How would I go with making a texture for an EntityThrowable? I want to add a dagger that can be thrown, I have done that but it doesn't have a texture. I bet there's a Forge hook for this, could anybody show me an example?

Anyone? Just how would you add a custom snowball?

I'd suggest you make your own render file similar to RenderArrow.

If you don't mind how silly your dagger entity would look with the standard throwable renderer, just use RenderSnowball.

Yea well the thing is I don't know how to change the texture file, do you?

Use RenderFireball code, I think it's simpler.

 

        Icon icon = Item.fireballCharge.getIconFromDamage(0);
        this.loadTexture("/gui/items.png");
        Tessellator tessellator = Tessellator.instance;
        float f3 = icon.getMinU();
        float f4 = icon.getMaxU();
        float f5 = icon.getMinV();
        float f6 = icon.getMaxV();

 

Replace the icon with what You need. Or You could use Techne, there are some tutorials I may recommend.

You would also require another tutorial, on how to use Techne generated code to render entities. I've been using it to render items so far.

Use RenderFireball code, I think it's simpler.

I used the fireball code, but it still doesn't render. Here's my code:

	tessellator.draw();
	GL11.glDisable(GL12.GL_RESCALE_NORMAL);
	GL11.glPopMatrix();
}

@Override
public void doRender(Entity par1Entity, double par2, double par4, double par6, float par8, float par9)
{
	doRenderFireball((EntityFireball)par1Entity, par2, par4, par6, par8, par9);
}
}

 

 

ClientProxy:

 

 

package me.raggarcowboy.silverdagger;

import net.minecraftforge.client.MinecraftForgeClient;
import cpw.mods.fml.client.registry.RenderingRegistry;

public class ClientProxy extends CommonProxy
{
@Override
public void registerRenderers()
{
	MinecraftForgeClient.preloadTexture("/textures/items/Silver_Dagger.png");

	RenderingRegistry.registerEntityRenderingHandler(EntitySilverDagger.class, new RenderSilverDagger(1F));
}
}

 

 

Questions:

• What does the float parameter in the RenderSilverDagger constructor do?
  
• Do I need to register anything more?
  
• Is there anything more you'd recommend?
  

Well, if it rendered, It would crash, as You cannot cast EntityDagger into EntityFireball in doRenderFireball. Change types used in method.

 

Second: in EntitySilverDagger class, you have to define a constructor, which takes only world as parameter. Even if You don't use it anywhere, rendering functions still need it.

 

Thirdly, you'll need also to register EntityID in EntityRegistry

 

//RegisterRenders is a fine place for this line
EntityRegistry.registerGlobalEntityID(EntitySilverDagger.class, "SilverDagger", ModLoader.getUniqueEntityId());

 

And register entity in Your load method

 

EntityRegistry.registerModEntity(EntitySilverDagger.class, "SilverDagger", 1, instance, 160, 1, false);

 

Does it work now?

 

The float is not needed. Remove it.

I'm really sorry about all these questions but I really just want to add a simple snowball with another texture. Now, I followed your steps provided here and I got it to render! but it renders as a white cube flying in the air, I don't want it like a cube, I just want the texture flying in the air... If I remove the float, then I'll have to remove these two lines of code:

float f2 = this.field_77002_a;
GL11.glScalef(f2 / 1.0F, f2 / 1.0F, f2 / 1.0F);

It doesn't change anything so I wonder if you know what they do? Also since it doesn't render any texture, I can guess that I've put a wrong path in it. Is this correct?

Icon icon = SilverDagger.swordSilver.getIconFromDamage(0);
loadTexture("/mods/silverdagger/textures/items/Silver_Dagger.png");

Or should I change the path somehow? Thank you so much for this help

I have a similar problem as well i have a throwable snowball with a rock in it i just wanted it to look like a snowball ? it currently renders as a white cube as well, i hope you find a way to solve this soon

I'm not sure if it will work for You  - it worked when I tried some tests myself, but then You may be missing some code I'm not aware You don't have.

 

loadTexture("/mods/silverdagger/textures/items/Silver_Dagger.png");

This should rather stay

 

this.loadTexture("/gui/items.png");

 

Important is that

 

Icon icon = SilverDagger.swordSilver.getIconFromDamage(0);

 

Try it. Now, if it works, further explanation is not necessary.

 

If not:

 

1. Delete (or better comment, using ctrl+/ shortcut) the whole render code (I mean doRender function), leaving it

an empty function.

 

2.Try to run it - if

a) it still renders like white cube, that would mean that

Your render code isn't even used. You would have to double check render registering, for example using

 

the tutorial I provided. Part II and part III contain info about rendering.

 

b) the entity simply doesn't show, that the thing that needs checking is if Your getIconFromDamage returns initialized Icon. You may need to move item registration to preInit method if it doesn't.

cant you just post you working code?

and you use modloader. in your tutorials which makes the mod non smp compatible

I'm not sure if it will work for You  - it worked when I tried some tests myself, but then You may be missing some code I'm not aware You don't have.

I got it to work! The problem was in the render registration, I registered it in the registerRenderers method in ClientProxy.java at first, but then I tried to do it in the load method and it worked! Do you know why it didn't work in ClientProxy? I did initialize it in the main class...

 

Btw, I read some of the tutorial you provided, that seriously is a really great tutorial! I will definitely use it in the future! Thanks a lot

please post our working code, PLEASE!...

I'm glad that I helped You, Raggarcowboy.

 

As for You, ashtonr12:

 

and you use modloader. in your tutorials which makes the mod non smp compatible

 

Hm. I use it in my mod as well, and it works in multi, doesn't crash server. Are You sure that it causes issues?

 

As for code, this works fine. The example item is thrownItem and entitythrownitem.

I would go ahead and follow Senitiels code, however if it still doesn't work, the part that fixed it for me was switching place of...

RenderingRegistry.registerEntityRenderingHandler(EntitySilverDagger.class, new RenderSilverDagger());

from ClientProxy.java to your load/init-method in your main mod-class, like so

@Init
public void load(FMLPreInitializationEvent event)
{
     RenderingRegistry.registerEntityRenderingHandler(EntityBlasterBolt.class, new RenderBlasterBolt());
}

Good luck!

ok so i added and followed the tutorials twice but the entity doesnt seem to render, i have it so that its basiccaly exactly the same as a snowball, i think i must have missed a line of code whne i right click the RockSnowball is consumed (good) but the entity doesnt show(bab) but when i shoot it at water i can hear it splash (good) so its obvoisely there but not rendering also nothing happens when i shoot it at living entities such as cows.

why these problems?

Well, You were supposed to use RenderThrownItem it as the body for

 

private void doRenderRockSnowball(EntityRockSnowball par1Entity, double par2,
	double par4, double par6, float par8, float par9) {

}

 

Remember, there's no magic here - if a method isn't called anywhere, then it won't do anything. You may check it using Eclipse right click->show references

i was meant to use what as what?

did you mean this part?

public void doRenderRockSnowball(EntityRockSnowball par1EntityRockSnowball, double par2, double par4, double par6, float par8, float par9)
{

i missed some words there but now it just shoots a white square that does not interact with the world

i was meant to use what as what?

Seems as your code has quite a lot of flaws... First of all, instead of "this.setDead();" in onImpact in your EntityRockSnowball class, use this code:

 

 

if (par1MovingObjectPosition.entityHit != null)
	{
		par1MovingObjectPosition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), ; // <-- change 8 to whatever damage you'd like to cause
	}

	if (!this.worldObj.isRemote && this.rand.nextInt( == 0)
	{
		byte b0 = 1;

		if (this.rand.nextInt(32) == 0)
		{
			b0 = 4;
		}
	}

	for (int j = 0; j < 8; j++)
	{
		this.worldObj.spawnParticle("snowballpoof", this.posX, this.posY, this.posZ, 0.0D, 0.0D, 0.0D);
	}

	if (!this.worldObj.isRemote)
	{
		this.setDead();
	}

 

 

That will damage the target and also spawn a snowball particle. You can change the number I've commented by to change the damage.

Second of all, in the doRenderThrownItem, replace...

this.loadTexture("ashtonsmod:RockSnowball");

... with...

this.loadTexture("/gui/items.png");

Third thing, inside the doRender function, put doRenderThrownItem(etc...) instead of doRenderRockSnowball(etc...) since this function is completely empty. Also you can delete the doRenderRockSnowball function (the last function of the render class) since it only takes unnecessary space.

 

Now if all of this still doesn't work, then take away the RenderingRegistry.registerEntityRenderingHandler(EntityRockSnowball.class, new RenderRockSnowball()); line from your ClientProxy and put it in the load/init function of your main class.

 

Hope this helped

Yes this works thankyou alot!
