Quads experiment....

Here's a little experiment with quads, and with wireframe
on, it seems to be what I expected, but in regular mode it
quads just pops up a little now and then. Please tell
what's wrong!

The reason the code *appears* big is because key consts
are included. The squares image is just 4 by 4 64x64
squares of different color, but just try any image...

	Global QUAD_SIZE = 30
	Graphics3D 640,480
	
	p = CreatePlane()
	c = CreateCamera()
	MoveEntity c, 0,+7,0
	EntityTexture p, LoadTexture("C:\Program Files\Blitz3D\help\commands\3d_examples\media\MossyGround.bmp")
	
	mc# = 0.1
	m = CreateMesh()
	sf = CreateSurface(m)
	EntityTexture m, LoadTexture("Squares.bmp")
	EntityFX m, 16 + 1
	
	For q = 0 To 3
		AddQuad sf, x, y
		x = x + QUAD_SIZE * 1.10
	Next
	
	Repeat

I don't see anything happening when i run this. I get a plane, with a mossy texture. That's all...

yup, and thats what he wants help with, ya twit :P

what i can see without having time to help much is that youve missed a Y coordinate in one of your Addvetices

EntityOrder m,-100 to draw the quad mesh in front of the plane.
Add these two lines below the EntityFX m,16+1

EntityOrder m,-100
MoveEntity m,-70,30,80

Sorry chaps ^_^
