I am adding enchants to my mod and one of them is to increase the speed when wearing enchanted leggings. I made a tick handler to check every tick whether the player is wearing enchanted leggings and then increase the motionX and motionZ of the player. Here is what I have so far.

@Override
public void tickStart(EnumSet<TickType> type, Object... tickData)
{
	EntityPlayer player = (EntityPlayer) tickData[0];

	int speedLvl = EnchantmentHelper.getEnchantmentLevel(
	        TuxWeaponsCore.enchSpeed.effectId,
	        player.getCurrentArmor(1));

	if(speedLvl > 0)
	{

		player.motionX *= 2D;
		player.motionZ *= 2D;
	}
}

It knows when the leggings are being worn it just won't give the necessary speed boost. I'm not sure what is wrong, I have tried putting the code in both tick start and tick end.

Could you have used code for the haste enchant for this?

try making your tickHandler look like this:

package yourMod;


public class TickHandlerYourMod implements ITickHandler {

private void onPlayerTick(EntityPlayer player) {


	if(player.getCurrentItemOrArmor(2) != null){
		ItemStack leggings = player.getCurrentItemOrArmor(1);
		if(leggings.getItem() == yourMod.yourLeggings){
			player.addPotionEffect((new PotionEffect(Potion.moveSpeed.getId(), 60, 0)));
		}
	}

}

@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.SERVER);
}

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

}

 

and then tweak it for the enchantment part

 

hope this helped!

the source of the player movement speed seems to originate from EntityLiving.getSpeedModifier() and there doesnt seem to be any way to change this without vanilla change. This would make a good PR.
