Code:
#include <stdio.h>
#include <math.h>
#include <graphics.h>
#include <conio.h>
#include <dos.h>
Are there any include (header) equivelents to the above in Prizm C?
Thanks.

Well I guess I don't need those headers. I can just make some routines, and use other peoples. Thanks though.

Looks great to me! Have you tried it out on the Prizm to see how it looks? I might mirror the ship/rock to the left side of the icon instead of the right, though, leaving the blank space at right. The letter/number for each add-in is placed at the top-right, so it's better to have that as a blank are of the icon.
Looks great but i agree with purobaz you could use more colors ( but thats just my personal opinion).
And explosions, make sure you have lots of those. They're not too hard to code, really, especially in zero gravity.
And possibly fire, from the ship. Well asteroids is in black and white in its classic form. But I might add color options.
@Kerm: mmhmm it looks good on the Prizm to me. Oh, I didn't think about the numbers/letters because on my Prizm it is past Z so nothing is there. Haha, I might flip it though.

Bump: I am trying to compile for the first time, but the compiler doesn't like this:
Code:
Is there any way I can change this to Prizm acceptable code?
Thanks
Code:
typedef struct
{
int NumPoints;
POINT Point[3];
} SHAPE;
typedef struct
{
POINT Loc; //location
int ViewAngle //Angle facing
POINT Direction; //Direction moving
SHAPE Shape; //Shape of object
Shape Screen //Points it occupies on screen
} OBJECT;
Is there any way I can change this to Prizm acceptable code?
Thanks

You appear to be missing several semicolons.
Indeed. The other thing I don't like is typedef'ing structs instead of just using struct mystructtype xyz;. 
Question:
Code:
I was wondering if this is the best way to code. Making a while loop until they push [Menu]. I am not sure how to structure my code. Can someone help? Thanks.
Code:
void keymenu();
int PRGM_GetKey();
int main(void) {
while(true) {
if(PRGM_GetKey() == KEY_PRGM_MENU) {
keymenu();
//main code
}
}
return 0;
}

I am using KermMartians "fillArea" routine, but the compiler seems to not like it. This is what I have:
Code:
This is what the compiler gave me as error:
Code:
If anyone cares to help that would be great, thanks.
Code:
void fillArea(int x, int y, int width, int height, int color) {
//only use lower two bytes of color
char* VRAM = (char*)0xA8000000;
VRAM += 2*(LCD_WIDTH_PX*y + x);
for(int j=y; j<y+height; j++) {
for(int i=x; i<x+width; i++) {
*(VRAM++) = (color&0x0000FF00)>>8;
*(VRAM++) = (color&0x000000FF);
}
VRAM += 2*(LCD_WIDTH_PX-width);
}
}
This is what the compiler gave me as error:

Like in your previous block of code with the structs, you forgot to put semicolons at the end of some lines. I was asking if you did that again, but you didn't post the code before the fillArea function.
Oh... I fixed it, thanks souvik.
Nevermind, I fix that and many more stuff comes up
Here is my code so far, I know not too advanced.
