This is some code to be able to collide a line between any two points of given pixel thickness. It should go in Max2D.bmx and could probably be vastly improved, I just bashed it together in the last few minutes to see if it would work.
Function CollideLine:Object[](px1,py1,px2,py2,width,collidemask%,writemask%,id:Object=Null)
Local q:TQuad
q=CreateQuadFromLine(px1,py1,px2,py2,width,id)
Return CollideQuad(q,collidemask,writemask)
End Function
Function CreateQuadFromLine:TQuad(px1,py1,px2,py2,width,id:Object)
Local x0#,y0#,x1#,y1#,tx#,ty#
Local tx0#,ty0#,tx1#,ty1#,tx2#,ty2#,tx3#,ty3#
Local minx#,miny#,maxx#,maxy#
Local q:TQuad
Local f:TImageFrame
Local Angle! = ATan2(py2 - py1,px2 - px1) + 135
tx0 = origin_x+px1 - (Sin(Angle) * Width)
ty0 = origin_y+py1 + (Cos(Angle) * Width)
tx1 = origin_x+px1 + (Cos(Angle) * Width)
ty1 = origin_y+py1 + (Sin(Angle) * Width)
tx2 = origin_x+px2 + (Sin(Angle) * Width)
ty2 = origin_y+py2 - (Cos(Angle) * Width)
tx3 = origin_x+px2 - (Cos(Angle) * Width)
ty3 = origin_y+py2 - (Sin(Angle) * Width)
If freequads
q=freequads
freequads=q.link
Else
q=New TQuad
EndIf
q.link=Null
q.id=id
q.setcoords(tx0,ty0,tx1,ty1,tx2,ty2,tx3,ty3)
Return q
End Function
