iTween Choppy on iPhone

Target Platforms Mobile
1

On the PC, this code works great, it punches the object in a smooth fashion. On the iPhone it is “choppy”. Almost as if it had to skip frames or something. Can someone help me figure out how to make this work just as nicely on the iPhone as it does the PC?

iTween.PunchPosition(SymbolHolder,iTween.Hash(“y”,-80f,“time”,.4f,“delay”,.01f));

What exactly are you punching? Any other code going on at the same time?

SymbolHolder is a GameObject that holds 30+ sub objects (symbols). When the reel stops moving I punch it here to simulate a “reel bounce” just as it stops. This is the only iTween call in the game so far. This itween call and this script is on 5 different SymbolHolder objects.

Here is my code:

else if (reelStopped) //If the reel has stopped lock the symbols into their proper place
		{
			//Make this false so we don't keep locking the symbols into place
			reelStopped = false;
			
			float yDistanceToMove = 0;
			
			for (int x = 0; x < Symbols.Length; x++)
			{
				//If the symbol position is higher than the top reel symbol position and if the symbol is less than
				//the top reel Y position + the height of the symbol
				if (Symbols[x].transform.position.y > ReelTopStartPosition.y)
				{
					if (Symbols[x].transform.position.y < (ReelTopStartPosition.y + symbolHeight))
					{
						//Calculate and store the distance that each symbol needs to be moved to lock into place
						yDistanceToMove = Symbols[x].transform.position.y - ReelTopStartPosition.y;
						break;
					}
				}

			}
			
			//If the reel wasn't prematurely stopped then play stopping sounds
			if (!quickStop)
			//Play stopping sound
			soundManager.PlayReelStopStandard();
			
			//Move symbols into the locked position
			for (int x = 0; x < Symbols.Length; x++)
			{
				Symbols[x].transform.position = new Vector3(Symbols[x].transform.position.x,Symbols[x].transform.position.y - yDistanceToMove,Symbols[x].transform.position.z);

			}
			
			
			//Simulates 'bump' on reel stop
			//If you don't have a delay it will corrupt the symbol ordering
			if (!quickStop)
			iTween.PunchPosition(SymbolHolder,iTween.Hash("y",-80f,"time",.4f,"delay",.01f));

		}

I’m also calling this from FixedUpdate if it matters

What exactly are the 30 objects? Are you Punching the holder or every individual object? From all of the work I’ve done so far with iTween on the iPhone I can say that it’s probably not iTween causing your slow down. I’m pretty sure it’s how much you are trying to move.

Is a game object with 30 sub objects too much?

My advice would be to try it with 5 or even 1 sub object and see if it is the quantity that is causing your slow down then go from there.
