Homing projectile vs multiple targets
-
@Jack8680 Yeah but that takes more behaviours :P need another box container to keep the minimum value, then get the minimum value every loop.
EDIT: actually Jack's idea is more efficient and probably takes same amount of behaviours, and makes me wonder why I did it the way I did in the first place.
-
@bosswave you mentioned you want it to look at a group of spawned objects. Are these objects constantly spawning or do they spawn in once.
-
@SplitMindGaming Doesn't matter. When the missile spawns or the homing logic is triggered, it will look at all objects that currently exist with the tag "target".
-
@Aidan-Oxley We think in different ways when making something like this lol.
-
@bosswave here’s my ghetto way of doing it. It doesn’t use arrays. Very simple logic really. But this only works assuming you already spawned in your objects. You can always just already have the objects spawned in but hidden away far off screen. Then have certain events move that object to scene when you want it. You will notice that this method does work and it will follow the closest square that’s next to it. So go ahead move each square next to the missile and it will follow the closest one. Maybe this can be a temporary approach until you learn arrays and know the ways of master aiden. Use safari to download and open this project.Homing missile.tap

Here’s a video showcasing it follow the closest squareFullSizeRender.mov
-
@SplitMindGaming I think Aidan's reworking his to not use arrays right now lol
-
@Jack8680 yeah he’s about to poop on mine right now just wait for it.
-
@bosswave Don't use the other example, use this one instead: https://go.aws/2zEM8XH
Jack made me realise what I was doing before is really over complicating the problem, this one is way simpler and doesn't even use arrays.It's so funny how you can make something complicated, but then it ends up being dumb because of how simple it can actually be.
-
@SplitMindGaming Haven't looked at yours yet, but I think the best way is something like this:
minDistance = -1; foreach(potentialTarget in tag) { distance = CalculateDistance(self, potentialTarget ); if(minDistance == -1 OR distance < minDistance) { minDistance = distance; target = potentialTarget; } }Or if there's a maximum range, you can just do
minDistance = maxRange; foreach(potentialTarget in tag) { distance = CalculateDistance(self, potentialTarget ); if(distance < minDistance) { minDistance = distance; target = potentialTarget ; } }Too bad having an OR in hyperPad isn't quite the same as in a normal programming language; if you put two ifs next to each other connected to the same group of behaviours, it's possible for them to both be true and run the behaviours underneath twice, so it gets a bit messy.
-
@Aidan-Oxley the thing I notice with yours is that it doesn’t follow the closest square. It only follows and locks on 1 target. It doesn’t redirect. Did u check out my video on how mine behaves?
-
@SplitMindGaming It finds the nearest target ONCE, and chases that one forever. It can be told to redirect whenever you want, just activate the behaviour bundle called "Homing trigger" and it will redirect to the nearest target and then chase that one forever. For example: edit the project and add a timer and connect Homing trigger (with all the behaviours under it) underneath the timer. Don't make the timer too fast or you could lag/freeze the project if you have spawned in lots of targets. 0.5s would be fine.
I did look at yours. I moved the blue and green squares both to the top right of the screen and the missile just stopped and sat there.
-
@Aidan-Oxley yeah I was going to say the same thing. When your missile hits the edge of the screen it just stops there and freezes.
-
@Aidan-Oxley
-
@SplitMindGaming If the object the missile is chasing gets deleted, the missile will stop and have nothing to do. In that case, you would want to add some logic to detect when its target is destroyed, and decide what to do then (e.g trigger homing again and select a new target, or just delete the missile). However if you get the missile to constantly redirect to the nearest target on a timer this shouldn't happen unless all targets are destroyed.
-
@Aidan-Oxley sorry I actually want this to work because it’s something I needed for my game as well. I attached a video of me playing your version and turned on the homing behavior as you said so that it can redirect. But it still doesn’t re direct. What am I doing wrong. Are you able to get urs to redirect? FullSizeRender.mov
-
@SplitMindGaming never mind I activated the homing timer instead. How do you activate the behavior bundle homing trigger?
-
@SplitMindGaming If you activate this behaviour in any way (by connecting it under another behaviour directly, using Behaviour On with it selected, or using Execute behaviour with it selected) the missile will redirect targets ONCE.
If I do this, the missile will redirect to the nearest target every 0.5s:
-
@Aidan-Oxley ahhh I didn’t add the timer. Yes it works flawlessly like that. Thanks
-
@Aidan-Oxley care to be a teacher for a bit. I don’t understand input field or even how to use loop properly in that matter. What does it mean when you put “a” on the input field. What does that represent?
