[1.6.4]Making a player move

[starwarsmace]

Hello. I'm making a mod and want move over two blocks on item right click. Is there a way to do that?

[starwarsmace]

Please help!! I really need this for my mod.

And by "move" you mean teleport entity (player) 2 blocks in some direction (probably front), or actually just a normal movement like on "FORWARD" key that will end after 2 blocks? If the second one, well, are you also considering player walking speed (potions/soulstone) or just want player to walk 2 blocks with "normal" speed? Also: you do understand that if you are alredy walking e.g. forward, and make player walk "again" forward (by rightclicking) this will not stack - I mean, it depends if you will launch single movement or movement over tick.

I meant teleport and no I didn't realize it won't stack but thats fine.

Well, there are many ways to do the teleportation thing (because "normal" walking process would be harder - that's why I asked).

You could make setPositionAndUpdate() and call it inside your onItemRightClick() method.

Rest of the code (x,y,z) coords are just math thing, so I am guessing you know how to get entity position, don't you?

I am not sure about rotation after teleportation, so if it wont be same as beforte event, you could save players rotation yaw, and then set it after the teleportation event.

Edit:

Well, just read:

/**
     * Move the entity to the coordinates informed, but keep yaw/pitch values.
     */
    public void setPositionAndUpdate(double par1, double par3, double par5)
    {
        this.setLocationAndAngles(par1, par3, par5, this.rotationYaw, this.rotationPitch);
    }

So, no, Yaw stays the same.

Also: If you want to make sure that player wont be travelling inside of blocks, you can get world max y for (x/z).

Ok will try this.

[starwarsmace]

I tried what you said but for some reason it teleported me far up.

 

Heres my code.

 

player.setPositionAndUpdate(player.posX+2, player.posZ, player.posZ);

[Ernio]

Really?

You set posZ twice.

Fixed:

player.setPositionAndUpdate(player.posX+2, player.posY, player.posZ);

Also:

(x,y,z) are coordinates of entity in the WORLD, not in entity coord plane. That means that adding +2 will move your entity in world's grid.

You need to either use Math() to get direction that will be added to (x,z) or... Well, this is pretty much only option

 

Edit: And yeah - diesieben07 alredy answered, sry.

 

Edit: For getting player's rottationYaw check out debug in GuiIngame (search for this.mc.mcProfiler.startSection("debug").

Or maybe they added some function that returns rotation automatically? (well, i am using my own Util from 1.1 or earlier so, I don't know)

Just realized I did it twice. Silly mistake.

 

 

Also I've ,never really used the Math(). So could you give me some code to work with? Thanks.

Dude... Saying "never really used the Math()" is like saying you are a 12 year old and suck in school.

Java Math() is just a math. Can't help here if you don't understand what a f(x)=sin(x) is.

I can only tell you how to "kinda" make it.

1. float yaw = mc.thePlayer.rotationYaw; //returns total spin yaw of player during Entity existance (read: moment you join the world)

2. Wrap your yaw into smaller values (http://en.wikipedia.org/wiki/List_of_trigonometric_identities)

3. MathHelper.wrapAngleTo180_float(yaw);

4. Do the math for x and z coordinate - well, you can make it even using Pythagoras and sin(x) - I prefere better ways.

5. You got your x and z, now launch:

player.setPositionAndUpdate(player.posX + x, player.posY, player.posZ + z);
