Hey, I have a slight problem. I'm trying to make a sprite follow the mouse pointer, something I've done dozens of times, but I believe this is the first time on scratch 3. the script is simple, when start pressed, forever, go to mouse pointer. When run, this script causes IMMENSE lag to the game. I used to have a “go to front layer” block in there with the “go to mouse pointer” block, but I took it out thinking it was causing the lag, which it wasn't. I added a “wait 0.1 seconds” block, and the lag cleared up just fine, but the sprites movement was horrible. (also if I remove the script from the game it runs butter smooth) I am using a high-end computer, so I doubt its that, and my internet connection is great. Any ideas of what might be causing this?

not quite sure what may be happening, but you could try

go to x: (mouse x) y: (mouse y)

glide (0) secs to x: (mouse x) y: (mouse y)

Hmmm… I tried both those methods (thanks by the way ) and they all had the same result: extreme lag.

I'm gonna go try and cause the same lag on a project with nothing on it, maybe that'll yield some interesting results…


OK, I could not cause the game to lag. I even dumped a bunch of sprites doing useless random things on stage, and it still ran great.



Here's something interesting… I let the original game run and the lag is only apparent when sprites are changing size or ghost effect, NOT when changing costumes, preforming tasks, etc. how very odd. (the first half of the project so far is all sprites changing size and ghost effect and I never let it get to the part where the sprites were actually preforming tasks)

Could you give me the link?

Hmm… Try the following script.



Hopefully this helped, and bye!

Welp, I tried that script and it still caused the mystery “lag”. (also, I need the sprite to be upright, with your script it is pointing at the mouse pointer and slowly/quickly moving towards it… and when it reaches the mouse pointer it kinda goes nuts and starts wriggling… you know what I mean)

the web link to the project

Are there any of these you can implement to reduce the lag?

Preventing lag in Scratch
There are a multitude of ways to lower the lag in the Scratch program, such as:

using vector graphics
avoiding the use of detailed vector graphics in motion
avoiding the use of cloning
using fewer sprites
spreading out scripts across other sprites
limiting the amount of objects visible at one time
using custom blocks to fit long and similar scripts
