Player motionY?

[SeKtOR]

I solved my issue with "CommonTickHandler" big thanks to guy, who help me... Current issue with thePlayer.motionY(it's not working or i do something wrong)

My code

//thePlayer - instance of EntityPlayerMP
thePlayer.capabilities.allowFlying = true;
thePlayer.motionY *= 3.0; // Only for test
thePlayer.capabilities.isFlying = true;
thePlayer.fallDistance = 0;  

Player motionY doent's changed, but fallDistance work...

P.S. Sorry for bad english...

[SeKtOR]

I tried "System.out.println(thePlayer.motionY)" it's print "-0.078.....". Also if i run across world nothing changed motionY ignored...

P.S. Changed motionY *= 3.0 to motionY += 3.0. Nothing changed...

Current code:

        thePlayer.capabilities.allowFlying = true;
thePlayer.capabilities.isFlying = true;
thePlayer.motionY += 3.0; // Only for test
thePlayer.fallDistance = 0;

I want make something like "Hugh Jump Boots". After some studying i can really understand java code and want code

[SeKtOR]

TickHandler(server)

package (mod package);

import java.util.EnumSet;
import java.util.ArrayList;
import java.util.Iterator;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.server.MinecraftServer;
import net.minecraft.network.packet.Packet3Chat; // Will removed
import net.minecraft.item.ItemStack;
import cpw.mods.fml.common.ITickHandler;
import cpw.mods.fml.common.TickType;
import cpw.mods.fml.server.FMLServerHandler;
import (mod package).*;

public class TickHandler implements ITickHandler 
{		
@Override
public void tickStart(EnumSet<TickType> type, Object... tickData) 
{
if(type.equals(EnumSet.of(TickType.PLAYER)))
{
ArrayList players = (ArrayList) MinecraftServer.getServer().getConfigurationManager().playerEntityList; // Wlll replace with FMLServerHandler
Iterator parray = players.iterator();
// Players armor check!
while(parray.hasNext()) {
    EntityPlayerMP thePlayer = (EntityPlayerMP) parray.next();	
ItemStack helmet = thePlayer.inventory.armorItemInSlot(3);
ItemStack body = thePlayer.inventory.armorItemInSlot(2);
ItemStack legs = thePlayer.inventory.armorItemInSlot(1);
ItemStack boots = thePlayer.inventory.armorItemInSlot(0);
if(helmet != null) {
// do something...
}

if(body != null) {
// do something...
}

if(legs != null) {
// do something...
}

if(boots != null) {
if(boots.itemID == (main mod class).bootsPremium.shiftedIndex) {
System.out.println("Player has boots");
    thePlayer.capabilities.allowFlying = true;
thePlayer.capabilities.isFlying = true;
thePlayer.motionY = 10.0; // Only for test
thePlayer.fallDistance = 0;  
//System.out.println(thePlayer.motionY);
}
}

}
}
// End Players armor check!
}

@Override
public void tickEnd(EnumSet<TickType> type, Object... tickData) 
{

}

@Override
public EnumSet<TickType> ticks() 
{
	return EnumSet.of(TickType.PLAYER);
}

@Override
public String getLabel() 
{
	return null;
}

}

Also in main mod class

TickRegistry.registerTickHandler(new TickHandler(), Side.SERVER);

I'm guessing this is in a tick handler, i'm having the same problem, it will update the velocity if the player takes damage it seems, so it could be that the velocity isn't updated through this method without something else happening to the player. Not sure how to do this

 

 

Here is the tick handler as i have it (i'm guessing his is similar)

 

import java.util.EnumSet;

import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.player.EntityPlayer;
import cpw.mods.fml.common.ITickHandler;
import cpw.mods.fml.common.TickType;

public class ServerTickHandler implements ITickHandler
{

public static EntityPlayer thePlayer;

@Override
public void tickStart(EnumSet<TickType> type, Object... tickData) 
{
	if (type.equals(EnumSet.of(TickType.PLAYER)))
	{
		onPlayerTick((EntityPlayer)tickData[0]);
	}
}

@Override
public void tickEnd(EnumSet<TickType> type, Object... tickData)
{

}

@Override
public EnumSet<TickType> ticks()
{
	return EnumSet.of(TickType.PLAYER, TickType.CLIENT);
}

@Override
public String getLabel()
{
	return "My Tick";
}

private void onPlayerTick(EntityPlayer player) 
{
	player.motionY = 1;
}
}

I think this ticker dont work on server side because:

 @Override
public EnumSet<TickType> ticks()
{
  return EnumSet.of(TickType.PLAYER, TickType.CLIENT);
}

i've tried with both, it seems to work the same both way, it's just i didn't bother changing it before posting as i was changing it to see whether it was the tick type that was the problem

[edit]

i just realised what you meant, yeah that's probably true, not got a way to try it though

[Yagoki]

just found something else that's odd.

I told it to print the motionY before and after setting it to 1. oddly the speed it was saying before was not equal to 0 whilst standing still, instead it was a bit lower than what i was setting it to. (told it to set it to 1, and it said the initial velocity was 0.907....    told it to set it to 2 and it said it started at 1.8.....) this is odd and may shine some light on our problem.

 

[EDIT]

after my player.motionY=2, it seems that it is normally at -0.0784000015258789 whilst stationary. guess this is gravity or something

[SeKtOR]

Up

[SeKtOR]

I find something strange: if enable fall damage and get it "motionY" will triggered and player make high jump...

[Yagoki]

that's what i found here too

[Yagoki]

Just had the brilliant idea of scrolling through github to see if there were any open source mods which had done this.

Looking in the source for MachineMuse modular power suits (Epic mod, try it out) In the tick data they only specified TickType.PLAYER. not player and server. not tried it yet, and it may be a while before i can, but give this a go and see what you can do (tell me what you manage so i know if it works when i get round to doing this)

 

I'll post a link to the source so you can look yourself and see what you think

https://github.com/MachineMuse/MachineMusePowersuits/blob/master/src/minecraft/net/machinemuse/powersuits/tick/PlayerTickHandler.java

I GOT IT WORKING!!!!!!!!!!

just had to register it in the client proxy aswell

 

the code is now just the same (player.motionY += number in tick handler) with it regesterd as

TickRegistry.registerTickHandler(new TickHandler(), Side.SERVER);

in common proxy and

TickRegistry.registerTickHandler(new AAPlayerTickHandler(), Side.CLIENT);

in the client proxy

YAY IT WORKS
