I would like to know if i can delete sprite2 using “clear” or “Hide” or any other block from sprite1.
I am looking to dynamically delete or set some propoerties of 1 sprite from another sprite.
Any suggestions?

Use a broadcast then when the other sprite receives the broadcast event then it can do whatever you want like show or hide. What you cannot do is delete a sprite via a script.

You can set ghost effect to 100 then stop all the sprite's scripts. That essentially deletes it. But yeah, like drmcw said, use a broadcast from sprite 1 to do it.

try this code:

//this is for sprite 1:
broadcast[delete sprite 2 v]

// this is for sprite 2:
when i receive[delete sprite 2 v]
hide
