Skeletal Mesh Collision

ChristianB

Hey guys, may sound like a noob question but how do you give skeletal meshes in udk collision so that you cant just walk though them ect also with custom characters? I've been looking around and tried some stuff but all seems to not be working

JamesWild

Most pawns use a cylindercomponent.

ChristianB

yea i setup the collision in UDK using the physics and then selected cylinder as the option but still appears to have lack of collision

JamesWild

Got the source for your pawn class?

Note: if you're trying to build a character in the level editor, do not do that. It's just not how it should be done. Create a UScript class and set it all up in there, before spawning it one way or another.

ChristianB

Yep got my custom uScript classes with the UT_Family and also have the line PhysAsset=PhysicsAsset pointing to my custom physic

JamesWild

I believe the physics asset system applies only to ragdolling characters.

There should be a separate CylinderComponent (it's in the base Pawn class I believe) which is used for collision with the game world.

ChristianB

is it CylinderComponent.SetActorCollision(true, true); ?

ChristianB

here is a picture as an example of my problem to make it easier, my pawn has the collision as you can see

JamesWild

Both pawns need the cylinder component. The one on the right looks like he only has the physics asset, which is only used during ragdolling.

Don't play with the channels, for the most part the defaults are sensible.

ChristianB

So I reverted back, took away the physics mod for ragdoll and also defaulted the collision on the skeletal mesh but as you can see with my dragged in skeletal mesh there is no collision yet on my pawn there is O.o starting to get confusing for me now. Is dragging and dropping a skeletal mesh into a scene the wrong way to go about it if you want it to have the information needed for the collision data?

JamesWild

The collision cylinder is in the pawn class, which references the skeletal mesh. It's not in the skeletal mesh.

If you put two pawns in they would collide with one another.

ChristianB

so in order to have two skeletal meshes collude you need to have both of them scripted in via a pawn class and then spawned via kismet? but what if you want to have a skeletal mesh that runs on a matinee animation?

JamesWild

Typically Matinee is used for cutscenes. Throw a blocking volume around it if you just don't want to be able to walk clean through it. (though blocking volumes can't move)

Alternatively subclass SkeletalMeshActor and put a CylinderComponent in there.
