Increase player speed

Recommended Posts

Replace

player.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setAttribute(0.5d);

with

player.moveEntityWithHeading(player.moveStrafing, player.moveForward * timesFaster);

where "timesFaster" is how many times faster you want the player to be. For example, 1.5 for the player to be 50% faster, or 2 for the player to be 100% faster.

@MikaXD - this method does work but the problem with it is that even after I take the armor off the player still walks at the faster speed, I'm not sure how to fix that.

 

@MrIbby - your method works pretty well, and the effect stops after you take the boots off, but the problem with it is that it affects jumping and makes it that you land very fast after jumping, is there a way to address that?

 

Thanks to both of you!

For MikaXD's -

 

You could set the Player speed back to default using an event of some sort, when the Player removes the boots. It's simple and I haven't tried it myself so I couldn't tell you how efficient or nonefficient it might be.

 

For MrIbby's -

 

I could be wrong, but I think there's a jump...thing in attributes too, or maybe in the 'capabilities' constructor. As I said, I'm about 95% sure I'm wrong, but I suppose it can't hurt to look, you never know. Also it helps to open the packages up in Minecraft and look directly for the type of file you want. It's helped me out dozens of times.

@Alpha wolf, What you're saying makes sense but the problem is I dont know where I should reset the speed, does anyone know what method I can put it in?

You could use player.capabilities.setPlayerWalkSpeed(1), which sets it back to its original speed. :) It's simple, but should, should work.

I know, but WHERE do I put that is the question. I currently have things in the onArmorTickUpdate, but when the armor is off that method doesn't get called anymore and it never gets set back. I need a method that runs everytime armor is taken of, does anyone know of a method like that?

Thanks to all your help I was able to get everything working fine, with the speed going back to normal after armor is off. However, when I ran the mod on a server, It kicked me out immediately after putting on the armor, here is the log

By SERVER side, you mean when !world.isRemote and not @SideOnly(Side.SERVER), right? The first would be the correct syntax.

 

If that's not your problem, then is it possible the server is running an older version of Forge than your mod requires? What I mean is, perhaps the setWalkingSpeed method is still obfuscated on the server's version. Just a thought.

 

An alternate solution, one that I use, is to apply a speed modifier based on SharedMonsterAttributes. You can do this either as a value you add directly to your armor in getItemAttributeModifiers, which would be applied even while holding the armor in hand, not just when worn, or by applying (and removing) the same attribute modifier via your tick handler to get the 'only when equipped' effect.

Both world.isRemote and SIDE yield the same results. When its client side only, the custom effects aren't implemented, when its server side, I get kicked out as soon as armor is on.

 

Here is the code If its of any help

 

 
public void onArmorTick(World world, EntityPlayer player, ItemStack itemStack)
    {
	      
    	        float bootsOn = 0;
		float legsOn = 0;
		float chestOn = 0;
		float helmOn = 0;

		if(player.getCurrentArmor(0) != null ){

			ItemStack boots = player.getCurrentArmor(0);
			if(boots.getItem() == SoulCraft.soulBoots2)  bootsOn = 0.1f;


                         }

		player.stepHeight = 1;

		if(player.getCurrentArmor(1) != null ){ 

			ItemStack legs = player.getCurrentArmor(1);
			if(legs.getItem() == SoulCraft.soulLeggings2) legsOn = 0.05f;

		}

		if(player.getCurrentArmor(2) != null ){

			ItemStack chest = player.getCurrentArmor(2);
			if(chest.getItem() == SoulCraft.soulChest2) chestOn = 0.05f;

		}

		if(player.getCurrentArmor(3) != null ){

			ItemStack helm = player.getCurrentArmor(3);
			if(helm.getItem() == SoulCraft.soulHelmet2) helmOn = 0.05f;

		}


		if (player.isSprinting()) player.capabilities.setPlayerWalkSpeed(0.1f + bootsOn + legsOn + chestOn + helmOn);

		else player.capabilities.setPlayerWalkSpeed(0.1f);


    }

Does anyone know of a way I can fix this, or another approach that wont give me troubles? Thanks

I mentioned earlier about SharedMonsterAttributes and AttributeModifiers, try using those instead of setPlayerWalkSpeed. Take a look at the sprinting mechanic as an example (specifically, see EntityLivingBase#setSprinting method and the related fields).

FOV is affected (slightly) by the player's current speed - if your screen was going crazy, then perhaps consider toning down your speed boost? I haven't looked at the setPlayerWalkingSpeed method, so I'm not sure how much that affects the player speed relative to something like sprinting, but in my own mod, I've created various items that in combination can will boost the player's speed by about as much as though they were sprinting x 3 or 4, and the player can sprint on top of that, which brings the player up to a pretty ridiculous speed yet without any extremely jarring zoom effect. If you go much faster than that, new chunks will have a very difficult time loading quickly enough and you will probably encounter other errors.

Sure. You can view my entire source on Github (sorry, it's the 1.6.4 version of my mod on there still!), and here is a relevant snippet from the 1.7.x version (which is pretty much unchanged from 1.6):

 

 

/** Movement bonus for wearing Pegasus Boots */
private static final UUID pegasusBootsMoveBonusUUID = UUID.fromString("36A0FC05-50EB-460B-8961-615633A6D813");

private static final AttributeModifier pegasusBootsMoveBonus = (new AttributeModifier(pegasusBootsMoveBonusUUID, "Pegasus Boots Speed Bonus", 0.3D, 2)).setSaved(false);

// whenever the player changes footwear, a method is called with this code:
IAttributeInstance movement = player.getEntityAttribute(SharedMonsterAttributes.movementSpeed);

if (movement.getModifier(pegasusBootsMoveBonusUUID) != null) {
movement.removeModifier(pegasusBootsMoveBonus);
}
// remove other possible modifiers

ItemStack boots = player.getCurrentArmor(0);
if (stack != null) {
if (stack.getItem() == ZSSItems.bootsPegasus) {
movement.applyModifier(pegasusBootsMoveBonus);
}
// other boots 
}

 

 

That's pretty much all you need. I use the exact same modifier value of 0.3D and operator '2' (which adds 30% of the current speed value, see the wiki) for almost all of my speed enhancing items and effects; using multiple of these at the same time, sprinting or running, has not yet caused any problems for me.
