Launching Rail Momentum Problem

Recommended Posts

Hello!

 

I have been having a problem with my custom Launching Rail where the minecart is launched into the air however it has too much vertical speed and needs more horizontal speed. I have been looking around in the EntityMinecart class however I have not found anything that can help me doing this.

 

Rail Code:


package thedecopack.medieval.blocks;

import net.minecraft.src.*;

import java.util.List;
import java.util.Random;

import thedecopack.medieval.DecoMedieval;

public class BlockMedievalJumpRail extends BlockRail
{

public BlockMedievalJumpRail(int par1, int par2)
{
	super(par1, par2, true);
	setCreativeTab(DecoMedieval.medievalTab);
}

/**
 * Triggered whenever an entity collides with this block (enters into the block). Args: world, x, y, z, entity
 */
public void onEntityCollidedWithBlock(World par1World, int par2, int par3, int par4, Entity par5Entity)
{
	if (!par1World.isRemote && par5Entity instanceof EntityMinecart)
	{
		EntityMinecart mineCart = (EntityMinecart)par5Entity;
		mineCart.motionY += 0.4F;
	}
}

public float getRailMaxSpeed(World world, EntityMinecart cart, int y, int x, int z)
{
	return 0.4F;
}

public String getTextureFile()
{
	return DecoMedieval.instance.blockTextureFile();
}
}

Put minecart.motionX * 3

minecart.motionZ * 3

 

What this does is it takes your x and z moumentum and times it by 3 the key here is that it times it because if it is not going along the  x then adding moumentum to the x will be z will be 3 times the speed

Syntax error on token "*", invalid AssignmentOperator

		mineCart.motionY += 0.4F;
		mineCart.motionX * 3;
		mineCart.motionZ * 3;
