This is my project. it works in editor but not in project. I can to move the tower in the editor (Without dragging), but it just randomly goes somewhere in the project mode.

This should probably be in Help with Scripts: I'll report it to be moved for you.

In Sprite2 add one extra line immediately below “when I start as a clone” as below:

when I start as a clone
wait until <not <mouse down?>>

The project may process the mouse down to click the green flag differently in run mode and editor mode.

We wait for the player to release the mouse after clicking the green flag.

I got it to work! Thanks Scratch-Minion
