After updating game maker to the one with slow performance issues, I rolled back to 1.754. However, there's no option in this so export the game as a standalone executable. If this a unique issue for me? Or has standalone .exe exporting been removed in recent versions? If so, what version should I rollback to?

Hello, I'm attempting to update a project from gm7 to game maker studio. I'm having trouble though, because the function for variable_global_set is not obsolete.

I was using variable_global_set to save and load the state of objects in rooms on the fly. When the player enters a room, each object would generate a unique id based on the room, the type of object, and its x/y coordinate. For example, an object in room 6 with type 1 at (30,62) would have a global variable of "objvar_6_1_30_62". The object would then check if a global variable of this name exists, and if it does, then load the variable (or array) and change its state (so it would load a value from the variable, like its previous hp). If the variable doesn't exist, then the object would create it with a default value. Then, when the room ends, the object will save its state back into the global variable (like saving the hp to it), so that way the next time the player enters the room, the object will have the same hp.

Since the variable_set and variable_get functions are now obsolete, I'm looking for a way to replace them. My only idea right now would be to make every object persistent, and simply deactivate them when they're not in the right room. Then, if the player enters a room for the 2nd...* time, then the object would activate and destroy the pre-existing one in the room.

However, there has to be a better way than this.

Hey, so I just bought GM studio. I've run into a few crippling bugs so far.

Firstly, whenever I try to save my game as a project, I get the error "The system cannot find the path specified", followed by "An error occured while saving project"

I also get this error when I try compiling one of my games. It always happens right after the compiler is done converting the sound files to .OGG.

Error : Exception : System.ArgumentOutOfRangeException: startIndex cannot be larger than length of string.
Parameter name: startIndex

at GMAssetCompiler.Program.Main(String[] _args)

I've installed on two computers and I have the same problem both times. I'm wondering if anyone else has run into this problem, and has any suggestions on what to do. The saving error is universal, but the exception only happens when I try compiling one of my old games (it used to use included files, but I deleted those to see if it would fix the problem. It didn't)

Hey everyone. Hopefully this won't be too hard to answer.

So I want to find the point along a collision line that obj_a collides with obj_b. If there is any function to do this then it would be a huge lifesaver right now.

Currently I'm using a function I wrote to find out where the collision point is, but it involves using a binary search-esque method where I create a dynamic mask that's half the size of the collision line, and then shrink it in half repeatedly until I find the point where it is no longer colliding. The problem is that this has to happen every frame of the game, and it slows down fps significantly.

Edit : Maybe I can use move_contact with a 1x1 pixel mask to do it? Will there be any speed issues in using this?

Editx2 : I've solved this on my own using the move_contact method. I'll keep this topic open though so that people can search for it in the future if they have a similar question.

Hey, so this shouldn't be that hard of a question. I know of two approaches to solve this, but actually making them work is a different issue.

So basically I want to draw a part of a sprite, as defined by the coordinates of a rectangle. If I have a sprite of a landscape, and I define the corners of the drawing rectangle to some points within the landscape, then I want only the portion of the landscape INSIDE of the rectangle to be drawn.

I think that this can be achieved using draw_sprite_part, but that code specifically seems to have problems doing what I want it to do. I think an easier approach might be to use textured primitives to draw a portion of the sprite, but there are issues with that as well, especially when moving the landscape or the drawing rectangle. An added bonus to the textured primitives approach would be the easy ability to change orientation of the sprite by simply flipping coordinates. Anyways, does anyone have any pointers or solutions for me?

(I think I actually figured out how to do this a couple of years ago when making a signature making program, but somehow my files got corrupted and I can't get the source anymore.)
