How do I reset all global variables but one?

Title says all.

I want to reset all the variables, with the exception of one.

Is there any possible way?

Declare a local variable before the loop/actions, set this local var to your global var, reset all globar var then set the one you want to keep with the local var ?

Sorry for this noob question but how do i declare a local variable? on righ click i can only create a global variable .

You don't need to reset all the variables.

Just use the set action and it would change the variable to what you want right before you need to access it.

That's all the advice I can offer.

this game have all the variables reseted, how can i declare a local variable?

Create a global variable, and then drag the global variable into the event where you want the local variable. The icon will change from a world icon to a pin icon when it's done correctly. In the case of my example picture below you can also just right click on the group name and select add>add variable.

Thanks a lot Shirokuma

Also, if you are resetting all variables except one many times throughout your Event Sheet, you can just create a function that does it.
