Graphic problem on MorphOS platform

[papiosaur]

Hello,

I love this game.

i'm porting the game on MorphOS platform (PowerPC), but i have graphic bugs in the menu, in the game some graphics and text are not present.
The Duck move correctly.
Compilation is OK.

It wil be possible to fix this problem for MorphOS platform please?

Thanks

Hello,

Please give me the screenshot of your graphic bugs, have you tried running it on another operating system yet?

Hello,

this is a snapshot of the menu and a small video (sorry for the quality of the video)

Not tested on other platform, sorry i compile only on MorphOS.

Please try running this project for me, if it doesn't work, I think maybe your opengl library has a problem, but I'm not sure, I haven't tried it on your operating system yet

Or can you try use freeglut instead of glut.h, I use it as a replacement and works fine on ubuntu

[papiosaur]

I have changed GL/freeglut.h to GL/glut.h in main.h and LoadModel work fine !

Try loading Lowpoly_Fox model in https://github.com/WHKnightZ/OpenGL-Load-Model/tree/master/Models, to see if it works or not. In the Gravity duck project, the code to draw the images is different with this project.

Work fine too! Just zoom with Mousewheel seems not supported by MorphOS.

Please send me your full source code in Gravity Duck so I can test it and compare it with my Load model project to see if there are any problems.

[WHKnightZ]

By the way, send me a picture of the project LoadModel running on your computer.

[papiosaur]

I have changed nothing in the code.

This is a snapshot of LoadModel on MorphOS:

Maybe an Endian problem about graphic bug on Gravity Duck?

Hello,

i have tried to port CubeSnake and i have a similar problem with 2D textures:

https://www.morphos-storage.net/upload/test/gravityduck/CubeSnake.jpg

i need to deactive the line 60 in main.c of CubeSnake:

glHint(GL_MULTISAMPLE_FILTER_HINT_NV, GL_NICEST);

Maybe is not implemented in TinyGL of MorphOS.

I think the problem come from Library/loadpng.c or lodepng.c

I will try to load PNG picture with SDL2 if it change something, or maybe it a problem of texture...

[WHKnightZ]

Sorry, a few days ago I tested both projects on my computer and didn't see any problem, currently my work at my company is quite busy and I'm using windows, it's not convenient to install your operating system to test, so please try loading PNG images using SDL to see if the problem is there, thank you 😄

[papiosaur]

Ha good news !

the 2 games will work with next TinyGL :-D A beta-tester have tested the 2 ports with it and the games work fine without graphic problem.

I have ported LoadModel on MorphOS and added new features:

You can take the source code of course available in the archive.

Thanks a lot for this nice tool!
