I seem to have a problem understanding collision responses with collision components, or something isn’t working the way I would expect, if indeed I do understand.
I can’t get a sphere collision to fire overlap or hit events on a character mesh. I’ve tried literally every permutation on each object in question. The strange thing is, a Projectile’s collision configuration has no issue with this, it will hit the CharacterMesh and give me bones, locations and everything else in the HitResult. But I can’t get the same result with a melee type of collision set up, even though they are set up identically!
I’m thinking there must be something fundamentally different from the collision sphere for the projectile versus the melee collision capsule I’m using, specifically, that there is Movement associated with the Projectile, but the melee collision is not ‘moving’ per say, but is a result of animation.
Is this the fundamental difference? I’d like to get the hit location for the melee weapon, but I can’t get the capsule to collide with the CharacterMesh, no matter how I configure it.
Any ideas on why I can’t get a Hit or Overlap event with the CharacterMesh or what I should be looking for?
For collision to work in UE4, both parties involved must block or overlap each other’s object type (I believe a block-overlap connection results in an overlap.) For instance:
Object A: Type: World Dynamic. Blocks: All.
Object B: Type: World Static. Blocks: All.
These will block each other.
Object C: Type: Vehicle. Blocks: World Dynamic, World Static.
Object D: Type: Pawn: Blocks: All.
These objects will not block each other because Object C does not block Pawn.
Yes, I am enabling Generate Overlap Events on all parties in question. Here are the settings for the parties in question:
CharacterMesh:
Projectile:
Melee:
Now the thing to note, is that I have tried every other combination for the melee to get it to work on the character mesh. The settings on the Melee collision you see here are actually just my current attempt to get a response. The Projectile settings work perfectly, but the melee isn’t working at all. The best I can get for the melee collision is to set its type to WorldStatic and block all but Pawn, then create a collision capsule around the character mesh and test against that, which works, but doesn’t deliver a HitResult.
I’ve tried setting the melee collision to match the projectile collision, but it doesn’t get a response - which is what is so weird…
I already have an alternate system in place to get a hit location, by simply doing a trace, rather than letting the character mesh interact with the melee collision, but I’m just trying to understand why the settings won’t work on their own.
OK - I have the collision set to as it was before - I had to reset the instance settings to the blueprint defaults on the character.
It could very well be that the collision has to be the root component, but I’ll have to look into this more deeply at a later time. For now, doing a short trace to get a bone name will suffice and there is no noticeable difference to the player to do it in this manner.
