motion_set(dir, speed);

参数 描述
dir The new direction.
speed The new speed.`

返回: N/A(无返回值)


This function sets a new direction of movement and a new speed to the instance running the code. Note that this does not add to the instances current speed and direction (for that you would use motion_add) but rather forces it to the new settings.


if irandom(9) = 1 motion_set(random(360), 1 + random(3));

This above code will make the instance change speed and direction at random intervals.
