MouseMode.Relative

Description

The cursor is invisible and locked in place, which is what you want for mouse-look style camera control. The mouse’s position stops moving, and its position change becomes the only source of motion - reported in pixel-equivalent units, free of pointer acceleration, and never running out of room at the edge of the screen.

Examples

Mouse-look camera control

MouseMode.Relative hides the cursor and pins it in place, so the mouse can produce motion forever without ever reaching the edge of the screen. Mouse.pos stops moving in this mode, and Mouse.posChange is where all the motion shows up.

Note that the Simulator uses right click for its own flycam, so this is best tried in the Window backend.

static Vec2 lookAngle;
static void MouseLook()
{
	// Capture the mouse for as long as the right button is held
	if      (Input.Key(Key.MouseRight).IsJustActive  ()) Input.MouseMode = MouseMode.Relative;
	else if (Input.Key(Key.MouseRight).IsJustInactive()) Input.MouseMode = MouseMode.Normal;

	if (Input.MouseMode == MouseMode.Relative)
		lookAngle -= Input.Mouse.posChange * 0.1f;
}
