| Used on | |
| Code | local mat_debugwhite = Material( "models/debug/debugwhite" ); function ENT:Draw() self:DrawModel(); local mat = Matrix(); mat:Translate( self:GetPos() ); mat:Rotate( self:GetAngles() ); mat:Scale( Vector( 1, 1, 1 ) * 64 ); render.SetMaterial( mat_debugwhite ); cam.PushModelMatrix( mat ); mesh.Begin( MATERIAL_TRIANGLES, 1 ); --mesh.Begin( MATERIAL_LINE_LOOP, 3 ); mesh.Position( Vector( 0, 0, 0 ) ); mesh.Normal( Vector( 0, 0, 1 ) ); mesh.TexCoord( 0, 0, 0 ); mesh.Color( 255, 0, 0, 255 ); mesh.AdvanceVertex(); mesh.Position( Vector( 0, 1, 0 ) ); mesh.Normal( Vector( 0, 0, 1 ) ); mesh.TexCoord( 0, 1, 0 ); mesh.Color( 0, 255, 0, 255 ); mesh.AdvanceVertex(); mesh.Position( Vector( 0, 0, 1 ) ); mesh.Normal( Vector( 0, 0, 1 ) ); mesh.TexCoord( 0, 0, 1 ); mesh.Color( 0, 0, 255, 255 ); mesh.AdvanceVertex(); mesh.End(); cam.PopModelMatrix(); end |
| Output | A triangle that rotates with the entity it is being drawn on. |

- If you make a call to a mesh function that results in an error, your view may become quite messed up; things will render wrong, the skybox will go berserk, etc. In this case, you'll need to restart Garry's Mod to return to normal.
- It may be easier to use the cam library functions to position, rotate, and scale your mesh, rather than trying to calculate it yourself.
