Quick Question

I looked in the tutorial, but did not find how to do this(not ghostshooter one, as it does not work on my comp): how do i make it so that every few seconds, a sprite will move onto screen, and even if it is not destroyed, another of it come in?

the system object has a "Every X milliseconds" condition you could use, and it also has a "Create object" action.

So you could use those to create a sprite for example every 10000ms and set the coordinates to outside the layout.

The sprite could do something like:

Is sprite outside layout --> Rotate towards object player
