Cursor library

The ACSUtils cursor library allows mods to easily add mouse cursor support.

Basic usage

script "Menu" (void) CLIENTSIDE
{
while (true)
{
UpdateCursor();
SetHudSize(640, 480, false);
// Draw cursor at CursorX(), CursorY()
Delay(1);
}
}

UpdateCursor reads player input and moves the cursor. CursorX and CursorY return the current position of the cursor on the screen in HUD coordinate system. The coordinate system is 640×480 by default.

The cursor library does not draw the cursor for you. You can draw it manually using HudMessage or HUD Library, or even keep it invisible.

Advanced features

Getting cursor motion

CursorDeltaX and CursorDeltaY return the difference between the current and the previous cursor positions.

CursorMotionX and CursorMotionY return the difference between the current and the previous cursor positions that would've been there if the cursor was not blocked by screen boundaries.

Setting coordinate system scale

SetCursorArea sets the scale of the coordinate system used by the cursor library. You can even set it to SetCursorArea(1.0, 1.0) and it will work, because the cursor library is fully fixed-point.

Calling SetCursorArea also transforms the cursor's coordinates that it stays in the same place on screen.

Moving the cursor

SetCursorPosition and CenterCursor can be used to move the cursor from ACS.
