im trying to get my text in the bottom right hand corner but i cant seem to get the cords right

also can somone give me an example of the key gets for the buttons(A,B,Select,Start) the gp32 example pack only has the movment pad

and how would i make a block of text disaperee after a certain amount of time?

 

[slubman]

in Alldraw try this:

GpTextOut(NULL, gpdraw[nflip], cx, cy, g_string, 0x02);

 

[seth]

that causes errors

 

[slubman]

GpTextOut(NULL, &gpdraw[nflip], cx, cy, g_string, 0x02);
i have forgat the "&" :rolleyes:

 

[seth]

when i do that it doesnt draw the text period

 

[slubman]

What do you mean by text period ?????????

 

[seth]

its an expression.

i mean it wont draw the text period(at all)

 

[slubman]

I will study your source code later

 

[slubman]

there is a big problem in your source:
In function GameEngine you enter in an eternal loop with while(1) before drawing anything on screen :rolleyes:
You should call Alldraw from your function game engine, or delete this while from GameEngine and put it into GpMain aroun line AllDraw()

 

[seth]

gpdraw undeclared

 

[slubman]

gpdraw undeclared it's normal, your variable is called gpDraw

Add the prototypes or your functiuns after the includes, and global variables or type your function in order of use for exemple first Init, then AllDraw, follow by GameEngine and finally GpMain

 

[seth]

im still not getting any resualts with it

 

[slubman]

What compiler do you use?

 

[slubman]

#include "gpdef.h"
#include "gpstdlib.h"
#include "gpgraphic.h"
#include "gpmain.h"
#include "gpfont.h"

GPDRAWSURFACE gpDraw[2];
char g_string[256];
int nflip=0;

void Init()
{
	int i;
	GpClockSpeedChange(132000000, 0x24001, 2);
	nflip=1;
	for (i=0; i<2; i++)
	{
  GpLcdSurfaceGet(&gpDraw[i], i);
	}
	GpRectFill(NULL, &gpDraw[nflip], 0, 0, gpDraw[nflip].buf_w, gpDraw[nflip].buf_h, 0xff);
}

void GameEngine()
{
	GpSurfaceFlip(&gpDraw[nflip++]);
	nflip&=0x01;
}

void AllDraw()
{
	int cx, cy=10, cw, ch;
	gp_str_func.strcpy(g_string, "screen center");
	cw=GpTextWidthGet(g_string);
	ch=GpTextHeightGet(g_string);
	cx=(GPC_LCD_WIDTH-cw)/2;
	cy=(GPC_LCD_HEIGHT-cy)/2;
	GpTextOut(NULL, &gpDraw[nflip], cx, cy, g_string, 0x02);
}
void GpMain(void *arg)
{
	Init();
	while (1)
         {
                AllDraw();
        GameEngine();
         }
}

On my computer this work i only test it with geepee 32 not on my GP 32, and using SDT as compiler

 

[seth]

i got it working its just that the text flickers

 

[seth]

and when i try that i always get an error

 

[slubman]

I edit the code check out the nw version!!!
What errors do you get ???

 

[seth]

i dont get any errors its just that the text wont show

 

[seth]

still the text flickers in geepee 32


and besides you still havent anwsered the mina qustion:how do i change the position of the text?

 

[Feeblez]

:rolleyes:
