Touch

If you are working with a touchscreen, your finger becomes the mouse. That means any code blocks that refer to the mouse (such as “when this sprite clicked” or “mouse down?”) will start when your finger touches the screen. This is very similar to the mouse, but there are a few other things you need to consider that are special with touchscreens. Since there is no mouse, trying to use the mouse movement when the mouse is not pressed isn’t possible. It will always be down or there will be no mouse movement at all for a touchscreen. If you have a project that you want to work on using a touchscreen, make sure to try it out on the touchscreen device. Also, on many touchscreens, there is no physical keyboard, so using the “key pressed” blocks won’t work.
