buffer

Hi, all. (This is for use with networking, but it might be useful for save data) I have created a BitPacker which allows you to read/write at the bit-level instead of the byte-level to/from buffers. The issue of course was reading and writing data types other than unsigned integers. The...

GM Version: 1.4 Target Platform: ALL Download: N/A Links: N/A Summary: If you try to read beyond the end of a buffer, you will get an error. This is a problem if your game uses buffers for networking, because anyone could maliciously send a buffer that ends unexpectedly, triggering this...

Hi, I've been trying to send an application_surface in a buffer (I'm using a server-client system) and displaying it in the client's game so that he would "see what the server sees" but this doesn't seem to work. It doesn't crash or anything just nothing happens. Here's the code: // Server -...

Hey all, I've run into a weird networking bug. I've got two projects, a client and a server. When I run both on my local computer, or both on an Azure VM, they work fine. However, if I try to run the client on my local machine and the server on a VM, I get the following error as soon as I...

From the GMS2.x docs: async_load[? "buffer"] "buffer": This is the unique "buffer ID" which is generated by the event. A "grow" type buffer, byte aligned to 1, is created to hold the ID should be stored in a variable and used for all further function calls to the buffer in this event. Just like...

Hey guys I've been putting together a multiplayer game with pretty good success. I've encountered "attempting to read from outside buffer, returning 0" errors before, but they're never as ambiguous as the one I'm consistently running into recently. Here it is: FATAL ERROR in action number 1 of...

Hi, I'm noticing when using buffer_delete() I'm not seeing the memory usage come down. For example, if I create a new buffer using buffer_create() the memory increases by let's say 20 MB. When I delete the buffer using buffer_delete() the memory really doesn't move. Then if I repeat this...

I'm trying to save animated gif in GM2. I'm using GM 2.2.5.378 and sometimes I get an error when I use gif_save() function; ___________________________________________ ############################################################################################ FATAL ERROR in action number 1 of...

I'm trying to send a surface to dll and process it in DLL, and after this get this processed image back. I tried send surface as buffer (argument as double) but it's not working. My mean goal is using opencv library in C++. Anyone can help please ?

Like the title says, both players lose connection when I change rooms. Before hand, I'm new to networking and I'm spawning both of them on a setup room to verify if both players are working correctly. However, going to the first level makes the buffers not reach the host and the clients. I've...

Can somebody tell me what I doing wrong in this? before = buffer_create(1024,buffer_fast,1); buffer_poke(before,0,buffer_u8,255); buffer_poke(before,1,buffer_u8,127); buffer_poke(before,2,buffer_u8,63); buffer_poke(before,3,buffer_u8,31); show_debug_message("size...

As the title asks. Why is it necessary to state the size of the buffer when sending a packet? When would you ever use a different value (and what happens if you do? I assume it crops the buffer but then again?)

How do I extend a vertex buffer with additional vertex data after it has been closed with vertex_end, and without removing all existing vertex data in it? Basically what I want is a moving instance drawing its trajectory. Because drawing all segments every step is way too slow, I want to use a...

Hello, is there a way to check if data exists in the position of a buffer you're trying to read from? My code for sending the data has no errors, because my server runs fine for hours, but sometimes it randomly sohws an error "Attempting to read from outside the buffer (line -1)". I think it...

buffer_read argument 1 incorrect type (undefined) expecting a Number (YYGI32) at gml_Object_Server_NetworkingEvent_1 (line 47) - buffer_read(buff, buffer_string) Happens, when I try to read from a buffer, called buff. How to resolve it?

Hello GMC, Looking at the documentation for GM:S 2 I can find functions to calculate checksums of buffers or even compress them. But there doesn't seem to be any native support for buffer encryption and decryption. Looking at the Marketplace there seems to be a few extensions for encryption but...

Hello, i have a little online chat and i'm creating a buffer to send a string (1 byte) and a colour value (4 bytes). Since i have a 4 bytes (buffer_u32) colour value, do i have to use alignment 4 in my buffer? Or can i set it to 1? Because im sending a string in the same buffer, and i think if...

Lately I've been dabbling a bit in multiplayer coding and now I've come to a point where I'd like to have some help. The basic idea is that I generate a random map of 1024x1024 destroyable tiles. Now what I'm wondering is how to transfer this map to the players. The option that makes most sense...

There's no logical problem at all, so it worked perfectly before the 2.2.4 update. It works normally on the PC and some Android phones after the 2.2.4 update. However, a shutdown is inevitable on the home screen if a large(sometimes small) buffer is received after a successful connection is made...

Hi, so I have a java extension( java code: https://pastebin.com/cpwf5LzT ). It has 1 function and the function have 1 argument that is a String called fname. And it returns a String. The function should get the file from the path of fname and if it's an image file, get it as a Bitmap. then I...
