Mob or Entity that Explodes on Collide with other entity and blocks?

Start new topic

Posted August 5, 20178 yr

Hello Forge community, I'm new here, I have an issue about a mob I'm creating, I want it to explode whenever it collides with a player, another entity or a block (it's a flying mob) I tried to take some codes from the enderdragon , the one that push away other mobs on collide and the one that destroy blocks on collides, here is the deal, it doesn't work here is a part of my code used for colliding with entities:

private void collideWithEntities(List<Entity> p_70970_1_)
{
for (Entity entity : p_70970_1_)
{
if (entity instanceof EntityLivingBase)
{
int i = (int) this.posX;
int j = (int) this.posY;
int k = (int) this.posZ;
world.createExplosion((Entity) null, i, j, k, 4F, true);
}
}
}

what did I get wrong?

        /**
         * This is a helper function from Tabula to set the rotation of model
         * parts
         */
        public void setRotateAngle(ModelRenderer modelRenderer, float x, float y, float z) {
            modelRenderer.rotateAngleX = x;
            modelRenderer.rotateAngleY = y;
            modelRenderer.rotateAngleZ = z;
        }
    }
}

I used the method onCollideWithPlayer like that :

public void onCollideWithPlayer(EntityPlayer entityplayer)
    {
               int i = (int) this.posX;
               int j = (int) this.posY;
               int k = (int) this.posZ;
               world.createExplosion((Entity) null, i, j, k, 4F, true);
    }

and it worked perfectly fine so no need to call the method collideWithEntities right? and by the way thanks for replying

please use spoilers (that eye on the tool bar of the editor) for logs and code tags (that <> mark on the toolbar) for code also while mcreator is not the best solution good thing that you are writing some of the code manually

sorry about that Lukas and diesieben07 that's a methode I took from EntityDragon.java so I assume this method is also called by Minecraft itself

Is there a way to modify the method onCollideWithPlayer to allow this method to work for every LivingBase Entity?

And if you checked out the original code you would see that the method is private in EntityDragon and called from the EntityDragon code.

Please learn basic programming before making a Minecraft mod.

In fact I changed the private method into a public one to see if it could work and no need to be salty. I'll do my best to find a solution and I'll post it here anyway thanks I guess

the method is called in livingTick.

I try something similar with an inflatable character, that should pusch other entitys away by colliding.

So i use the call in livingTick, too, but it still not works...

Yea i was actually coming back to mention that. I thought it was with tnt minecarts and I did use the OSC mk4. Although the OSC mk6 spreadsheet is different and keeps glitching. Also you don't have to get mad I simply thought you gave up on it.

I don't have access to JVM arguments on my dedicated server on OMGserv, what should I do? My server is actually at 11180 Mo in RAM and 59% CPU

Bro are we serious IM WORKING ON MAKING IT AS ACCURATE AS POSSIBLE

If you want it on a free server us FALIXNODES instead of aternos because aternos requires like 10k downloads before they think of adding it falix lets you add whatever

Also if you ever used the REAL ORBITAL CANNON stab shots are made of tnt not carts dummy
