![]() ![]() Scripts are pretty great! I love scripts. ![]() This can be used to your advantage, but it's far more likely to trip you up if you don't know it's coming, so as a general rule the return expression is usually only called at the end of a script. It lets you change the variable names etc in gml throughout the entire game. So returns are super useful! But there is one other important thing to keep in mind when using them, and that is that once return is called, the script ends. Change Variable Names Throughout Game Maker This came up in my youtube feed today, and thought you guys might be interested in it. also returns true! But is pretty redundant.) Some GML language elements change the scope and how variables are looked up the most notable one of these is the ' with ' keyword. This command allows you to list or change the values of system variables. (Consequently, if you do "if instance_exists(whatever) = true", and the instance is present, what actually gets evaluated is "if true = true", which. Each system variable has an associated type: integer, real, point, switch. Since instance_exists is checking if an instance of an object exists in the room, it's returning true or false as is, so you don't need to do the expression! It's handy to know. GameMaker: get/set variable value by name This is an average-length post covering the aspects of reading/writing variables by their name (as string) in each version of GameMaker. In this case, one would expect there to be an expression - if x < y then z, for example - which gets evaluated for the if check, but ultimately all expressions do is return true or false.
