mesh.moveWithCollisions acting strangely

[burbonvagin]

I'm trying get mesh.movewithcollisions working, and I'm not sure why the player sphere is partially intersecting the sphere and the plane. I have some physics in the scene, but turning them off doesn't change the result.

moveWithCollisions does not use the physics. You must use an elipsoide as with the freecamera and enable the collision on objects.

 

see :

=> 4 - Object vs. object collision

thanks! how do you simulate gravity on a character like this? do you just move it down until he intersects a mesh, or is there a better way?

[Dad72]

scene.gravity = new BABYLON.Vector3(0, -0.15, 0);

If use you an elipsoid it receive the gravity

that sounds awesome, but I can't get it to work. https://33fbbfe7efe608e329702f900dfc06fc804016bb.googledrive.com/host/0BzDfAgmFmMswMWdkenBneEFWRVE/mirror_for_junior2/

The cube uses the gravity of the scene, require:

cube.applyGravity = true;

and that the cube does not fall through the ground, require:

plane.checkCollisions = true;

have you read this tutorial here: https://github.com/BabylonJS/Babylon.js/wiki/09-Cameras-collisions

Everything is written on the gravity and collisions

i can easily get it to work with the camera, like the tutorial shows. I can't get it to work with a mesh though. I think I added all the properties here: https://33fbbfe7efe608e329702f900dfc06fc804016bb.googledrive.com/host/0BzDfAgmFmMswMWdkenBneEFWRVE/mirror_for_junior2/

In your Vector3,  you put 0 on the Y position, which has the effect of leaving your object's position or you put it on its height "2" => cube.position = new BABYLON.Vector3(0, 2, 0)

 

if you made -0.1, it'll work.

 

cube.moveWithCollisions (new BABYLON.Vector3 (0,01, -0.1, 0));

thanks

[burbonvagin]

this is a replacement for gravity though, right? because when i turn off gravity it still works.

[Dad72]

I think scene.gravity is for camera, or it may be a bug?

[GameMonetize]

scene.gravity is only for camera collisions

Thanks for the confirmation, this is what seemed to me
