I have subclassed BlockHopper now I need to render my hopper. How?

[ILuvYouCompanionCube]

I have a block that looks exactly like a hopper except for the textures. How do I make my hopper show the correct textures? I managed to make it show the _top and _outside textures using reflection (my textures are just like the ones from the original hopper, but with different colour), but from what I could understand, _inside texture is referenced only inside a method of the RenderBlocks class called renderBlockHopperMetadata, exactly at this line:

 

Icon icon1 = BlockHopper.getHopperIcon("hopper_inside");

 

And that's my problem. That line is invoking a static method. For obvious reasons I can't override a static method (even though I think java should allow that since it's the only language I know where you can access a static member using an instance, like:

 

SomeClass instance = new SomeClass();
instance.SomeStaticMethod(); //this line is one of the top 10 reasons of why java sucks IMO.)

 

and here's the BlockHopper static method:

 

@SideOnly(Side.CLIENT)
public static Icon getHopperIcon(String par0Str)
{
        return par0Str.equals("hopper_outside") ? Block.hopperBlock.hopperIcon :
               (par0Str.equals("hopper_inside") ? Block.hopperBlock.hopperInsideIcon : null);
}

 

What can I do? Basically, all I need to do is change the color of the hopper, nothing more, like tinge it a little. Is there a way to do that? Thanks

I am thinking that you could try using a GL11.glSomethingOrOtherThatDealsWithOverlayRGBA(Red, Green, Blue, Alpha); somewhere to change the color of only your Hopper... Since I am guessing your hopper extends the other one, couldn't you also just override the method? Or is it in another class?

[ILuvYouCompanionCube]

the method that renders the hopper is in another class called net.minecraft.client.renderer.RenderBlocks. And that same class has a method (named renderBlockHopperMetadata) which is called for rendering the hopper. That method in renderBlockHopperMetadata "asks" the hopper for it's icons, but the method it invokes is static (so I can't override it), and it invokes it like this:

 

Icon icon1 = BlockHopper.getHopperIcon("hopper_inside");

 

getHopperIcon does the following:

 

@SideOnly(Side.CLIENT)
public static Icon getHopperIcon(String par0Str)
{
        return par0Str.equals("hopper_outside") ? Block.hopperBlock.hopperIcon :
               (par0Str.equals("hopper_inside") ? Block.hopperBlock.hopperInsideIcon : null);
}

 

so my derived class is left out... And I know nothing of the other thing you said oO GL11 what

Do you have a github/bitbucket we could look at, so we can just look at any code we need to look at?

no and there's actually a good for that but its kinda long to explain (or i suck at explaining things)

 

cant you just override the icons with the one you want and copy the cope to render the hopper in a ISBRH ?

[ILuvYouCompanionCube]

The icons are overriden with the ones I want on my class (which are the same, but slightly tinged golden), but as you can see in the code I posted, renderBlockHopperMetadata calls a static method of BlockHopper, which uses the static instance of BlockHopper owned by the Block class (Block.blockHopper). If I ovewrite the textures of BlockHopper, my Hopper will work, but the vanilla Hopper will look just like mine.

 

I don't know what is a ISBRH. Could you explain that?

I don't have it and I don't even know what it is, sorry.

ISBRH = ISimpleBlockRenderingHandler, check the wiki theres a tutorial on it

[ILuvYouCompanionCube]

I'm working on it, hydroflame, but I have a doubt: I only need to override renderWorldBlock? Not overriding the other methods of the interface won't cause any problems under specific circumstances?

[ILuvYouCompanionCube]

no and there's actually a good for that but its kinda long to explain (or i suck at explaining things)

 

You mean there is a good reason why I can't override static methods? (If that's it, I know there is one. It does't even make sense from a OOP point of view, and it would also break the virtual machine since static methods are invoked differently with a different OPcode).

 

But if you mean there is a good reason why I can do this in java, please let me know:

Integer aNumber;
aNumber.parseInt("1000");

 

Calling a static method on an instance is confusing. People would assume aNumber has the value 1000 now, but it doesn't, The static method doesn't even know aNumber exists.

yeah

it worked! thanks
