    2D Collision Detection, HELP!

    Hi, can anyone help me? How can I do 2d collision detection when I only have the x and y coords of my objects.

    Thanks.

    To do rectangular collision, you'd need to have the height and width of the objects too.
    All contents of the above post that aren't somebody elses are mine, not the property of some media corporation.
    (Just a heads-up)

    Well...

    You could also hard-code the size of your objects, and use the X and Y as a centerpoint.

    VB Code:
    1. Const ObjectSize = 32

    2.  
    3. Dim ObjectRect as RECT, ObjectX as Long, ObjectY as Long

    4.  
    5. ObjectRect.Left = ObjectX - (ObjectSize \ 2)

    6. ObjectRect.Right = ObjectX + (ObjectSize \ 2)

    7. ObjectRect.Top = ObjectY - (ObjectSize \ 2)

    8. ObjectRect.Bottom = ObjectY + (ObjectSize \ 2)

    Hope this helps...
