Scratch Team, i saw a lag when i put that script of changing (EFFECT) by (Number).
Please guys…
Please tell me why that lagging thing appears.

If a project contains any graphic effect blocks besides ghost and brightness, it may experience glitches such as lag (explained here).

A temporary fix may be to press Ctrl + M or Cmd + M. This switches the mode of the project player.

Or remove the graphic effect blocks from the project. You can keep ghost and brightness.

Only ghost. I have a project that uses the brightness block, and it slows down so much that I can't go further into the video.
