Testing Held Item

[J-Nutz]

I currently have an item that on right click grants the player creative flight. When either right clicked again, or the player selects another item/empty hand the flight gets taken away. How would I do that? My current code doesn't do so.

 

ItemStack heldItem = player.getCurrentEquippedItem();

if(heldItem.getItem() != ToolInits.flightWand)
{

	allowFlight = false;

}

Could you show me an example? Everything I try seems to crash my game. I tried it with out the statement and it doesn't crash so It's not something else.

ItemStack heldItem = player.getCurrentEquippedItem();
if (heldItem != null)
{
if (heldItem.getItem() != ToolInits.flightWand)
{
	allowFlight = false;
}
}

 

Those are literally basics. If that is not the case, please post full code and/or what you are trying to do.

That works, but how would I get it to set allowFlying to false if your hand is empty? That's what crashes

[shadowfacts]

Hold on, while there is no item in the player's hand you want them to be able to fly? And when they are holding your item they can't fly? That makes no sense whatsoever.

Umm, No... I just said "how would I get it to set allowFlying to false if your hand is empty?"

 

On right click it allows the user to fly, if you right click or choose another item, the flight is taken off.

Where's the confusion?

Some time ago there was similar problem posted. Someone wanted to execute some code (turn off buff) JUST AFTER you swapped item in hand (stopped holding it).

 

Problem here is that there is NO method called there.

BUT, there is a way of doing it.

 

This might be outdated, but I doubt there is other way for now:

1. Add IExtendedEntityProperties to EntityPlayer (may be even server-side only since Inventory is there)

2. Add a boolean flightItemBeingUsed = false;

3. Since you are activating flight by right-clicking (item use) you will use this:

ExtendedPlayer.get(player).flightItemBeingUsed = true;

4. Now: Subscribe to PlayerTickEvent and write:

if (ExtendedPlayer.get(player).flightItemBeingUsed)
{
ItemStack heldItem = player.getCurrentEquippedItem();
if (heldItem != null && heldItem.getItem() == ToolInits.flightWand)
	allowFlight = true;
else
{
	allowFlight = false;
	ExtendedPlayer.get(player).flightItemBeingUsed = false;
}
}

 

I belive this should work. Also - you could obviously do it MUCH simplier without using IEEP, BUT then your mod will be incomatybile with other fight-allowing commands/mods/items.

 

Edit: made simple change in code. Also - this is almost pseudo-code (written it without IDE), you SHOULD be able to optimize it a bit. (I think)

[J-Nutz]

Hmm, The .get() Method seems to not work

[Ernio]

You have no idea how to use IEEP, do you?

Anyway - this is the moment that you decide to either spend week learning new (very useful) feature that will come in handy later, or you say "nope" and start coding incompatybile stuff or simply not coding what you want.

Funny how i link this tutorial this many times

 

You should make new class for IEEP interface,  .get(EntityPlayer) is my wrapper for getting IEEP of given PlayerEntity (see tutorial).

Sorry, Was up too late to be attempting to code. I understand now. Thank you for your time and help! Much appreciated.
