Mouse and touch
Conditions and actions to handle either the mouse or touches on touchscreen. By default, conditions related to the mouse will also handle the touches - so that it's easier to handle both in your game. You can disable this behavior if you want to handle them separately in different events. Read more explanations about it.
Actions
Hide the cursor
Hide the cursor.
Show the cursor

De/activate moving the mouse cursor with touches
When activated, any touch made on a touchscreen will also move the mouse cursor. When deactivated, mouse and touch positions will be completely independent.
By default, this is activated so that you can simply use the mouse conditions to also support touchscreens. If you want to have multitouch and differentiate mouse movement and touches, just deactivate it with this action.
