collision detection sizing.

Hello,

I’m working with the collision detection in the physics puzzle and have come across an issue that I know can be resolved, but I’m not sure of the best way to go about it.

The first issue is the collision detection library is storing my object positions in the wrong way. It has y as z and also inverse.

The other issue is that it seems to be set for a 2m x 2m cube. I am able to fix this by going in and adjusting the code in the visual_logic.js file, but I will need to use it on more than just one size, so just changing the cube won’t resolve my issue.

// do not allow empty-sized shapes
size.x = size.x || 0.5;
size.y = size.y || 0.5;
size.z = size.z || 0.5;

if (shape == ‘BOX’) {
var geometry = new Ammo.btBoxShape(new Ammo.btVector3(
size.x * 0.5, size.y * .65, size.z * .9));
} else if (shape == ‘CAPSULE’)

It looks like the Arcade Racing game was able to assign the items and then give each item a unique size.

`// Vehicle contants

var chassisWidth = 1.0;
var chassisHeight = 0.4;
var chassisLength = 3.6;
var massVehicle = 800;`

But there is more going on here than what I need and am not sure on how to set it up for just the ghost collision detection.

Here is the issue I am having. To see the issue, point the move the building to view the right wall (brown wall) and open the doors/window accordion and click the add window button (no need to select a size).

I’m having issues uploading to the website. Will post it when I get it uploaded if it is needed.

Thanks in advance!
