Hi there!

 

I have this problem where my arrow entitys render as a purple arrow.

I have registered the arrow but it's not working.

You need to bind the texture between the GL11.glPushMatrix(); and GL11.glPopMatrix() method.

Does not matter where you bind the texture (as long as it's before the texture drawing)

 

1. Why do you have an Icon in your render file? It does not belong there.

2. Can we see how you registered your Arrow entity (and the render)?

Client Proxy:

package extendedobsidian.atheera.com;

import cpw.mods.fml.client.registry.RenderingRegistry;
import cpw.mods.fml.common.registry.GameRegistry;

public class ClientProxy extends CommonProxy{

@Override
public void registerRenderThings() {

	GameRegistry.registerTileEntity(TileEntityFusionFurnace.class, "tileentityfusionfurnace");
	RenderingRegistry.registerEntityRenderingHandler(EntityObsidianInfusedArrow.class, new RenderObsidianInfusedArrow());

}

public int addArmor(String armor) {
	return RenderingRegistry.addNewArmourRendererPrefix(armor);
}

}

 

I forgot this also:

Main class

 

EntityRegistry.registerModEntity(EntityObsidianInfusedArrow.class, "ObsidianInfusedArrow", 2, Core.instance, 128, 1, true);

LanguageRegistry.instance().addStringLocalization("entity.ObsidianInfusedArrow.name", "Obsidian Infused Arrow");

 

EntityRegistry.registerGlobalEntityID(EntityObsidianInfusedArrow.class, "ObsidianInfusedArrow", EntityRegistry.findGlobalUniqueEntityId());

The only thing left is now the class where you register the entity itself.

Isn't that done in the bow class?

No, within the bow class, you only instantiate it.

You need to register the entity class like any other entity.

I have this in the init of my main class

 

EntityRegistry.registerModEntity(EntityObsidianInfusedArrow.class, "ObsidianInfusedArrow", 2, Core.instance, 128, 1, true);

LanguageRegistry.instance().addStringLocalization("entity.ObsidianInfusedArrow.name", "Obsidian Infused Arrow");

 

EntityRegistry.registerGlobalEntityID(EntityObsidianInfusedArrow.class, "ObsidianInfusedArrow", EntityRegistry.findGlobalUniqueEntityId());

 

Shouldn't that do it?

the registerGlobalEntityId is not needed, you can omit that.

Can you do a System.Out.Println("renderme"); in your doRender method and see if it gets called?

Yeah, it gets rendered alright:

I might see the problem, you're getting an arrow with a missing texture icon, because of this:

new ResourceLocation(Core.modid.toLowerCase() + ":ObsidianInfusedArrowEntity")

 

You can't use the ResourceLocation the same way as you would register icons (since they not only handle textures, but also sounds etc.)

To use it properly, you have to specify a path to the file (with extension), so like:

new ResourceLocation("baseFolder:textures/entity/myArrow.png")

where baseFolder is the folder in the assets folder (here your mod id) and textures/entity/myArrow.png the path to the texture file:

assets/baseFolder/textures/entity/myArrow.png

OMG! I love you so much! THANK YOU!!

Well, the texture is rendering correctly, although... The arrow gets stuck in mid-air.

does it get stuck after it hits something or during flight?

Another question is what does your EntityArrow do different from the vanilla one? I see a lot of copied code. Can't you just extend the vanilla one and make your changes?

Here's an example from my arrow entity: https://github.com/SanAndreasP/EnderStuffPlus/blob/master/java/de/sanandrew/mods/enderstuffplus/entity/EntityAvisArrow.java

I am uploading a video now, but when it has hit something, it goes back a bit.

I want it to act exactly like the vanilla arrow but do more damage.

Arrows behaving themselves weird

If you just want more damage then you can definitely just extend the vanilla arrow entity in fact if you wernt doing custom rendering you wouldn't have to make your own arrow at all (you can modify the damage coursed by a vanilla arrow when you spawn it)

Just dont forget to remove the fields:

public int canBePickedUp;

public int arrowShake;

and

public Entity shootingEntity;

Or you will get the common "Arrow hits shooter" problem

It is also a good idea to replace super.onUpdate() in the onUpdate method with

super.onEntityUpdate(); otherwise both the onUpdate from the vanilla arrow and you custom onUpdate method will run and you probably dont want this.

I have gotten the texture right and the arrow behaving as I want them to, but the damage is wrong, and I don't know how to fix it.

You don't reference the

damage

field you've declared.

Actually you don't even need to.

 

I recommend just to override setDamage and call the super method with the given parameter multiplied by the value, meaning it has x times more damage than a vanilla arrow would've.

 

Also remove the getDamage method and the damage field

I have tried everything but nothing works. There doesn't seem to be any tutorials online to fix it either.

Again, remove the damage field in your class! It's not referenced anywhere and unlike methods, fields cannot be "overridden"!

Also do your calculations before the super method call, and only on the local variable. Also a tip, you can also do

damage *= 3.0D

, which basically says "re-assign the variable with itself multiplied by 3.0D". You can also use this on any numerical type with any mathematical or bitwise operator.

But what you can also do is to do the calculation within the parameter assignment like

method(variable * [value])

Hey man, I got it working with damage and everything.

I hope you don't mind me using your class.
