Beginner - Convert a mesh

[degac]

Ok, after some tests I decided to post to ask help!

 

I have made a little sphere with DeleD, exported as .obj file.

I converted it with the tool obj2gmf.exe and I got my .gmf sphere loaded in my program. Everything is ok

 

Now I want to make 'active' its own physic body - I really dont' understand if obj2gmf creates or not the physic body (from my test - with DebugPhysics(True) it is 'red', but present).

 

I replaced my 'sphere.gmf' with 'oildrum.gmf' and everything works as expected.

What I miss?

I need to use some other tools?

 

'Use the Leadwerks Engine module as our base
Framework leadwerks.engine
'Create an OpenGL graphics window 
Graphics 800, 600
'Allows the engine to find files and load files from zip packages 
RegisterAbstractPath AppDir
'Create a world 
If Not CreateWorld() RuntimeError "Failed to create world."
'Create a camera 
cam:TCamera = CreateCamera()
CameraClearColor(cam, Vec4(0, 0, 1, 1))
MoveEntity cam, Vec3(0, 0, - 5)

'create a ligt
light:TLight = CreateDirectionalLight()
RotateEntity(light, Vec3(65, 45, 0))
'Create a render Buffer
buffer:TBuffer = CreateBuffer(800, 600, BUFFER_COLOR | BUFFER_DEPTH | BUFFER_NORMAL)

body:TBody = CreateBodyBox()
SetBodyMass(body, 1)
mesh:TMesh = CreateCube()
EntityParent(mesh, body)
PositionEntity(body, Vec3(0, 2, 0))

body2:TBody = CreateBodyBox()
SetBodyMass(body2, 1)
mesh:TMesh = CreateCube()
EntityParent (mesh, body2)
PositionEntity(body2, Vec3(0.5, 5, 0))
DebugPhysics(True)

ground:TBody = CreateBodyBox(10, 0.1, 10)
groundmesh:TMesh = CreateCube()
ScaleEntity(groundmesh, Vec3(10, 0.1, 10))
EntityParent(groundmesh, ground)
PositionEntity (ground, Vec3(0, - 1, 0))

Local ball:tmodel=LoadModel("abstract::sphere.gmf")'oildrum.gmf")
PositionEntity ball,vec3(.5,2,0)
'ScaleEntity ball,vec3(0.1,.1,.1) '--> too big?
EntityType ball, 1
SetBodyMass ball, 12

Collisions(1, 1, 1)
EntityType(body, 1)
EntityType(body2, 1)
EntityType(ground, 1)

Thank you

Hi degac,

Generally you make a .phy to go with your object. There is a .phy generator in the SDK /Tools folder called phygen. There are other tools around too including one for 3dsMax.

Ok, thanks, I think I've resolved.

I need to use ConvertMesh.exe and then obj2phy.exe to get the mesh converted and the physic body created.

I just discovered I cant' change 'body scale' in game, but only in the editor.
