 So you don't know how to collide. Not a problem. Let's say you have a blueprint that activates when you press the E key, but you only wanted to trigger when the player is touching a collider. Well, first in your blueprint under add, give it a box collider, then you can change the size of it to whatever you want. Then under blueprints, click your collider and on the right at the bottom at a component begin overlap and a component and overlap, then drag to cast a third person character, then drag that out to enable input, then get a player controller and make sure it's set to index zero, copy and paste the cast to third person character, then drag that out to disable input, then drag everything together like so, compile, save and now you can see that when we press the E key and we are not touching the box collider, nothing happens. But if we do the same thing inside of collision range, the command will trigger. Hope that helps. And as always, let me have a fantastic day and I'll see you around.
