Optimizing Project Performance

This thread discusses techniques for optimizing Scratch projects to improve performance and reduce lag. Here are some key methods:

Avoiding excessive clones of sprites
Mixing scripts efficiently using event blocks
Minimizing backdrop switches when possible
Using local variables over global variables when appropriate
Optimizing nested loops and complex conditionals

Example Optimization

 // Before optimization
 forever
 change [x by 10
 wait [0.01] seconds

 // After optimization
 set [x to (x) + (1000)

The above example shows a common optimization technique for moving a sprite. Instead of increasing the x position slowly in a loop, directly calculating the end position reduces overhead.
