Usage

SetMousePosition(x, y);

• x Number. The x coordinate for the mouse to change position to.
• y Number. The y coordinate for the mouse to change position to.

Examples

SetMousePosition(40, 75);

Moves the mouse to coordinates (40, 75) relative to the top-left of the Sphere video display.

const TOP = 50;
const BOTTOM = 160;
const LEFT = 30;
const RIGHT = 200;

var scr_w = GetScreenWidth();
var scr_h = GetScreenHeight();
var white = CreateColor(255, 255, 255);
var f = GetSystemFont();

while (AreKeysLeft()) GetKey();

while (!AreKeysLeft())
{
  f.drawText(0, 0, "Mouse trap! Press any key to quit.");
  
  // Draw bounding box
  Line(LEFT,  TOP,    RIGHT, TOP,    white);
  Line(RIGHT, TOP,    RIGHT, BOTTOM, white);
  Line(RIGHT, BOTTOM, LEFT,  BOTTOM, white);
  Line(LEFT,  BOTTOM, LEFT,  TOP,    white);
  
  // Get mouse location
  var x = GetMouseX();
  var y = GetMouseY();
  
  // Trap mouse!
  if (x < LEFT)   x = LEFT;
  if (x > RIGHT)  x = RIGHT;
  if (y < TOP)    y = TOP;
  if (y > BOTTOM) y = BOTTOM;
  SetMousePosition(x, y);
  
  // Draw mouse location
  Line(0, y, scr_w, y,     white);
  Line(x, 0, x,     scr_h, white);
  
  // Show everything
  FlipScreen();
}

Traps the mouse in a box. The mouse can be moved around, but will not leave the box. Press any key to end the code sample.

Notes

• This function directly corresponds with GetMouseX() and GetMouseY().

• The coordinates to be supplied are relative to the top-left corner of the Sphere video display. If the Sphere graphics driver has a different output scale (e.g. doubled display resolution), the mouse will still be moved according to the desktop resolution scale. Mouse handling is independent of output scaling.
