Picking and box firing doesn't work in the Demos #6

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Build the demos from r32
2. Run the constraints demo
3. Box firing and picking doesn't work

Box fire towards the edge of the screen doesn't fire straight, fires at a weird 
angle

Mouse picking either doesn't work at all or just paints the point2point 
constraint transform onto the object

I can confirm both of those.

I'll double check the box firing as that was definitely working, though the 
aiming of the boxes was a bit rubbish. picking definitely missing though.

The field of view in GetRayTo is wrong. FOV is defined as 40 degrees in the 
projection matrix, so instead of:
public Vector3 GetRayTo(int x, int y)
{
    float top = 1f;
    float bottom = -1f;
    float nearPlane = 1f;
    float tanFov = (top - bottom) * 0.5f / nearPlane;
    float fov = 2.0f * (float)Math.Atan(tanFov);
...

you just need:
public Vector3 GetRayTo(int x, int y)
{
    float fov = MathHelper.ToRadians(40.0f);
...

Picking Constraint has been fixed in demo.
