| Note: While the function described on this page is defined in the Actor class, it only works when called either from a PlayerPawn state, or from one of the StateProvider states handled by PSprite, such as Weapon's Ready/Fire/etc. state sequences or a CustomInventory's Use state sequence. It will have no effect in any other context (such as calling it from a weapon's DoEffect override). If there's a need to achieve a similar effect from a different context, obtain a pointer to the necessary PSprite and modify its fields directly. |
action native void A_OverlayVertexOffset(int layer, int index, double x, double y, int flags = 0)
Usage
Allows for skewing of an overlay by manipulating the vertex directly. Note that modifications of the vertices are always relative to the rotation set by A_OverlayRotate.
Parameters
- int layer
- ID of the layer to modify.
- int index
- Vertices are accessed by an array, and this is the index of the array. Accepted ranges are between [0,3].
- double x
- Offsets the X position of the vertex to the right of the base position if positive.
- double y
- Offsets the Y position of the vertex to the bottom of the base position if positive.
- {[c|int flags}}
- Can be combined with
|:- WOF_ADD - The input adds instead of replaces the current offset, and implies WOF_INTERPOLATE.
- WOF_KEEPX - The 'x' parameter is ignored.
- WOF_KEEPY - The 'y' parameter is ignored.
- WOF_INTERPOLATE - Enables interpolation for the frame called on. For backwards compatibility however, A_OverlayOffset will override the current interpolation setting.
