opengl es and functions - burrows111 - Feb 23, 2010 04:15 PM
Hi all, please help,
am currently in the starting process of coding an opengl es "bowling" game,
i have small but goodish experience in opengl so ES shouldn't prove so hard to get to grips with, and i know 'C' abit but sadly i am not picking up objective c as well as hoped.
simply i am using the template that the SDK provides for an openGLes app, and yes runs fine, but am planning to implement game states . such as paused, main menu , etc.
I am having huge issues trying to get to grips with functions and their calls.
the template runs immediately a bouncing box, so what i am currently trying to do is edit this so that i am switching the state of the game and run a render function accordingly.
Code:
-(void) RenderPerState
{
switch (gameState) {
case 1: //paused
//do this while paused
break;
case 2: //playing
//do this while playing
break;
case 3: //main menu
-(void) render;
break;
case 4: //splash screen
//do this at splashscreen
break;
default:
break;
}
}the case 3 statement all i want to do is run a function that was working but I just simply not calling it right..
suppose all i need ask is, how do i use correct syntax to run the render function
Code:
- (void) render
{
// do my required opengl rendering.
}somebody please point this noob in the right direction.
thanks
