Function to allow specific quad collision (with or without an image).
In mod/brl.mod/max2d.mod/max2d.bmx on line 1061 (before the Private section), add:
Rem
bbdoc: Check collisions with the given image and layer.
about: The image can be Null (if it is the area of the quad will be checked).
End Rem
Function CollideImageQuad:Object[] (image:TImage, frame:Int, tx0:Float, ty0:Float, tx1:Float, ty1:Float, tx2:Float, ty2:Float, tx3:Float, ty3:Float, collidemask:Int, writemask:Int, id:Object = Null)
Local q:TQuad, pix:TPixmap
'q = CreateQuad(image, 0, x, y, x1, y1, id)
If freequads
q = freequads
freequads = q.link
q.link = Null
Else
q = New TQuad
End If
q.id = id
If image <> Null
pix = image.Lock(frame, True, False)
If AlphaBitsPerPixel[pix.format] q.mask=pix
End If
q.SetCoords(tx0, ty0, tx1, ty1, tx2, ty2, tx3, ty3)
Return CollideQuad(q, collidemask, writemask)
End Function
Would an array, in this case, be worth the slight memory overhead? (for the call, just one array with [x0, y0, x1, y1..])
