How do I repeat an an event after Its done?

I want to repeat this whole event but I dont know how to do It.I havent messed with global variables yet and I have a feeling I might have to.

Would system every 2 seconds work for this?

I want the Blockade to be destroyed after the rocks have dropped and then the blockade should spawn after 1,5 when the rocks have fallen and rocks should fall 2s after the blockade has spawned.

You could do this easily with the timer behaviour..

Just create a sprite called "timer", which we'll use for for project-wide timing and give it the timer behaviour..

on start of layout we'll set the timer for 2 seconds..

Replace the time = 2 seconds with an on timer event..

you can restart the timer either in the event itself or in the event that destroys the rock and blockade..

What do you mean by saying Replace the time?

replace that condition with the "on timer" condition..

so remove the condition "time = 2 seconds" add the condition "on timer"
