It's no worse

It literally doesnt works. You just told it produces green lines on your video card. You had to play with magic numbers to make it work again… which will probably last till the next version update. 

@Aressera Good points all around! This feels like a direction I can get started in.

Thanks everyone,

Yeah, I know SDL2 inside and out. I thought this book was SDL2 ?. I just found the book interesting and some of the things they were talking about at the end. Thought I might pick up some concepts of using SDL differently and abstracting it. I still think I could, but if it's SDL1 t…

Hello,

I'm writing a simple GUI with SDL (1.2).

According to you, what is the best solution ?

For simple GUI's it doesn't matter what you do. If you ever have overlapping GUI elements, then you may want option 1) and let the container work out which element is being hit, based on the …

By far the simplest for small projects is not to bother building incrementally, but instead do a full build each and every time. That is, make a script that simply performs all build steps, one at a time, using hard-coded paths and library names, eg

#!/usr/bin/env sh
set -e -u -x

CCFLAGS="-Wall -g"…

If you know how to rotate points, you can rotate line segments, just by rotating the ends. If you know how to rotate points around the origin, you can rotate cpstest points around arbitrary points, by first subtracting the coordinates of the center of rotation, then rotating around the …

What platform are you running on?

Also, what does the output of the following show for your system?

glxinfo | grep OpenGL

Have you tried a basic SDL window as in the Wiki example?

This looks similar to the issue you are running into:

Can you tell me which line and file you are referring to with if(SDL_JoystickOpen(i) != 1)
SDL_JoystickOpen returns a nullptr when it fails. So change the 1 to nullptr

Please Net-Ninja? Thanks.

Thanks Scienthsine and Zakwayda for the help

I've found another way of doing it, let me explain.

Btw, here is the code

void Entity::update()
{
    if (movCycle <= myVelocity) {
        posX += velocityX * myVelocity;
        posY += velocityY * myVelocity;
        movCycle++…

I solved this error. Here is the solution.

When creating the buffer, create it with the current renderscale. In my case, my render scale was 2.
buffer = SDL_CreateTexture(renderer, SDL_PIXELFORMAT_ARGB8888, SDL_TEXTUREACCESS_TARGET, screenwidth * renderScaleX, screenheight * renderScaleY);

For my final assignment in school, I made a basic multiplayer ray casting game in the browser. The response was so so at the demo held at Case Western in Cleveland, due to it being a silly game. It was programmed in JavaScript, Web Assembly and C. Emscripten was used to output Wasm and glue code…

Thanks Virion will check that out ?

If you're looking for other inspirations, you should look up "RimWorld", and also look at "failed" Dwarf Fortress clones, like "Gnomoria".

Imgui can use image button and translucent background which you may need.

Years ago I think people use CEGUI and MyGUI,you may want to look if interested

Ignore my previous post, I read your question wrong my solution isn't going to help you. When you create an SDL 2 renderer on windows it should default to DirectX 11, I'm not sure what's happening. I did find a post with a similar question

I was just warning you in case you didn't know.

As for tech, conceptually a game is not very complicated. Input is keyboard/joystick/mouse. Output is an animation, a sequence of full-screen images generated at a 20-50 fps. You have a number of different game-parts (intro, high score, instruc…

@Randy Gaul Thank you. I'm going to begin testing stb_image. it seems very promising.

@fleabay It's definitely not the image files. I used two different pngs, plus I tried it with a tif and bmp. I created all files myself, and as a…

I am making a videogame as a learning exercise, using SDL 2.0 as my framework (I can't call it an engine, but I'm using it as my game engine).

I opted to attempt a 2D Turn Based game.

Hey,

Me again, I got some problem with SDL2_mixer on macOs, actually I am thinking about cancelling MacOs version as I found no solution to  play sounds in this platform.

Looks like we will stick with Windows and Linux.
