How Does 2D Game Lighting Work? | GameMaker

[@glebtsereteli5631]

There is a beefy memory leak issue here - you're creating a new ds_grid every frame without ever destroying it.

[@LeonacYT]

as of today this was not fixed.

[@LeonacYT]

declare a "grid" on CREATE like this: grid = ds_grid_create(2, ds_list_size(points) * 3). On STEP Event: if (!ds_exists(grid, ds_type_grid)) { grid = ds_grid_create(2, ds_list_size(points) * 3); } On POST-DRAW event: if (ds_exists(grid, ds_type_grid)) { ds_grid_destroy(grid) }

@@LeonacYT this dosen`"t work for me : i get : .points(100030, -2147483648) not set before reading it. - grid = ds_grid_create(2, ds_list_size(points) * 3);

This is an amazing video. It teaches you very easily the theory behind making a lighting system. I don't think anyone has ever explained it this in-depth.

How about triangle shaped lighting?

[@frogleap9316]

It works fine, i have a issue with my objects that are not visible in the shadow or when i switch the layer are not visible in the light i need it in revers any help ? I would be grate full, We cast light so if the light is above a obj so the Obj is no longer visible how can we make that work ? I am a total Noob but i want to get my lighting right.

can you help me in game maker I made a 16 by 16 tile set but the pixels were small so I resized and it looked bad

[@jaymesthelionboy7156]

I need help anyone

[@jaymesthelionboy7156]

I'm new to game maker

[@jackp492]

@@jaymesthelionboy7156 you’ll have to start again unfortunately, Have a think about the resolution your game will be played in, and how many tiles will fit on the screen at any given time, and that will be a start of how you scale everything to look, hope that helps

Good video, the content provided does lead to a really decend result. But (as stated) for big rooms with tons of instances/light sources you will have a substantial drop in performance. There is a shader based version that goes in a similar direction that does not have to be a resource drain (please hire this guy). Hopefully one day the other guys from (yes, I am looking at you Unity, Godot or Unreal) won't laugh at our puny light systems and call us brothers in arms with our own instant light system integrated in GameMaker. One day... Great video tutorial in any way, that was a really well crafted explanation of such an advanced topic. kzbin.info/www/bejne/eJnRcpaEhd6ar8k

[@reedrehg]

One day 🤞

[@doublej69]

Thanks for the video. These principles can be applied in shaders that are much more suitable for lightning effects in term of performance.

[@scorpiyon_dev]

Great video as always!

hello, I saw that you are doing well with gamemaker, I also have a problem: I play a game with coins and I save mechanically in room 1 when I enter room 2 where the action of the game takes place, when I return to the end of the game in room 1 it does not save my coins won in the game, this is because it saves in room 1, I don't know how to save only the points and be able to see them in room 1 after the game! I can't save after the game because it stays in room 2, can you help me with a solution? I don't know if you can help me! Thanks in advance! look here what I'm talking about kzbin.info/www/bejne/fZDUqWNvo7Bnbbc
