LeftMouseDown

void LeftMouseDown(string control)
void LeftMouseDown(string control, float x, float y)

Description
Simulates pressing and holding the left mouse button over a specified control.
This does not release the button until a corresponding LeftMouseUp call is made.
Optionally, relative coordinates x and y (values between 0.0 and 1.0) can be provided to press at a specific position within the control's bounding rectangle.
If omitted, the press is performed at the center of the control.

Parameters
- control - Identifier of the UI control.
- x (optional) - Relative horizontal position within the control (0.0 = left, 1.0 = right). Default: 0.5 (center).
- y (optional) - Relative vertical position within the control (0.0 = top, 1.0 = bottom). Default: 0.5 (center).

Returns
- none

Example
void main()
{
    LeftMouseDown("SLIDER_HANDLE");
    // ... move mouse while holding
    LeftMouseUp("SLIDER_HANDLE");

    LeftMouseDown("CANVAS", 0.1, 0.5); // Press at 10% from left, 50% from top
}
