Okay so i have a sprite sheet with over 200 sprites, on that sheet there is a series of sprites to perform a slash animation, the problem is: i do not know how to perform all those animations when a button is pressed such a 'return'.

Here is a segment of my code:

+ Code Snippet

	while ( LoopGDK ( ) )
	{
		if (dbReturnKey())
		{
			if ((dbSpriteFrame ( hero ) < 22) || (dbSpriteFrame ( hero ) > 26))
				dbSetSpriteFrame ( hero, 22 );
			for (int i = 22; i < 27; ++i)
			{
			dbPlaySprite ( hero, 22, 26, 100);
			}
		}
		dbSync ( );
	}

In the "for loop" i was attempting to play all my sprites related to my slash animation but it seems like the "for loop" is ignored because once i release the 'return' key the animation stops.

Any help would be appreciated.

I havent tested this, but it gives off the general idea.

+ Code Snippet

int Returnin;

		if (dbReturnKey())
		{
			Returnin = 1;
		}
	
		if (Returnin == 1)
		{
			if ((dbSpriteFrame ( hero ) < 22) || (dbSpriteFrame ( hero ) > 26))
				dbSetSpriteFrame ( hero, 22 );
			for (int i = 22; i < 27; ++i)
			{
			dbPlaySprite ( hero, 22, 26, 100);
			}

			if (i >= 26)
			{
				Returnin = 0;
			}
		}

I sawwhat you were tying to do and modified it but it did nothing, hers my new code:

+ Code Snippet

		int returnin;
		if (dbReturnKey() && !dbDownKey () && !dbUpKey () && !dbRightKey () && !dbLeftKey ())
		{
			if ((dbSpriteFrame ( hero ) < 22) || (dbSpriteFrame ( hero ) > 26))
				dbSetSpriteFrame ( hero, 22 );
			returnin = 1;
				while (returnin)
				{
					dbPlaySprite ( hero, 22, 26, 100);
					if (dbSpriteFrame ( hero ) == 26)
					{
						returnin = 0;
					}
				}
		}

the only thing this does thos is "dbSetSpriteFrame ( hero, 22 );
" and completely ignored the while loop

What if you try this? (I can't test it without actually creating an animated sprite.)

+ Code Snippet

while ( LoopGDK ( ) )
{
	if (dbReturnKey())
	{
		if ((dbSpriteFrame ( hero ) < 22) || (dbSpriteFrame ( hero ) > 26))
			dbSetSpriteFrame ( hero, 22 );

		while (dbSpriteFrame(hero) < 26)
		{
			dbPlaySprite ( hero, 22, 26, 100);
			dbSync();
		}
	}
	dbSync ( );
}

Here is a little more developed version. The problem with the previous one is that the program won't do anything else until the animation is finished. It's better to set a flag and check every loop if the animation is still playing.

Does any of these work for you?

+ Code Snippet

	bool slashing = false;

	while ( LoopGDK ( ) )
	{
		if (dbReturnKey() && ! slashing)
		{
			slashing = true;
			if ((dbSpriteFrame ( hero ) < 22) || (dbSpriteFrame ( hero ) > 26))
				dbSetSpriteFrame ( hero, 22 );
		}

		if (slashing) {
			if (dbSpriteFrame(hero) < 26) dbPlaySprite ( hero, 22, 26, 100);
			else slashing = false;
		}

		dbSync ( );
	}
