well as the subject tell''s i need help with a pointer...
I thought about using a vector for this to see if it would work but beside''s a couple of other thing''s I don''t know anything about vector''s so I''m not using them.
(Just for reference there is no problem if i declare it like so: CSprite cBulletSprite[BULLETS_MAX]; if i declare BULLETS_MAX, but i want to have BULLETS_MAX read in from a txt file)
the pointer is declared as CSprite *cBulletSprite;
CSprite is just a class with alot of function''s for my Sprite''s.
All of my code work''s right now, but I want to have a config file for how many Bullet''s can be on the screen at once among other thing''s.
So I read all of the data from the config file and it work''s, then I do this: cBulletSprite = new CSprite[BULLETS_MAX];
and it''s all ok, but when I start using the Sprite''s nothing work''s.
I have a boolean var mblVisible in CSprite and when I call fDrawScene() it doesn''t draw the sprite if mblVisible == false
When you hit space it call''s fAddBullet() and it set''s mblVisible to true or false.
*THE PROBLEM* is that the sprite is never Drawn onto the screen
*BULLETS_MOVEMENT is how many pixels the bullet move''s each time*
*BULLETS_TIME_BETWEEN_SHOTS is how many milliseconds to wait before the next bullet can be fired*
*SCREEN_HEIGHT/WIDTH should be easy to understand
*
*SDL_GetTicks() return''s the time (in millisceonds) since the SDL Library was initialized*
*CSprite::mfNotVisible set''s the sprite''s mblVisible to false*
*CSprite::mfVisible set''s the sprite''s mblVisible to true*
*CSprite::mfToggleVisible set''s the sprite''s mblVisible to the opposite of what it is*
*CSprite::mfX/Y Add/Subtract Add''s/Subtract''s To/From the muiX/muiY var''s*
*CSprite::mfGetX/Y return''s the sprite''s muiX/muiY var''s*
*cBulletBase and cPlayerBase hold the frame''s of the sprite''s, and the height (muiH) and width (muiW), among other thing''s*
void fSystem_Shutdown() //Get''s called when the program is closing
{
delete [] cBulletSprite; //Delete the array
SDL_Quit(); //Shutdown SDL
exit(0); //Exit the program
return;
}
inline void fDrawScene()
{
if ((blPaused == false && blDead == false))
{
fDrawBGScroll(); //Inline
//Bullet stuff
for (int bulletNum = 0;bulletNum < (signed)BULLETS_MAX;bulletNum++)
{
if (cBulletSprite[bulletNum].mfGetVisible() == true)
{
cBulletSprite[bulletNum].mfDrawSprite(&cBulletBase, srfScreen);
cBulletSprite[bulletNum].mfXAdd(BULLETS_MOVEMENT);
if (cBulletSprite[bulletNum].mfGetX() > (signed)(SCREEN_WIDTH + cBulletBase.muiW))
{
cBulletSprite[bulletNum].mfNotVisible();
}
}
}
//Player stuff
cPlayerSprite.mfDrawSprite(&cPlayerBase, srfScreen);
}
SDL_Flip(srfScreen); //Update the Screen
}
inline void fAddBullet()
{
if (blFirstBullet == false)
{
if ((SDL_GetTicks() - uiLastShot) >= BULLETS_TIME_BETWEEN_SHOTS)
{
for (int bulletNum = 0;bulletNum < (signed)BULLETS_MAX;bulletNum++)
{
if (cBulletSprite[bulletNum].mfGetVisible() == false)
{
cBulletSprite[bulletNum].mfSetXY(((cPlayerSprite.mfGetX() + cPlayerBase.muiW) + cBulletBase.muiW), (cPlayerSprite.mfGetY() + (cPlayerBase.muiH / 2)));
cBulletSprite[bulletNum].mfVisible();
uiLastShot = SDL_GetTicks();
break;
}
}
}
}
else
{
for (int bulletNum = 0;bulletNum < (signed)BULLETS_MAX;bulletNum++)
{
if (cBulletSprite[bulletNum].mfGetVisible() == false)
{
cBulletSprite[bulletNum].mfSetXY(((cPlayerSprite.mfGetX() + cPlayerBase.muiW) + cBulletBase.muiW), (cPlayerSprite.mfGetY() + (cPlayerBase.muiH / 2)));
cBulletSprite[bulletNum].mfVisible();
uiLastShot = SDL_GetTicks();
break;
}
}
blFirstBullet = false;
}
}
I think that''s all you need to know, but if it isn''t tell me.
Thanks for your help.
