    Interesting characters (????♀ ♠) appear when sending buffers via TCP

    When I send a buffer package with Game Maker Studio, interesting characters appear at the beginning of the package. (As seen in the picture.) I am sure that the server's coding is not broken because when I code a client with c# and send data from it, the texts go normally. But when I send...

    Asset - Scripts Binary/Buffer Parser

    I've just released a buffer parser asset on the marketplace. It is inspired on the binary parser Node.JS NPM package and is intended to provide an easy way to access multiple data on client/server network buffers. To use it, you must create a "parser template" by chaining multiple parsing...

    SOLVED Sending an image through network

    I've been playing around with GMS 1.4 native networking the last days and I'm doing pretty good, but the challenge I'm facing now is so much more complicated than I've expected. My idea is to send an small image (240 x 135) from the server to the client. As I'm doing my tests on my own computer...

    Is there an asynchronous event for when the app on mobile is minimized?

    I'm testing my project on my Android tablet, and I noticed that if I minimize the project to go to the home screen, then pull it back up again, then gpu_set_texrepeat gets set to false, or at least it appears to. I have 3D elements drawn using the buffer that use textures outside of the 0-1 UV...

    Unions in GML

    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...

    [SOLVED] Sending surface over network

    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 -...

    Handle padding for received data packets?

    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...

    GameMaker Buffer Memory Usage

    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...
