I am having an issue understanding how to get playsprite working when I want to use certain frames for sprite death. frames 1-4 regular animation (loop), 5-8 sprite death(play once through). I am sure that my function is really wrong, but I am just going with what I know as of now.

What i want to happen.
sprites move across screen and animations 1-4 play (loop). This works fine.
a player kills sprite - then play animation 5 - 8, (noloop)
when when sprite resets it goes back to frames 1-4
I could get it to work if I ran a small repeat until loop with a sync(), but that was plain ugly.

Media load section

+ Code Snippet

	//Load pumpkin Images
	for i = 0 to maxPumpkins	
		//SetSpriteGroup(i,pumpsGroup)
		pumpkin[i].enemySpriteNum = CreateSprite(0)
		SetSpriteSize(pumpkin[i].enemySpriteNum,40,40)
		SetSpritePosition(pumpkin[i].enemySpriteNum,-100,-100)
		for j = 1 to 8
			iTmp = LoadImage("pumpkin0"+str(j)+".png")
			AddSpriteAnimationFrame(pumpkin[i].enemySpriteNum,iTmp )
		next j
	next i

sprite hit/score/reset function

function checkForPumkinHit()

//Did player hit the pumpkin?
	for i=1 to maxPumpkins
		if pumpkin[i].enemySpriteNum=hitsprite
			//remove = 1and GetSpriteCurrentFrame(pumpkin[i].enemySpriteNum) = 8
			// PlaySprite( iSpriteIndex, fFps, iLoop, iFromFrame, iToFrame )
			if GetSpritePlaying(pumpkin[i].enemySpriteNum) =1 
				stopSprite(pumpkin[i].enemySpriteNum) 
				SetSpriteFrame(pumpkin[i].enemySpriteNum, 5)
				PlaySprite(pumpkin[i].enemySpriteNum,20,0,5,8)
				//sync()
				log("I am at the playSprite section")
			endif
			//hit
			playSquishSound()
			inc score, 10
			inc levelScore
			if levelScore = 20 then pass = 1
			
			//speed up pumpkins?
			inc squishedPumpkin
			if squishedPumpkin = 5
				inc speedup
				squishedPumpkin=0
			endif
						
			if GetSpritePlaying(pumpkin[i].enemySpriteNum) = 0 // and GetSpriteCurrentFrame(pumpkin[i].enemySpriteNum) = 8
				pumpkin[i].enemyIsActive=0
				pumpkin[i].enemyX=-100
				pumpkin[i].enemyY=Random(100,364)
				pumpkin[i].enemySpeed=Random(1+speedup,5+speedup)
				hitsprite=0
				SetSpritePosition(pumpkin[i].enemySpriteNum,pumpkin[i].enemyX,pumpkin[i].enemyY)

This post has been marked by the post author as the answer.

When you change the animation sequence using playSprite(), you have to first manually specify a starting frame using setSpriteFrame() otherwise it'll run through all frames until it reaches the target range you set.

setSpriteFrame(mySprite, 5)
PlaySprite( mySprite, 20, 0, 5, 8 )

Without setting the frame, you could see your sprite animate from 1 to 8 instead of 5 to 8.

Thanks Phaelax!

I did end of somewhat figuring it out. I don't think it is the most efficient, and I plan on reviewing it further, but I can at least say it is doing what I want it to do currently.

//check for hit function.

function checkForPumkinHit()
	
	//Did player hit the pumpkin?
	for i=1 to maxPumpkins
		if pumpkin[i].enemySpriteNum=hitsprite and pumpkin[i].animateState = 1
			pumpkin[i].animateState = 2
			hitsprite = 0
		endif
			
		if pumpkin[i].animateState = 2 and pumpkin[i].intPass = 0
			play_pumpkins(i)
			playSquishSound()
			inc score, 10
			inc levelScore
			inc squishedPumpkin
		endif

if GetSpriteCurrentFrame(pumpkin[i].enemySpriteNum) = 8 
			pumpkin[i].hideSprite = 1
		endif
		
		if levelScore = 20 then pass = 1
			
		//speed up pumpkins?
		if squishedPumpkin = 5
			inc speedup
			squishedPumpkin=0
		endif
		
		if GetSpriteCurrentFrame(pumpkin[i].enemySpriteNum) > 4 and pumpkin[i].animateState = 2
			log("pumpkin "+str(i)+" current frame:" + str(GetSpriteCurrentFrame(pumpkin[i].enemySpriteNum)))
			log("pumpkin intPass:"+str(pumpkin[i].intPass))
		endif
		
		if  pumpkin[i].hideSprite = 1							
			pumpkin[i].enemyIsActive=0
			pumpkin[i].enemyX=-100
			pumpkin[i].enemyY=Random(100,364)
			pumpkin[i].enemySpeed=Random(1+speedup,5+speedup)
			SetSpriteVisible(pumpkin[i].enemySpriteNum,0)
			SetSpritePosition(pumpkin[i].enemySpriteNum,pumpkin[i].enemyX,pumpkin[i].enemyY)
