How do i make an entity changing it´s model and scale if it gets damage?

[Drachenbauer]

Hello

 

I´m working on an Angry Birds-mod.

 

One of the birds (the orange one) is very small, but has the ability to inflate him self like a balloon.

 

For this one, i have 2 model-files.

 

Is there any way, how i can script, that he inflates him self for a few secconds by getting damage (by changing his model and scale from 0,5 to 1 and back to 0,5)?

 

I already managet to scale the very small birds down to 0.5 while spawning them

... Like you've said, you can change the scale from 0.5 to 1 to simulate inflating.

 

Override

Entity#attackEntityFrom

.

[Drachenbauer]

but i´l change the model too.

[DavidM]

Entity#setSize

 

[Drachenbauer]

and how to change the model, too?

 

and why you place a # in your code-pieces?

i´ve never seen that in my java-files...

1. If you just want to resize the rendered model, add an EventSubscriber for RenderLivingEvent.Pre and use GlStateManager#scale to resize the rendered model.

I want to change not only the size, i want to change the model-file too.

[DavidM]

Why do you want to change the model?

To simulate the inflating you just need to change the size of your entity.

The 2 models are not necessary.

[Drachenbauer]

If this bird is inflated in the Angry Birds games, his face and feathers look mouch smaller relative to his swollen body.

So i made a seccond model file with this look.

And i want to combine it with resizing too

How do you plan on going between the models?

[Drachenbauer]

i openet this thread, because this is my question.

[Cadiboo]

Ok, but how do you plan to smoothly transfer between two static models? Or do you not care about transferring smoothly?

[Drachenbauer]

not care, if there is no way to.

[Cadiboo]

You can load the models a couple ways. By assigning the model to a random item (may not work in 1.13) or loading the model yourself with a custom model cache.

 

You can see my code for the second method at https://github.com/Cadiboo/WIPTech/blob/fb5883e9d76ef0361ec1ebbcb9c508611dd2ef6b/src/main/java/cadiboo/wiptech/client/ClientEventSubscriber.java#L97, https://github.com/Cadiboo/WIPTech/blob/WIPTechAlpha/src/main/java/cadiboo/wiptech/client/render/entity/EntityRailgunRenderer.java, https://github.com/Cadiboo/WIPTech/blob/fb5883e9d76ef0361ec1ebbcb9c508611dd2ef6b/src/main/java/cadiboo/wiptech/client/ClientEventSubscriber.java#L180-L214 and https://github.com/Cadiboo/WIPTech/blob/WIPTechAlpha/src/main/java/cadiboo/wiptech/client/model/ModelsCache.java. With this approach, any non-vanilla textures you need must be loaded in the texture stitch event

[Drachenbauer]

Now i have both model-classes with their renderer-classes.

 

How can i switch bitween the renderers, if the entity collides with the player (i think, that´s better than damage, so i can cause him to inflate, withouf damage him)?

I found this mothod for the collision.

    @Override
    public void onCollideWithPlayer(PlayerEntity entityIn)
    {
        super.onCollideWithPlayer(entityIn);
    }

What must i put in there to cause a change to the other renderer?

 

During another project, i found a way to make it first do stuff, than wait a time, than do other stuff:

With this i will make him inflate in the moment of the collision and deflate 4 seconds later:

    @Override
    public void onCollideWithPlayer(PlayerEntity entityIn)
    {
        //command for inflate
        timer.schedule(new TimerTask()
        {
            @Override
            public void run()
            {
                //command for deflate after 4 seconds
            }
        }
        , 4000);
        
        super.onCollideWithPlayer(entityIn);
    }

But what must i put above and inside the timer to change the renderer for this instance of the entity?

I would have a field on my entity that would store the time since it was last hit, set it to 0 in that method and increment it each tick.

do NOT do this.

Why i should not do this timer thing?

In my other project (a simple sokoban-game, nothing about minecraft) it works fine.

 

And how do i increase a time-field by tick?

Is this better:

    @Override
    public void livingTick()
    {
        timeUntilDeflating++;
        
        if (timeUntilDeflating >= 80)
        {
            //command or deflating here
        }
        
        super.livingTick();
    }
    
    @Override
    public void onCollideWithPlayer(PlayerEntity entityIn)
    {
        timeUntilDeflating = 0;
        //command for inflating here
    }

what i need is, how to change the renderer for this instance, because the proportions of this bird change, if he inflates himself.

His body expands, but his face and feathers stax the same size.

So i have two renderers, wich use different models.

If i register both in my render-handler, the seccond one is used for the entity.

At first i thaught, maybe it will render both at the same place, doing the same stuff in the same moment.

But that isn´t the case.

 

so what must i put in the command-spots of the piece of code in my last post to change the renderer for this instance?

[Drachenbauer]

I have got an idea:

I can create the inflated version as an own entity without living animations.

And in the original entity of the bird, it should spawn the inflated version at it´s position, if i collide with him and despawn it after the four secconds, i declared in the living-tick.

And while theese four secconds, the normal one should do no living animations to stay hidden inside the inflated model.

 

My code in the entity-class for this so far:

    @Override
    public void livingTick()
    {
        if (timeUntilDeflating > 0)
        {
            timeUntilDeflating--;
            
            if (timeUntilDeflating == 0)
            {
                //command for deflating here
            }
        }
        else
        {
            super.livingTick();
        }
    }
    
    @Override
    public void onCollideWithPlayer(PlayerEntity entityIn)
    {
        if (timeUntilDeflating == 0)
        {
            timeUntilDeflating = 80;
            //command for inflating here
        }
    }

It actually makes the entity stop it´s whoole movement and animations for four secconds after a collision with the player.

I´ll use this effect to keep the normal model hidden inside the inflated one.

 

I´m still working on an abstract renderer, that uses a model-class and scalefactor, but no living-animations (for the inflated variant).

 

How do i write a command, that spawns the inflated entity and fits in here?

And one that despawns it?

It should be spawned in the actual position of the normal one (to encase it) and with it´s rotation-angle around the vertical axis.

Now i use two models ant e texture, thad holds stuff for both models to simulate his inflating skill.

This worked well.

Then i thaught about resizing his boundingbox to fit the two different sizes.

Now he disappears, if i run into him to make him inflate.

I created theese boundingboxes:

    protected static final AxisAlignedBB BBUBBLES_AABB = new AxisAlignedBB(6.0D, 0.0D, 6.0D, 12.0D, 4.0D, 12.0D);
    protected static final AxisAlignedBB BBUBBLES_INFLATED_AABB = new AxisAlignedBB(-2.0D, 0.0D, -2.0D, 18.0D, 20.0D, 18.0D);

 

and use them in theese methods:

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

in ormal state he is a 4x4x4 pixels (1/4 block-edgelength) cube and inflated 20.2.x2.pixels (a bit bigger than a block)

Is something wrong with my boundingboxes?
