Hello everyone,

I've made a "onPlayerTick" function which is working great but i've got a little problem.

private void onPlayerTick(EntityPlayer player) {
	ItemStack plate = player.getCurrentItemOrArmor(3);

	if (plate != null) {
		if (plate.getItem() == Items.jetpack) {
			if(player.isJumping){
				player.worldObj.spawnParticle("heart", player.posX, player.posY - 1, player.posZ, 0.0D, 0.0D, 0.0D);
				player.motionY += .15F;
			}
		}
	}
}

On singleplayer the particle work correctly but on multiplayer, the other players cant see it. Any solutions?

Bump plz

can you check that other players see "isJumping" as a good value, this might not be updated through all the clients :\

So in the "onWorldTick" i do something like that ?

for (Entity e : world.getEntities()){
    if (e instanceof EntityPlayer) {
        if (e.getArmor(3) != null & e.getArmor(3).getID() == Items.plate & e.isJumping)[
             //Show particle
        }
    }
}

no, you use System.out.println() to check wether or not the variable "isJumping" is true for other players when a player is jumping, like i said this variable might not necessarelly be synchronized with all the clients

Where am I supposed to write this? Because onPlayerTick seems only tick the client player (But its in the ServerTickHandler)

 

I've got another problem. I rewrited the mod because I changed computer and forget to save it

But the coremod doesnt work. Its written this in the log:

2013-08-17 19:59:21 [iNFO] [ForgeModLoader] FML has found a non-mod file KnuxCore.jar in your mods directory. It will now be injected into your classpath. This could severe stability issues, it should be removed if possible.

And the variable isJumping now return ALWAYS false.

Thats what currently has the tick

public void playerTick(EntityPlayer player) {
		ItemStack is = player.getCurrentArmor(2);
		if(is != null){
			if (is.getItem() == Items.jetpack){
				System.out.println("isJumping: " + player.isJumping);
			}
		}
}

And my console is spammed with "isJumping: false" when i am ingame, both if i jump or not

When do you call this method ?

onPlayerTick is in the tick handler which is registred with

TickRegistry.registerTick(new TickHandlerServer(), Side.SERVER);

You know you can register ticks on client side too, don't you ?

Yes I know, but if i do this, the client will be kicked because "Flight is not enabled", doesnt it ?

And for the particle I probably should do that. Let me try

All you need is isJumping set to true at some point.

The rest you can handle with packets if needed.

 

Edit: You can use LivingJumpEvent instead of a TickHandler, too.

This event seems not to work. It happens when player is on ground then jump, but when its in the air, the event is no longer called, even if the keyboard stay pressed
