Hello

 

I have an Entity, that needs a Layer-class to show a transparent part (like the vanilla-Slime).

I have the Model-class, the Renderer-class, the Layer-class and the Model-class.

In all of them the class-header, the header of the constructor and the superconstructor-call (if exist) have the same shape like in the Slime-classes, i just use the classes for my own entity, where.the Slime-classes where used.

So i wonder, why i get an error:

Quote

Cannot infer type arguments for CoralFinLayer<>

at this line in the Rendererclass:

this.addLayer(new CoralFinLayer<>(this));

 

Entity-class:

/** 
 ** This is Coral, an angler-fish-character from a not so well known Rovio-game called "Fruit-Nibblers".
 ** I added her here, because her game is from the creators of Angry Birds, too.
 ** I like her look and I think, it maybe a good idea to make her best friends with Stella

Does it matter, that my Entity extends AnimalEntity, while the Slime extends MobEntity?

}

I´m pretty sure, that it doesn´t matter, wich input-type i use in the constructor of the model to separate the maln-parts and the layer-part.

Now i noticed, that i get no more error, if i remove the "<>" in the line, that has shown the error.

But it makes "rawtypes" and "unchecked" warnings.

So i wonder, why i cannot use the "<>"  like shown in the slime...

 

Now it renders the fin transparent, but stained glass blocks behind it appear invisible (in opposite order i can see the semi-transparent pixels of the fin throuch transparent blocks)...

 

You can see the ground and bodyparts of the entity through the fin, but not the edge of the glassblock at the top of the fin.

The scene is taken through another glassblock to show, that in the other order the transparencys work fine

 

How kan i make it able to show the transparencys in both directions correct?

Learn Java basics: this was generics.

CoralModel<T extends Entity> extends SegmentedModel<T>

Your EntityModel need a Type (T was standing for Type, see Generics, and yes, the Characters you use are important, you can‘t use a character that dosen‘t match with Generics Char.), the Type that your Model class need was your entity or something else: i recommend you to remove the <T extends Entity> part and insert in the place of SemgentedModel<T> SemgentedModel<CoralEntity>, @Drachenbauer.

 

Then i am curious: How do you have make that your entity now have semi-transparent parts? Can you say it, this can help further people. And pls say it to your other topic:
