Problem with player.setGameType(EnumGameType.CREATIVE);

Hi there!

I try to explain my Problem in short words:

I'm playing around with KeyBindings. I took an old Item an added an "onUpdate(bla bla)". I also created the KeyHandler to get the Information if the specific Key is pressed. While playing around, I made the Key working as an toggle. This toggle should switch between Survival and Creative. Long story short: If I press the key with the item in my hand, the toggle works  as it should. I can see this, cause I have a player.addChatMessage() in the onUpdate, too. The problem now is, that the gamemode doesn't change everytime I press the key (the ChatMessage appears!). I think it changes every 5 to 100 time I press the key.

If someone please could watch the code and tell me what the fault is

Thanks alot!

The part in the IconFile:

boolean gameTypeCreative = false;
boolean gameTypeSurvival = true;
public void onUpdate(ItemStack par1ItemStack, World par2World, Entity par3Entity, int par4, boolean par5)
{
	EntityPlayer player = (EntityPlayer)par3Entity;

	if(KeyBindingHandler.keyPressed & par1ItemStack==player.getHeldItem())  
	{
		if(gameTypeSurvival==true) {
			player.setGameType(EnumGameType.CREATIVE);
			player.addChatMessage("Creative an! gTC=" + gameTypeCreative + " / gTS=" + gameTypeSurvival);
			gameTypeSurvival = false;
			gameTypeCreative = true;
		} else  {
			player.setGameType(EnumGameType.SURVIVAL);
			player.addChatMessage("Survival an! gTC=" + gameTypeCreative + " / gTS=" + gameTypeSurvival);
			gameTypeSurvival = true;
			gameTypeCreative = false;
		}

	}
}

And the KeyBindingHandler:

package ...

public class KeyBindingHandler extends KeyHandler // implements ITickHandler
{
         private EnumSet tickTypes = EnumSet.of(TickType.CLIENT); // With PLAYER it's the same issue.
         public static boolean keyPressed = false;
         public static boolean keyReleased = true;
        
         public KeyBindingHandler(KeyBinding[] keyBindings, boolean[] repeatings)
         {
                 super(keyBindings, repeatings);
         }
         @Override
         public String getLabel()
         {
                 return "CustomKey";
         }
         @Override
         public void keyDown(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd, boolean isRepeat)
         {
        	 
        	 if (keyReleased==true) {
        		 keyPressed = true;
        		 //System.out.println("pressed");
        	 }
        	 else {
        		 keyPressed=false;
        	 }
        	 keyReleased = false;
         }
         @Override
         public void keyUp(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd)
         {
        	 
        	 if (keyReleased==false){
        		 keyPressed = false;
        	 keyReleased = true;
        	 //System.out.println("released");
        	 }
         }
         @Override
         public EnumSet<TickType> ticks()
         {
                 return tickTypes;
         }
}
