Trying to stop two triggers from colliding
What do you mean with “prevent”? If you want to only fire it once, put a Do Once Node in front of the Overlap event or Set Active to False or Unbind all Events from Start Overlap.
I want them to do nothing when they hit one another
Could you provide an example?
ok so for the first example you need to know the class of the item to ignore then cast the overlapping object to that class. so you are basically taking the overlapping object and asking is it like this thing im comparing it to, if yes return true, if no return false. pretty east and basic but it has its limitations. you can also use a similar method to this with arrays and loops and do a equal (==) test. but for the basics i just showed a cast in the picture below.
the other option is to create a new object channel so that you can set the collision properties. below ill link a tutorial i found after a quick search. the basics here is that instead of your object being a world static or world dynamic or something, you make it a custom object type. this allows you to go into the collision settings and set the collision response on objects (you can set the object to ignore objects of the custom type). this may seem a bit confusing since i probably didnt explain it well but check out the video linked and it may help.
Thanks I will take a look into your comment has been very helpful
Solved it using Unreal Engine Basics: Collision Channels - YouTube
its really situation dependent but one method would be to use a cast to see if the overlapping actor is of a certain type then have you script run dependent on that. or you could create custom collision channels.
