macros

so im creating a custom camera, will it constantly create cameras if i set the creation function to a makro or i shuld just create it with a global variable?

so i have defined functions like draw_set_halign to macros and every time i startup the project i get the red ! dot warning with some message that you can see in the screenshot. if i modify the code, like remove ; then add it again, the red dots dissapear, the game also runs normally without a...

I'm currently starting to develop a game with GMS:2, I come from the old days of GM6-8.1. Before starting my development since I have a heavy C# background I would like to, C#-ify my code-base with some macros. For example, undefined in C#, would translate to null. So, naturally I defined a...

Hello GMC, When using macros I expect that they will be fully expanded before any attempts on actual compilation of the GML code (like separate preprocessor and compilation phases). However I noticed that it doesn't seem to always be the case. For example: Create a new project and in the room...

Hi, I am having this error that I cannot make sense of: I somehow narrowed the error to this line: global.DTBS_NUMBER[3] = DTBS_OTHER_NUM - DTBS_ENEMY_NUM; Or more specifically, the use of macro DTBS_OTHER_NUM. The macro is defined as follows: ... DTBS_OTHER_NUM | (DTBS_ENEMY_NUM+20)...

I tried to make a simple one liner singleton macro #macro IMGUI instance_exists(imgui) ? instance_find(imgui,0) : instance_create_layer(0,0,"Instances",imgui) But for some reason this doesn't work. Do ternary operations not work for macros or does this have something to do with the instance...

I've fallen into this trap quite a few times. If I delete a macro or add a macro once, add the same macro (same name) and then delete the extra, the project file won't compile. Then closing and opening GMS 1.4+ will result in the entire project being cleared out. The content is still in the...

I am working on some scripts for terrain generation, and I have some functions which include arguments for a random chance of one instance changing into another instance. For example: "jen_change_change(obj_dirt, obj_sand, 50)" would turn 50% (about) of the dirt into sand. I was considering the...

Hello programmers, I'm wanting to make my room layers easier for me to see and write (in my code) so I was going to use #macro's for this. But I'm not sure which way would be better. Do you? At first, I was going to do it like this, in the Create event of a control object (where I do all my...

GM Version: GameMaker:Studio 2.1.3 Target Platform: ALL Download: N/A Links: Youtube Video Summary: Keyframes Are a great way to define animations, ranging from camera movements to GUI. However GMS2 does not provide an out of the box system to define them. In this tutorial, I present a way to...

Hi guys, So I've just started getting into using bitwise operations and I'm just experimenting with a grid-based movement system. There are a few things I want to clear up: 1. Defining the bits - I've got them set as macros: 2. Setting flags in the play area Following the bits, these are the...

I'm getting a compile error that is unrelated to the actual code it points to. Here's the error: Here's the script in question: The script is called in the create event of my main controller object. The error didn't show up until I added the following line to the controller's draw GUI...

Hey everyone, I have a quick quiestion about the use of Macro/Constances within entites. I was always told that if you know a variables will not change you should make it constant, stop it being changed by accident & allows programs to alocate apropriate memory space for them. I have read in...

I use to have many configs with their own specific macros values, but now I don't see how to achieve this with gms2

Hi YoYo team and everyone! I would like to know if it was possible to add a #ifdefined or #ifmacro precompile check or another precompile check to check for use within extensions (I'm saying this because I think this is more of an extension development modular feature). #ifextension...

The new macro definition method is super cool, and long wanted. But for now, I can't figure out the way how to change their value depending on the current configuration. In GMS 1.4 for every configuration selected there was a separate Macro editor, so for example I could toggle between the...

I've seen that you can use #macro name value, but I would like to know where I can find this box that is shown in the manual.

Gamemaker is giving me the following error whenever I try to load my game: FATAL ERROR in action number 1 of Create Event for object INIT: Unable to find any instance for object index '1' at gml_Object_INIT_CreateEvent_1 (line 45) - p99.name = "P99"; So, my INIT object handles all of my...

Hello! This will be my first post here, and it's my first time using GML. However, I have studied numerous programming languages at University, and I'm in my junior year. So I have a fairly firm grasp on programming concepts and languages. Right now I am working on my first game, and I want to...
