Can you help me?

Hello, Im working on a project that it is a shooter game,but im trying to fix a bug but I can't.

Here's the code of the sprite that it has a bug

Other sprite's code:

when I receive [ v]
forever
if <touching [mouse pointer v] ?> then 
set [costume v] to [1]
  

else
set [costume v] to [0]
end
end




The sprite that i think it has a bug
when green flag clicked
forever
switch costume to [(costume) v]
end

please help

also this is my first time joining forums so i made some faults

in the switch costume to (costume) it should be the variable costume in the end
and the sprite's costumes are named 1 and 0
thanks for reading

Could you say what you are trying to do, and what actually happens? (And perhaps share the link of the project)
I'd gladly help!

Welcome Generally, it's easier for people to help you with bugs if you share the project rather than just snippets from it.

One possibility is that you're declaring the costume variable as for this sprite only rather than for all sprites?

Scratch dabbling for fun…

Yes, I was thinking that too
when I receive [ v]
forever
if <touching [mouse pointer v] ?> then 
switch costume to [costume1 v]
  

else
switch costume to [costume2 v]
end
end
Maybe this is what you were trying to do

A more efficient method is

forever
switch costume to [costume2 v]
wait until <touching [mouse-pointer v]>
switch costume to [costume1 v]
wait until <not <touching [mouse-pointer v]>>

end
This is because switching costume is giving Scratch work to do even if you switch to the current costume so it's better to only do so when the costume actually changes.
