| Code | local MaterialWhite = CreateMaterial( "WhiteMaterial", "UnlitGeneric", { -- Necessary to assign color by vertex ["$basetexture"] = "color/white", ["$vertexcolor"] = 1, -- Necessary to assign color by vertex ["$vertexalpha"] = 1, -- Necessary to assign alpha to vertex ["$model"] = 1 } ); 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( MaterialWhite ); 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. |
Additional Notes
- You can only specify colors on a vertex by vertex basis if the material that you are rendering with uses the UnlitGeneric shader.
- The material must also have the "$vertexcolor 1" flag to be capable of having colors assigned to vertices
- In order to specify the alpha for a vertex, the material must have the "$vertexalpha 1" flag.
