changing collision box

[Mistah-Skipp]

is there a way to change the character component colliders during runtime? i want to make a crouch that shrink the player hitbox but i cant find a way to get a reference to the colliders length. im using bepu physics within stride 4.2.0.2293 if that helps

I'm not sure how the character component's organized, but if there's a TypedIndex for the character body's shape reference somewhere, you can use that:

ref var directShapeMemoryReference = ref Simulation.Shapes.GetShape<CapsuleShapeOrWhateverItIs>(shapeIndex.Index)

You can also get the raw untyped pointer:

Simulation.Shapes[shapeIndex.Type].GetShapeData(shapeIndex.Index, out void* shapeDataPointer, out int shapeSizeInBytes);

Notably, changing a shape does not have a velocity associated with it; any new collisions will only be resolved retroactively by penetration correction. Same as teleporting a body into penetration.
