Remove the ";" at the end of each 'if' line =)

Cuz in that case, u tell the if statement to do nothing =D

well I do recommend using ShellExecute, but it looks like you didnot use the right params,and truly i beleive you can pass in NULL for all the params execpt the int dCmdShow, and the filename.So try...

make sure you put it in the right directory

alternatively , you could use

the function closedown is located in main.cpp after all of my other functions have finished and it is only activated if the escape key is pressed as well as in the piece of code above (right down the bottom next to return

Sorry i should have been more specific, i meant where is the void Dead(void) ?

If your trying to close down the program completely , you must call the return from within the while ( LoopGDK() ) loop which will then send you back to void DarkGDK (void) where then i think you should call _CloseDown(); and then your program should exit successfully

isn't the void Dead(void) being declared in the first line...
void Dead(void) *************
{

for ( int i = 1; i < 500; i++ )

dbDeleteSprite ( i );

for ( int i = 1; i < 500; i++ )

dbDeleteImage ( i );
for ( int i = 1; i < 500; i++ )
dbDeleteMusic ( i );
for ( int i = 1; i < 500; i++ )
dbDeleteSound ( i );
dbText (500 , 230, "GAME OVER");
dbSync ( );
dbSync ( );
dbSync ( );
dbSync ( );
dbSync ( );
dbSync ( );
dbSync ( );


ShellExecute(NULL,"open","./load.exe",NULL,NULL,SW_SHOWNORMAL);
_CloseDown();
return;


}

think he's missing a main loop some how...

@How is it Going, you need to put code in code tags , also i think that void dead is in the main loop which would explain the constant opening of load.exe

its working great now but i have one small problem, my game is a 2d space shooter in which the player must destroy asteroids. my problem is that i have an explosion sheet and some code that should work (to make an explosion) but it bloody well dosn't what happens is that every time the missile (the sprite b) hits an asteroid (the sprite i), instead of playing the animation i've loaded it just plays one picture or frame from it every time i shoot an asteroid so basically it cycles through frames every time the asteroid and missile collide here is code and attatched is explosion sheet: (also if u know a way that will delete the bullet for me than please tell me, i've tried dbHideSprite and dbDeleteSprite as well as just repositioning it with dbSprite)

You need to add a check to see if the animation is already playing so it doesnt just start again every time.



Code is for another project i have but you get the point. Sorry for wierd formatting.

but don't i want it to start again every time, the animation is an explosion and i want it to play every time i hit an asteroid with a missile, as it is it just cycles through one frame every time i hit an asteroid. for instance: i hit one asteroid, it plays the first frame of the explosion and then the frame stays there until i hit another asteroid and it plays the second frame and so on and so forth lol this is not what i want to happen i want the whole animation to play every time my bullet/missile hits an asteroid

The catch here is that dbPlaySprite does NOT play the animation from beginning to end. It has to be repeatedly called, every loop, until the animation finishes. With an animated sprite, you can check if the currently displayed frame (dbSpriteFrame) is the last frame of the animation. If yes, you can stop playing the sprite, otherwise call dbPlaySprite again.

The delay value that you can give to the animated sprite helps because you don't need to calculate how many loops a picture has to be displayed before you change to the next picture of the animation (in other words, it does the timing for you), but that's the only help. In other ways the procedure is not much different from displaying several separate images after each other.

By the way, you don't need to recreate the animated sprite at every collision. It's enough to create it once when your sprites and images are initialized.

he saying you need to call dbPlaySprite ONCE every loop until the animation is at the end, then you can stop the call.

e.g.Something like this in you main loop


With this you need to initialize a local boolean var to false (bool bPlayerHit = false

Then when ever you want the animation to play do bPlayerHit = !bPlayerHit OR bPlayerHit = true;

You will need to check what the current animation is and when it reaches the end reset bPlayerHit to false

You should check the return value of dbSpriteFrame. With that code you don't check which frame is displayed, only that the frame index is different from zero - which it will always be.



Remarks: You may need to add a blank frame at the end of the explosion animation and check for 13 instead of 12, because if the animation is stopped when frame 12 is reached, then frame 12 will never be displayed for more than a split second. It will also be necessary to hide or delete the sprite (depending on your game design) when bPlayerHit changes to false.

Also, this may work for one explosion, but if you have several explosions on the screen at the same time, then instead of the one variable bPlayerHit, you will need an array to keep track of the status of each explosion animation, and of course several sprite numbers to display all of them.
