Trouble with Glut and Opengl

[Sabe Does Things]

Hello! I am currently messing around with opengl and glut and I am trying to clear the window with a grey color. But when its just a black screen.

load "opengl21lib.ring"

load "freeglut.ring"

func display

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)

    glutSwapBuffers()

func init

    glClearColor(0.3, 0.3, 0.3, 0)

    gluOrtho2D(0, 1024, 512, 0)

func main

    glutInit()

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB)

    glutInitWindowSize(1024, 512)

    glutCreateWindow("Ring Raycaster")

    init()

    glutDisplayFunc(:display)

    glutMainLoop()

Hello Sabe

Thanks for the report, Your sample is correct

It was a mistake in RingOpenGL - Fixed in this commit:  Update RingOpenGL - Revise extensions/ringopengl/opengl21/opengl21.cf · ring-lang/ring@b91281c

The error was defining (GLclampf) as Enum instead of Number

To get the update

ringpm update ringopengl21

Then run your sample, and it should work directly (if you are using windows)

Or build the extension after updating the package (if you are using linux/macOS)

WOW! Thank you so much. That was a lot more straight forward to update than I was expecting! I'm really liking Ring so far and I appreciate the help. Also sorry if you see this twice I'm still getting the hang of Google Groups.

Hello so another problem I found was when checking the key event with glutEventKey. I'm trying to do wasd but it doesnt seem to when when I do wasd but it's still getting the code. 

key = glutEventKey()

    switch key

        on 'w' py -= 5

        on 'a' px -= 5

        on 's' py += 5

        on 'd' px += 5

    off

    ? "Key id: " + key

terminal output:

Key id: 119
Key id: 97
Key id: 115
Key id: 100

but when I manually put the code number in it works. I don't mind having to do that but i think you should be able to put the character.

Hello Sabe

Ring comes with Char() and ASCII() functions

? ascii("w")
? char(119)

Output:

119

w

So instead of (switch key) 

Try (switch char(key))
