How to make entity not move?

[Warix]

Hello i need to make vanilla entities not move when they have specific extended property on them. I tried with removing AI (cleared tasks and targetTasks lists) but that doesn't work for all ( e.g. bats have their own code for moving around). I was thinking of setting entity's position to fixed location from update entity event but that isn't good solution and its also acting weird.

Thanks that worked . Only that method was protected so i had to use this code directly.

event.target.getDataWatcher().updateObject(15, Byte.valueOf((byte)(1)));

Ok, but i wasn't , i'm doing this from event and for all entities(including vanilla).

 

	@SubscribeEvent
public void EntityInteractEvent(EntityInteractEvent event) {

	//Demons extract wand
	if (event.entityPlayer.getHeldItem() != null && event.entityPlayer.getHeldItem().getItem() == AkameItems.demons_extract_wand) {
		if (event.target instanceof EntityLivingBase) {
			EntityExtendedProperties.get((EntityLivingBase) event.target).setFrozen(true);
			if(event.target instanceof EntityLiving)
			{
				event.target.getDataWatcher().updateObject(15, Byte.valueOf((byte)(1)));
			}
		}
	}

Also how can I make my custom AI work if I disable all other this way. Because i will need it for another item , I will need it to  disable all current entities AI and add my own.
