.070 --> 03:21.720 Bitwise or equals one left shift eight. 03:22.050 --> 03:24.000 So that's the first step. 03:24.030 --> 03:28.750 Now let's take a look at gameplay effect types after flipping bits. 03:28.770 --> 03:33.510 We call the archive Serialized bits function passing in rep bits. 03:33.510 --> 03:36.300 It's actually passing in the address of rep bits. 03:36.330 --> 03:39.240 Notice serialized bits takes a void pointer. 03:39.270 --> 03:47.820 That means it can take in a pointer to anything we're passing in the pointer to rep bits and the length 03:47.820 --> 03:48.360 of the bits. 03:48.390 --> 03:55.620 Now we're going to be using two more bits, so we need to call this with nine here instead of seven. 03:55.740 --> 04:04.050 So we're going to copy it, come back into Ora ability types and just after the is saving if statement, 04:04.080 --> 04:10.080 we're going to call serialized bits passing in rep bits, the address of it and the length in bits is 04:10.080 --> 04:16.420 going to be two more because we added two more bits that we've flipped on that integer. 04:16.420 --> 04:20.200 So length bits is nine and that's okay if you miss that part. 04:20.200 --> 04:24.940 But that's a very subtle nuance that you need to know about for this to work properly. 04:24.970 --> 04:32.950 Now back in gameplay effect types, we have the checking of the bits for instigator effect causer ability 04:33.550 --> 04:39.610 source object, the actor's array, the hit result the world origin. 04:39.670 --> 04:42.490 Notice that the world origin has an else case. 04:42.520 --> 04:48.730 If that bit has been flipped the sixth one, then it's going to archive world origin. 04:48.730 --> 04:54.550 It's also going to set be has world origin to true, but in the false case it's not going to serialize, 04:54.550 --> 04:57.880 but it is going to set be has world origin to false. 04:57.880 --> 04:58.270 Right. 04:58.270 --> 04:59.170 Interesting. 04:59.170 --> 05:02.440 Well we're going to go ahead and take everything down to here. 05:02.440 --> 05:02.950 Right? 05:02.950 --> 05:10.090 So starting all the way up here, just after serialized bits, all the way down here to the world origin, 05:10.090 --> 05:11.980 We're going to go ahead and copy that. 05:12.010 --> 05:16.000 Come back over here into our function and paste it in. 05:16.000 --> 05:21.220 So that takes care of everything except for our two variables, right? 05:21.220 --> 05:28.780 So we have to check against one left shift seven and one left shift eight as those are the places here 05:28.780 --> 05:30.340 that we care about. 05:30.340 --> 05:31.510 So let's check. 05:31.510 --> 05:39.460 So first we're going to say if and we're going to check rep bits bitwise and and we'll put this in parentheses. 05:39.460 --> 05:42.910 We're going to say one left shift seven. 05:43.920 --> 05:48.690 If that is true, then we know that we serialized. 05:48.720 --> 05:50.100 What did we serialize? 05:50.100 --> 05:51.240 One of our booleans, right? 05:51.240 --> 05:53.700 We serialized B is blocked hit. 05:53.820 --> 06:01.080 So we want to use the archive with the left shift operator and our B is blocked hit. 06:01.080 --> 06:09.780 So we're going to say our left shift B is blocked hit and then we'll do the same thing for B is critical, 06:09.780 --> 06:10.320 hit only. 06:10.320 --> 06:17.880 We're checking against one left shift eight and we're going to use the operator with B is critical hit 06:17.910 --> 06:19.020 like that. 06:19.230 --> 06:19.770 Okay. 06:19.770 --> 06:22.320 So that takes care of almost everything. 06:22.320 --> 06:24.540 Let's check our gameplay effect types. 06:24.540 --> 06:27.150 We'll see that there's just a couple things left. 06:27.180 --> 06:31.710 One is if the archive is loading, we can call add instigator. 06:31.710 --> 06:36.150 We can do that as well and we can also set be out success to true. 06:36.150 --> 06:43.930 So let's just copy those and we'll go back into our net serialize and we'll paste those in. 06:43.930 --> 06:48.430 And now we have successfully implemented net serialize. 06:48.460 --> 06:54.640 We're one step closer to having our own custom gameplay effect context class. 06:54.670 --> 06:57.280 We're almost ready to start learning how to use it. 06:57.280 --> 07:04.180 But there's one more important detail that we haven't quite looked at yet and we'll look at that next. 07:04.300 --> 07:05.350 Excellent job. 07:05.350 --> 07:08.080 And if you did this challenge, I'm very proud of you. 07:08.080 --> 07:13.090 It was a little bit more intimidating with all of this cryptic looking code. 07:13.120 --> 07:18.730 We're messing with bits, so we're getting a little bit lower level, but this is a little more advanced. 07:18.730 --> 07:21.010 So I'm proud of you for sticking through it. 07:21.010 --> 07:23.650 So great job and I'll see you soon.
