Cursor

This is a simple library that implements the mouse cursor in ACS.

This library takes into account the player's mouse sensitivity and Y invert settings to make the cursor work the same regardless of the settings.

You should use these functions only in clientside scripts. Serverside usage is not supported.

Serverside cursors are very laggy in mods that use them and can't take the player's settings into account, so we chose to not support serverside cursors.

Widescreen cursors are not supported yet.

Example code

“puke 1” to test.

// puke 1 to test
script 1 (void)
{
    // Do not let the player to rotate the camera while using your cursor.
    SetPlayerProperty(0, true, PROP_TOTALLYFROZEN);
    
    // You can reset cursor settings here.
    CenterCursor();
    SetCursorSpeed(2.0);
    
    while (true)
    {
        // Get mouse input.
        UpdateCursor();
        
        // Draw the cursor.
        HudSetPoint(CursorX(), CursorY());
        HudDrawText(1, "*");
    }
}       

Coordinate system

The cursor's coordinates system matches that of HudMessages with SetHudSize.

Functions

UpdateCursor

void UpdateCursor()

Updates the cursor position using the input from ConsolePlayer (current computer).

CursorX

fixed CursorX()

Returns the cursor's X position.

CursorY

fixed CursorY()

Returns the cursor's Y position.

CenterCursor

void CenterCursor()

Centers the cursor on the screen.

SetCursorPosition

void SetCursorPosition(fixed x, fixed y)

Sets the cursor's position.

SetCursorSpeed

void SetCursorSpeed(fixed speed)

Sets the cursor's current speed multiplier.

Default is 1.0.

SetCursorSpeedX

void SetCursorSpeedX(fixed speed)

Sets the cursor's current X speed multiplier.

Default is 1.0.

SetCursorSpeedY

void SetCursorSpeedY(fixed speed)

Sets the cursor's current Y speed multiplier.

Default is 1.0.

EnableCursorWrap

void EnableCursorWrap(bool enable)

If enabled, the cursor when moved outside the screen, will teleport to the opposite edge of the screen.

SetCursorArea

void SetCursorArea(fixed width, fixed height)

Sets the coordinate system for the cursor. You can use any size from 1.0 to several thousands for any axis. When SetCursorArea is called, the cursor is moved so that its relative position stays the same.

Default is 640×480.

This function does not change the cursor's perceived speed.

CursorDeltaX

fixed CursorDeltaX()

Returns the last change in cursor's X position.

CursorDeltaY

fixed CursorDeltaY()

Returns the last change in cursor's Y position.

SetCursorSpeed

void SetCursorSpeed(fixed speed)

Sets the speed of cursor that multiplies change of cursor coordinates.

Default: 1.0

Also, there are functions only for X Y axis.

SetCursorSpeedX(int speed)

SetCursorSpeedY(int speed)

SetCursorPosition

void CursorSetPosition(fixed x, fixed y)

Sets the position of cursor on the screen.

CursorX/CursorY

fixed CursorX()

fixed CursorY()

Gets the position of cursor on the screen.

UpdateCursor

void CursorUpdate()

Updates the position of acs cursor.
