![]() Since GML is still a dynamic language, if you know that there is a variable of kind on an instance, you can read it from anywhere via direct. However, YoYo Games had made a fairly reasonable decision of not writing a GML->JavaScript compiler (or interpreter) in JS itself, which meant that the interpreter-related functions had to go, variable_ functions included.Īnd so it would have seemed like this functionality is now gone for good. GM:S brought nearly countless additions to GameMaker, including compilation to JS for making HTML5 games with the program. Older versions of GameMaker only ran in interpreted mode on Windows and had a set of variable_local_ and variable_global_ functions, which could be used to variously work with local (instance) and global variables accordingly. Obviously, there are also valid use cases, which is why this post was written. Change the instance's layer variable directly, or use layeraddinstance() Code: object. Add Object1 to the instance layer within Room1 and then just close the room editor again. The sprite needs to have some content of your choice and then be assigned to Object2. This method could be used to create Parallel universes in a game I. Use Your New Extension In Your Game Code Inside the project, create 2 Objects and a Sprite. or reconsider if and why do you need to do that at all. In this video you will make a little program to toggle instances on and off using layers. If you intend to make "a reference" to a variable, you could either wrap it into a 1-element array. names input by user), you might want ot use ds_maps instead. If you intend to add/manipulate entirely arbitrary variables (e.g. Now well play some island instances in this layer so the island instances will appear belodeau player ship because the islands layer is blowing chances layer. If your variables of interest end in numbers ( v1, v2. This is an average-length post covering the aspects of reading/writing variables by their name (as string) in each version of GameMaker.īefore we start, consider the following: do you really need to access variables by names? Since the entire concept is part of reflection, it isn't the fastest, and neither something that you should do often.
