The brilliant time to start a series of videos, since today we started studying openGL at the university, keep going please 7:35 -ears

[@GetIntoGameDev]

Glad to hear it, good luck with your studies and I hope I can help!

[@GetIntoGameDev]

7:35 - wakey wakey! Nah, I'll tone that down a bit next time.

[@schulenheimer]

tysm for breaking this complex stuff down

[@tanushka3215]

Very helpful, thank you!

[@GetIntoGameDev]

You’re welcome!

[@SkyFly19853]

When there is a video on Python or Ruby. I am right here.

[@leozolotukhin4037]

Thanks for this video! I have a problem with runnig this code. It actualy runs and works, but the pygame window not appears. Maybe you know the solution? Thank you in advance

[@GetIntoGameDev]

Very strange! Is the finished code from the repo working on your system?

[@leozolotukhin4037]

@@GetIntoGameDev yes Code is working, but Window doesn’t appear.

[@sourovdas7883]

Thanks for the video. I got an issue, after running the code for triangle, i've shown this error: "OpenGL.error.NullFunctionError: Attempt to call an undefined function glGenVertexArrays"!! Can you help me out here?

[@GetIntoGameDev]

Hmm, very strange! I've actually not seen that error before. Is this being given by the finished code from the repo too? Which version of Python are you running?

[@sourovdas7883]

@@GetIntoGameDev yes from the finished code from the repo. And python version is 3.10.9. And openGL version is 3.1.6 if that helps.

[@GetIntoGameDev]

@@sourovdas7883 Thanks, which operating system are you running it on? Unfortunately I've not seen this error before but I hope I or someone else can help.

[@sourovdas7883]

@@GetIntoGameDev windows 10. And after searching through on stackoverflow, github, sourceforge i couldn't find a solution to this problem after spending a day just to draw a triangle.

[@arcusma]

So I’m trying to do the pip install from the terminal and I keep getting error messages. Does anyone know how to fix?

[@GetIntoGameDev]

What are the error messages? Did you add Python to the path?

[@uwiwiow7184]

i got lost at some point at the final of the video, when you started using the triangle_mesh, i wasn't able to run the code because i think you modified some part of the code at __init__ in the App class. sorry for my bad english aksjdh

[@GetIntoGameDev]

Is that in the transformed triangle? Was it during the data refresh of uniform section? Happy to help explain if I can

[@uwiwiow7184]

@@GetIntoGameDev during the uniform section, but i already solve it by checking the github end file. thank you

[@undeadpresident]

I appreciate this. What I don't appreciate is youtube's fucking commercials. Maybe you could make a rumble channel too? Would be awesome.

[@GetIntoGameDev]

Thanks, I'll look into it.

[@undeadpresident]

@@GetIntoGameDev cool

[@GetIntoGameDev]

It's up, will. be uploading weekly to test the waters.

​@@GetIntoGameDev Nice. I can watch Rumble on my Roku without getting ads every 3 minutes like when I watch youtube. Ads distract a lot when I'm trying to learn. This video was just what I needed just when I needed it btw. I had just hit a point in the game I'm making where I realized I needed to access the gpu for a shader and was kind of lost for awhile on how to do it. But today I was able to create the colored triangle, and am starting to get some understanding on how opengl works. So thanks again!
