[1.15.2] How do i make an entity change it´s collision-box-size

[Drachenbauer]

Hello

 

I have an entity, that changes it´s model to an inflated variant, if i collide with it in the game.

 

How do i make ir change it´s collision-box- / boundingbox-size, too?

Override Entity#getSize

[Drachenbauer]

In this method now i have an if else, that uses my already existing boolean to provide two size values.

But it doesn´t change the size of the box, that i can see, if i press F3 and B.

 

I have the structure, that changes the model:

    @Override
    public void livingTick()
    {
        if (timeUntilDeflating > 0)
        {
            timeUntilDeflating--;
            
            if (timeUntilDeflating == 0)
            {
                isInflated = false;
                
            }
        }
        else
        {
            super.livingTick();
        }
    }
    
    @Override
    public void onCollideWithPlayer(PlayerEntity entityIn)
    {
        if (timeUntilDeflating == 0)
        {
            timeUntilDeflating = 80;
            isInflated = true;
            
        }
    }

How do i now call it in there?

Bump:

 

Now i found out, that i have to use

recalculateSize();

there.

 

But the bigger box doesn´t fit to his position...

And if he is in water, he disappears after inflating (i was glitched into him, maybe that´s a reason, too)

 

how do i fix this?

 

Edit:

now i use this to change his boundingbox:

                AxisAlignedBB aabb = this.getBoundingBox();
                this.setBoundingBox(new AxisAlignedBB(aabb.minX + 0.5d, aabb.minY, aabb.minZ + 0.5d, aabb.maxX - 0.5d, aabb.maxY - 1.0d, aabb.maxZ - 0.5d));

I use it in "livengTick" and "onCollidewithPlayer"

Now the key F3 + B shows his boundingbox matching his bodysize, but i can run through him...

How do i make this boundingbox act as collisionbox and hitbox, too?
