-The ACSUtils mouse cursor library is very easy to use:+ACSUtils provides a mouse cursor library, which lets you easily add mouse support to any interface in your mod. It is very easy to use:

 ''UpdateCursor()'' reads player input and uses it to move the cursor, while taking many mouse setting cvars into account to make sure the cursor is not affected by first person mouse settings. ''CursorX()'' and ''CursorY()'' return the coordinates in the cursor in the [[HUD_coordinate_system]] (default size is 640x480). ''UpdateCursor()'' reads player input and uses it to move the cursor, while taking many mouse setting cvars into account to make sure the cursor is not affected by first person mouse settings.

 +The cursor library doesn't handle mouse clicks, as ZDoom doesn't provide access to mouse buttons. To read mouse clicks, use [[zdoom>GetPlayerInput]] with ''BT_ATTACK'' (left mouse button) and ''BT_ALTATTACK'' (right mouse button). Better yet, use ACSUtils [[input|GetPlayerInput wrappers]] for simpler input handling that will not register multiple clicks if the player holds a mouse button.
 +
 +To check if a button is clicked on screen, check that the cursor is inside the button's rectangle and was clicked.
