Hi,@Cedric answer:
@MackeyK24 On aside, do you know how to detect collisions between a kinematic character controller and a rigid body? The normal methods don’t seem to be doing for me via:
export const setupContactPairResultCallback = (Ammo) => {
const cbContactPairResult = new Ammo.ConcreteContactResultCallback()
//@ts-ignore
cbContactPairResult.hasContact = false
/*
for each contact point search:
cbContactPairResult = callback object (results) for contactPairTest
addSingleResult = metho…
I’m trying to create a controller on my side referring to
Hi,
i am trying to get the Ammo KinematicCharacterController to work with my Babylon Project.
I must do something wrong, because the KinematicCharacterController does not collide with other meshes in my scene. Here is a example where it should collide with the ground mesh: Ammo Kinematic Character Test
Any idea what i missed?
Regards
Stefan
My first question is What controllerK.setUseGhostSweepTest(false) do because according to one post should be set to true but in my case when is set to true object fall down ?
Second question actually the mesh is still overhead and i cant turn it when i turn it her position.y is to high .

Hi @Masty88
I think the quaternion components (x,y,z,w) are not in the same order. Once changed it looks better :
Regarding the setUseGhostSweepTest, I have no idea and a simple Google search didn’t bring anything interesting in the first pages.

Thank you it was just this i’m not to strong on quaternion…i post here an interesting thread from three.js forum where there are a lot of information regardig ammo kinematic_
in fact if i have understand well object fall because my ground is not a kinematic object but just a static object so for the moment i will set the to false and when i have time i will test

I think the answers you’re after live here:
