According to New module changes in Go 1.16 blog

The go command now builds packages in module-aware mode by default, even when no go.mod is present. This is a big step toward using modules in all projects.

as suggested in the blog change the value for GO111MODULE to auto go env -w GO111MODULE=auto would fix the issue.

QUESTION

go + SDL + OpenGL + MacOS example = I get INVALID_OPERATION after DrawArrays()

Asked 2020-May-11 at 01:46

SDL version: 2.0.12
OpenGL version: 3.3 INTEL-10.4.14
I had to force the OpenGL version to 3.3 by requesting core profile, the default version I would get otherwise is 1.2

Following this video tutorial http://youtu.be/yxAPS2eyKmA Games with Go, I tried the OpenGL sample code, and it just shows a black window.
It's supposed to render an orange triangle.

I'm getting INVALID_OPERATION after the second-to-last statement gl.DrawArrays(gl.TRIANGLES, 0, 3)

Your code never calls glUseProgram which means you attempt to draw without a current program object, which is not valid in core profile OpenGL.

QUESTION

SDL2 only returns first registered UserEvent

Asked 2019-Aug-05 at 05:59

I register three events via SDL_RegisterEvents. However, SDL_PollEvent() only returns events of the first type and swallows the others.

This is my code (it's Go, but I don't think that's relevant here):

It only is because of go binding, specifically the line https://github.com/veandco/go-sdl2/blob/24851c1f2d98dcac2a68223a24e6f799fc921f1e/sdl/events.go#L1035 (type conversion only triggered on SDL_USEREVENT, which matches only with first registered event; anything else is reported as "CommonEvent", losing all extra data you may have passed) . You probably should report a bug to developer of said binding.

go-sdl2 not clearing window surface after first run

Asked 2018-Mar-29 at 13:59

I just started going through the SDL tutorial lessons at http://lazyfoo.net/tutorials/SDL/index.php and am working on the first lesson (Lesson 01). I am hand-translating the C/C++ code to Go using the github.com/veandco/go-sdl2 library.

This is my code:

Add an event loop and redraw either unconditionally or when asked to by window manager (SDL_WINDOWEVENT). You can't just draw once and expect things to stay on screen, or even ever be visible (e.g. your draw happened before window manager was ready to show your window), especially with compositing window managers.

Vulnerabilities

No vulnerabilities reported

Install go-sdl2

To get the bindings, type: go get -v github.com/veandco/go-sdl2/sdl go get -v github.com/veandco/go-sdl2/img go get -v github.com/veandco/go-sdl2/mix go get -v github.com/veandco/go-sdl2/ttf go get -v github.com/veandco/go-sdl2/gfx. or type this if you use Bash terminal: go get -v github.com/veandco/go-sdl2/{sdl,img,mix,ttf}. Due to go-sdl2 being under active development, a lot of breaking changes are going to happen during v0.x. With versioning system coming to Go soon, we'll make use of semantic versioning to ensure stability in the future.
