Is there a function or something that when you type a variable name in, and then another one in, it switches the two?
For example: If I type in 'lives' then 'player_health' I change the 'lives' variable name to 'player_health'.

There is no function (THAT I KNOW OF, I am still new to GML) that does this. However, you can follow these steps...

Here is an example using variables "var1" and "var2" as the ones you want to switch:

1. Decide which 2 variables you want to switch (we have already decided on var1 and var2).

2. Create a 3rd variable (we will name it var3).

3. Set the value of "var3" to the current value of "var1."

4. Set the value of "var1" to the current value of "var2."

5. Set the value of "var2" to the current value of "var3."

The way this works is it save the value of var1, then turns var1 ino the second variable (var2), and then turns the second variable(var2) into the variable you saved in the beginning (var3).

Pretty simple, had to figure this out for a project of my own a long time ago...

For global variables:

var a, b;
a=get_string("var to rename","global.var_lol")
if a !="" {b = get_string("Please type in a var to rename " +string(a)+ "","lol")}
if !variable_global_exists("var_lol") {show_message("Variable does not exist");}
else {if variable_global_exists("lol") {if show_question("The Variable " +string(b)+ " Exists#Would you like to overwrite it?") {variable_global_set(b,a)} 
else {show_message("variable not overwritten")}}}

For local variables:

var a, b;
a=get_string("var to rename","var_lol")
if a !="" {b = get_string("Please type in a var to rename " +string(a)+ "","lol")}
if !variable_local_exists("var_lol") {show_message("Variable does not exist");}
else {if variable_local_exists("lol") {if show_question("The Variable " +string(b)+ " Exists#Would you like to overwrite it?") {variable_local_set(b,a)} 
else {show_message("variable not overwritten")}}}

this is just a quick code there is probably a better way to do it

But wouldnt that make you able to change it whilst playing the game? I was thinking of chaning them while coding.
