How to create an entity with properties and textures of a block

[alimrv]

Hello everyone!

I recently started learning Minecraft modding and I'm currently trying to figure out how to work with entities . My goal is to move the block the player is looking at three blocks up . Now I've figured how to move the block but I wanted to add some animations to it and I decided to summon an entity and move it upwards and delete it and then summon my block again. But the problem is I can't any way to summon an entity . All the videos on YT are about making custom entities or block entities . And my second question is how can I move it afterwards . Can I apply some kind of force ?

There are many ways to summon an entity.

Since you want to give it an initial velocity, have a look at GhastShootFireballGoal.

For rendering a block during entity rendering, look at the FallingBlockRenderer, used for things like falling sand or dropping anvils.

Well , how can I replace my fireball's texture with a grass block . I couldn't figure it out.

public class EntityGrass extends FallingBlockEntity {

    Vec3 vec = Vec3.ZERO;
    BlockPos pos;
    ServerLevel level;
    BlockState state;
    int i;

    public EntityGrass(EntityType<? extends FallingBlockEntity> entityType, ServerLevel level , BlockPos pos , BlockState state, int i) {
        super(entityType, level);

        this.pos = pos;
        this.level = level;
        this.state = state;
        this.i = i;
    }

    @Override
    public void tick()
    {
            setNoGravity(true);

            if(this.time >= 6)
            {
                placeBlock(this.pos,this.level,this.state,this.i);
                this.kill();
            }

            this.setDeltaMovement(this.vec.add(0 , 0.5, 0));

                this.move(MoverType.SELF , this.getDeltaMovement());

                ++this.time;

    }

    //places block after moving the entity
    void placeBlock(BlockPos pos, @NotNull ServerLevel level , BlockState state , int i)
    {
            level.setBlock(pos,state , i);
    }
}

I figured it was better to make a FallingBlockEntity than a fireball. But still I can't figure out how to change the blockState . I looked at FallingBlockRenderer but I don't know how to use it.

You can't do it like that. If you want to subclass the FallingBlockEntity you need to create your own EntityType.

I am not even sure the FallingBlockEntity is even designed to be subclassed?

There is a "smart constructor" where you can create a FallingBlockEntity from a BlockState see FallingBlockEntity.fall()

and ScaffoldingBlock.tick() for example usage.

 

But I thought you just wanted to render a block when drawing your entity? FallingBlockRenderer is just an example of this.

The basics of what it is doing is this pseudo code:

// Get the BlockState from the FallingBlockEntity
BlockState blockstate = fallingBlockEntity.getBlockState();

-- snip --

// Get the model for that block state and render each render type
var model = this.dispatcher.getBlockModel(blockstate);
for (var renderType : model.getRenderTypes(....))
     this.dispatcher.getModelRenderer().tesselateBlock(...);

You would probably just hard code the blockstate with something like Blocks.GRASS_BLOCK.defaultState() ?
