Could someone please write a simple example ware there is a green square in the middle of the screen. If you press one of the A,D,S and W keys it moves left right up or down?

I tried to write my own program but for some strange reason glutmainloop wouldn't work so I stuck it somewhare else and now the block only moves when I am moveing or resizing the window

.

Anyone?

I can write you one in cocoa, but you are using Carbon right?

Ok I am just modifying tutorial 2 from NeHe because I don't feel like typing everything to set up GL again, I will email it to you in a sec.

I already posted one... but here goes again...

Code:

#include <stdlib.h>

#if defined(__APPLE_CC__)

#include <GLUT/glut.h>

#else

#include <GL/glut.h>

#endif

void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    // your drawing code goes here

    glutSwapBuffers();

}

void reshape(int width, int height)

{

    glViewport(0, 0, width, height);

}

void idle(void)

{

    glutPostRedisplay();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGBA | GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(640, 480);

    (void)glutCreateWindow("GLUT Program");

    glutDisplayFunc(display);

    glutReshapeFunc(reshape);

    glutIdleFunc(idle);

    glutMainLoop();

    return EXIT_SUCCESS;

}
