This further increases the effort required to make a mistake when using the library. Note: since many auto-complete engines order underscores after letters alphabetically, any identifiers starting with an underscore will usually appear at the end of the list. Similarly, this could be applied to the macro definitions and function overides in order to coerce users into only using the getter and setter functions. This essentially reduces the likelihood of a team member making a mistake, by increasing the effort required to type out the names of protected global variables. Since getter functions return a copy of the values stored in the global variables, there is no risk of accidentally modifying them, and hence desynchronising their values. windowMinHeight = - 1 function set_min_size ( width, height ) The following example illustrates how such an approach could be applied: global. These global variables could then be accessed in order to obtain the current window size. One method to circumvent this would be to maintain a set of global variables ones that would store the current minimum and maximum size of the window. This is typically due to the low-priority of niche functionality for instance, there exists functions for setting the minimum and maximum size of the game window 1, but (currently) no functions for getting these values back in case they were updated somewhere else in the codebase. Like many libraries, there are gaps in the set of built-in functions provided by GameMaker. Since this feature is undocumented, it wouldn't be wise to depend entirely on any topics discussed throughout this post, in case something changes in the future or there are inconsistencies between target platforms. This post goes into detail about an undocumented feature of GML, originally brought to my attention by Zach Reedy. GameMaker Studio 2 has introduced some major changes to how things are done with relation to rendering and the creation of rooms, and this means that it is not backwards compatible with legacy GameMaker versions except GameMaker: Studio 1.4. Any project created with the 1.4 version of GMS can be imported into GameMaker Studio 2, but it may need some fixing since there have been a number of things that have been completely removed from the IDE and the GameMaker Language (GML).By exploiting an undocumented feature of macros in GameMaker Language (GML), calls to standard library functions can be intercepted in order to help implement missing features. Note however that GameMaker Studio 2 will do its best to import 1.4 projects and create compatibility Scripts for those functions that are no longer relevant, and you should find that projects from 1.4 will still run in GMS2. If you are wanting to import a project from an older version of GameMaker, then you will first have to import it into GameMaker: Studio 1.4, fix any issues, and then export that to be used in GameMaker Studio 2. With GameMaker Studio 2 we wanted to improve certain areas of the render pipeline, the resource tree, and also and the way that the GameMaker Language is structured, but at the same time we didn't want to completely break backwards compatibility. When you import a 1.4 project (from the File > Import menu) into GameMaker Studio 2, you will be presented with a compatibility report, much like the one shown below: This meant that we had to find a compromise solution so that projects made with the previous version of GameMaker Studio (GameMaker Studio 1.4) could still be imported and "just work". This reports the object events that have been changed as well as the compatibility scripts and macros that have been added to enable the project to keep working in GameMaker Studio 2. The scripts created will be held in a folder marked "compatibility", and there may be other scripts outside of this folder for Macros and Global Variables. The Macros script exists because macros are no longer defined in a separate editor, but instead can be defined inline in the script editor (see the Manual for more details), and the global variables scripts are required for some of the compatibility scripts to function correctly. #Game maker studio 2 click to move manual# The compatibility report will be saved in the Notes resource of the resource tree, and we recommend that you check it and open and revise all the scripts that have been created when importing a 1.4 project. In this way you can quickly see what new functions are required to get the same output as well as any workarounds for those functions that have no direct counterpart in GameMaker Studio 2. #Game maker studio 2 click to move manual#.
