GetEntityMaterial

[macklebee]

Why does Script1 work but Script2 does not? It appears that the GetEntityMaterial command only works on items where the material is already Loaded/Painted by code. Or am I just leaving something out, that would allow me to access the material from a loaded entity?

 

Script1:

RegisterAbstractPath("")
Graphics(1024,768)
fw=CreateFramework()
SetGlobalObject("framewerk",fw)
camera=fw.main.camera
camera:SetPositionf(0,0,-2)
light=CreateSpotLight(10)
light:SetRotationf(45,55,0)
light:SetPositionf(5,5,-5)
material=LoadMaterial("abstract::cobblestones.mat")
mesh=CreateCube()
mesh:Paint(material)
ground=CreateCube()
ground:SetScalef(10.0,1.0,10.0)
ground:SetPositionf(0.0,-2.0,0.0)
ground:Paint(mesh.material)
light=CreateDirectionalLight()
light:SetRotationf(45,45,45)
while AppTerminate()==0 do
mesh:Turnf(AppSpeed()*0.5,AppSpeed()*0.5,AppSpeed()*0.5)
fw:Update()
fw:Render()
Flip(0)
end

 

Script2:

RegisterAbstractPath("")
Graphics(1024,768)
fw=CreateFramework()
SetGlobalObject("framewerk",fw)
camera=fw.main.camera
camera:SetPositionf(0,0,-2)
light=CreateSpotLight(10)
light:SetRotationf(45,55,0)
light:SetPositionf(5,5,-5)
mesh=LoadMesh("abstract::oildrum.gmf")

ground=CreateCube()
ground:SetScalef(10.0,1.0,10.0)
ground:SetPositionf(0.0,-2.0,0.0)
ground:Paint(mesh.material)
light=CreateDirectionalLight()
light:SetRotationf(45,45,45)
while AppTerminate()==0 do
mesh:Turnf(AppSpeed()*0.5,AppSpeed()*0.5,AppSpeed()*0.5)
fw:Update()
fw:Render()
Flip(0)
end

I see you are using the property mesh.material. Did you try the functions instead of the properties? GetMaterial() or even GetEntityMaterial() to see if those work?

[macklebee]

yes I had already tried GetEntityMaterial... and GetMaterial is not a function recognized by lua. You are thinking of the GetMaterial() from c++ which is actually GetSurfaceMaterial().

[macklebee]

hmmm but this will work... convoluted but it works:

RegisterAbstractPath("")
Graphics(1024,768)
fw=CreateFramework()
SetGlobalObject("framewerk",fw)
camera=fw.main.camera
camera:SetPositionf(0,0,-2)
light=CreateSpotLight(10)
light:SetRotationf(45,55,0)
light:SetPositionf(5,5,-5)
mesh=LoadMesh("abstract::oildrum.gmf")

ground=CreateCube()
ground:SetScalef(10.0,1.0,10.0)
ground:SetPositionf(0.0,-2.0,0.0)
ground:Paint(GetSurfaceMaterial(GetSurface(mesh,1)))
light=CreateDirectionalLight()
light:SetRotationf(45,45,45)
while AppTerminate()==0 do
mesh:Turnf(AppSpeed()*0.5,AppSpeed()*0.5,AppSpeed()*0.5)
fw:Update()
fw:Render()
Flip(0)
end

 

interesting... thanks for the nudge in the right direction!
