[SOLVED] How to add healthbar that is affected by raycasts

Help & Support

This is the relevant code

Gun.prototype.Shootytwo = function() {
    for(i=0;i<this.pellets;i++)
    {
        if (this.app.mouse.isPressed(pc.MOUSEBUTTON_RIGHT))
        {
            this.bulletentitytwo.setLocalEulerAngles((Math.random() * this.accuracy) - (this.accuracy / 2), (Math.random() * this.accuracy) - (this.accuracy / 2), (Math.random() * this.accuracy) - (this.accuracy / 2));
        }
        else
        {
            this.bulletentitytwo.setLocalEulerAngles((Math.random() * this.inaccuracy) - (this.inaccuracy / 2), (Math.random() * this.inaccuracy) - (this.inaccuracy / 2), (Math.random() * this.inaccuracy) - (this.inaccuracy / 2));
        }
        this.bulletentitytwo.children.forEach((enabloid) => {
            enabloid.enabled = true;
            enabloid.setLocalEulerAngles(0, 0, Math.random()*360)
        });
        anglePos = this.bulletentitytwo.forward.clone();
        anglePos.scale(this.range);
        from = this.bulletentitytwo.getPosition();
		result = this.app.systems.rigidbody.raycastFirst(from,anglePos.add(from));
		if(result)
        {
		    if(result.entity.tags.has(this.enemytag))
            {
		            result.entity.translateLocal(0,-50000,0);
			        result.entity.sound.play("sound");
                    Grams += this.damage;
                    //Grams += ((Math.floor(Math.random() * 6)) + 1);
		    };
        };
    }
};

Currently it just translates the entity as a placeholder. Can anyone tell me how to have individual entity specific health and to lower it by a given amount?

Hi @ALUCARD!

I decided to update my basic shooting example with an enemy that has a health bar.

With the collision of the bullet I execute the function on the enemy to update the health bar. You can basically do the same with your raycast hit.

Using the physical size of an entity as the health? That seems very floating point errory. Actually it might be better if the code changed a hidden text entity so precise health could be achieved, either that or parsefloat the name.

This is an example I made. You can change it anywhere you want to make it more stable or whatever.

I already made a far superior version. I believe the entire example will be finished within a few days. Also mark this as solved.
