FPS drops

[Leo Messi]

Hello, My friend made binds script but once I switch weapons there will be FPS drops, I don't know why. Here is the code;

function Switch(button,press)

Adding infinity addEventHandlers, to new created functions and not clearing the Switch function block after every execution. That is what causing the lagg. Your friend should be the one posting the code. If he wants to fix his code, he should start with making a flowchart to figure out which steps he has to make to rewrite his code. Because it is extremely unoptimised and should be recreated.
