Hello

I have created a projectile that that needs to obey gravity.  I have made sure that i call this.setNoGravity(false); in the constructor.   How ever it doesnt obey gravity.  Here is my current code:

 

package com.drok.progressiveg.entity.projectile;

import com.drok.progressiveg.GunMod;

import net.minecraft.entity.Entity;
import net.minecraft.entity.IProjectile;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.util.math.RayTraceResult;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.registry.IThrowableEntity;

public class EntityLeadBullet extends Entity implements IThrowableEntity {

	
	public EntityLeadBullet(World worldIn) {
		super(worldIn);
		this.setSize(0.5F, 0.5F);
		this.setNoGravity(false);
	}

	@Override
	protected void entityInit() {
		// TODO Auto-generated method stub
		
	}

	@Override
	protected void readEntityFromNBT(NBTTagCompound compound) {
		// TODO Auto-generated method stub
		
	}

	@Override
	protected void writeEntityToNBT(NBTTagCompound compound) {
		// TODO Auto-generated method stub
		
	}
	
	protected void onHit(RayTraceResult raytraceResultIn)
    {
    }
	
	@Override
	public void onUpdate()
    {
		super.onUpdate();
		GunMod.log("onUpdate");
		
    }

	@Override
	public Entity getThrower() {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public void setThrower(Entity entity) {
	
	}

}

 

I don't know much about Minecraft programming but I am a reasonably good programmer (smiple, high-level multiclass game from relative scratch).

Therefore, my humble suggestion: You did not put obeysgravity as a parameter anywhere in the consructor. So perhaps it's just that it doesn't personally have any gravity settings, only the class itself (this) does. It would also be helpful if you included the Entity class (we know virtually nothing about the setNoGravity variable otherwise.

Thanks!

I have set it to obey gravity by calling

this.setNoGravity(false);

And i have provided my Entity class

Yeah no I meant the Entity class that EntityLeadBullet was extended from, not EntityLeadBullet itself.

If you are making a mod then you should have access to the Entity class.  If your not making a mod then i do not believe this is a section for you although i do appreciate you trying to help.

No one has any idea why this is happening?

i solved my own problem.  It turns out i had to manually set the motion and position of my entity.

You can make the entity extend net.minecraft.entity.projectile.EntityThrowable.

You're right, and thanks for the politeness. I'm super interested in modding tho. Congrats on the fix!
