As well as VR - I want 3D physics in my game. So I thought I'd start slowly and just set my FPSC level up as the static body, before I start adding all the dynamic and kinematic objects for the user to play with.

But as soon as I use Create3DPhysicsStaticBody( ObjID ) the exe crashes.

So as part of my exe initialisation, I create the physics world like thus:

Quote: "//load objects
Create3DPhysicsWorld()
Set3DPhysicsGravity(0,-1,0)

LoadFPSCLevel( "level-1" )"


Then as part of "LoadFPSCLevel()" I load the objects created by FPSC-2-AGK and attempt to set them as 3D Physics Static Bodies, but at that point the exe crashes. As soon as i comment out the 2 physics commands the exe runs. Here's where I load the *.x files and set them as static physics objects:

Quote: "if Lower( Right( filename$, 1 ) )="x"
ObjID = LoadObject( filename$ )
//SetObjectCollisionMode( ObjID, 1 )

Create3DPhysicsStaticBody( ObjID )
SetObjectShapeStaticPolygon( ObjID )

ObjStatic.insert( ObjID )
endif"


Here's my complete FPSC level loading code:



Any help would be appreciated.

Ok - it seems there is a problem with the mesh I'm loading. In the Debug Log i see this:

Quote: "Failed to load object "mesh-6.x" - No meshes remaining in levels.agc at line 117"


Is there anyway of checking if a mesh fails to load? I tried GetObjectExists(), but this returns "1".

Sorted it. If you check for the number of meshes linked to the object, the failing objects return zero, so the following solves it:

Quote: "
if GetObjectNumMeshes( ObjID )>0
Create3DPhysicsStaticBody( ObjID )
SetObjectShapeStaticPolygon( ObjID )
endif"

When call ing Create3DPhysicsStaticBody there is no need to call SetObjectShapeStaticPolygon.
Create3DPhysicsStaticBody by default sets the shape to static polygon.
The coffee is lovely dark and deep,and I have code to write before I sleep.
