trying to understand vertex2f

[abakoboParticipant]

What are the texCoorx Fields for?

[crayon-5cba8d85841c6154830162 inline="true" ]Struct Vertex2f Field position:Vec2f Field texCoord0:Vec2f Field texCoord1:Vec2f Field color:UInt End

1 2 3 4 5 6

I can’t see any difference when calling addVertex (hidden method from Canvas)

AddVertex( x1,y0,1,0 ) AddVertex( x0,y1,0.1,0 ) End

I should go into GL but I’m afraid it’s going to eat me a lot of time…

can we already put a texture on a triangle or quad with canvas’ drawQuad and drawTriangle?

How about making a replica of “DrawImage” instead?
If you have trouble with the 3 vertices, keep 4 vertices.
The 3 + 4 vertices will have the same data however.

Otherwise you can use this instead DrawPrimitives
You would have exactly the same result but send the data arrays instantly.
