[Unsolved] 3D Item Renderer Weirdness

chimera27 · September 22, 2013

I've been trying to get an item from my mod to render with a nice 3D model, but after repeated attempts all i'm getting is this error:

And the only relevant thing in my main is that i'm registering my renderers through my clientproxy in my preinit

Anyone know what i'm doing wrong here?

Kakarotvg · September 22, 2013

try changing

protected ModelPowerBeam powerbeamModel;

to

private ModelPowerBeam powerbeamModel;

and try using the latest version of forge instead of the recommended version from here

http://www.files.minecraftforge.net

in the latest versions func_110577_a was replaced with bindTexture so try using that, as well as what I said above about the private, if it still doesn't work let me know.

TheGreyGhost · September 22, 2013

Hi

The error appears to be occurring in your ModelPowerBeam constructor, so have you tried stripping the constructor down to something very simple (or even empty) and then adding the statements back in, one by one? Or setting a breakpoint in the constructor? Perhaps you have initialised one of the shapes in the wrong order?

(BTW - in Java it would generally be considered best practice to call your variables shape1 not Shape1 etc).

EntityRegistry.registerGlobalEntityID(EntityIceBolt.class, "IceBolt",
			EntityRegistry.findGlobalUniqueEntityId());

Why are those registered on client side in registerRendering() ?

chimera27 · September 22, 2013

Changing it to private didn't change anything related to the error, and the model was made via techne, so the function names and such were generated by it, also I put the entity and renderer registries in my clientproxy because that's what I saw to do in the tutorial on making them... I'm gona try updating forge because that might help but i'm fairly certain that Minecraft.getMinecraft().renderEngine.func_110577_a(new ResourceLocation(

isn't even being called because it crashes first

Edit: Anyone know where a list of the new names for functions is for 1.6.4? 'Cause it's a bit hard to discern what things like func_110775_a were supposed to be doing......

Edit Edit: Nevermind, managed to discern them!

chimera27 · September 22, 2013

Just tried updating, didn't change anything I honistly have no idea what's wrong, gona try // ing some of the lines in my modelpowerbeam class to see if it helps anything but i'm still fairly certain that's not it because it was generated by techne and all the methods it calls exist and are used right as far as I can tell...

Dmitchell94 · September 22, 2013

I put the entity and renderer registries in my clientproxy because that's what I saw to do in the tutorial on making them...

Do you have a link to the tutorial because ive been trying to find a good one and have not been able to.

Follow the tutorials in forge wiki, not some random shi**y tutorial.

Dmitchell94 · September 22, 2013

and youve found a rendering tut in the forge wiki that is detailed. the one i saw was fairly basic and not really to clear

chimera27 · September 22, 2013

Ok I found the source of the crash, Shape16.mirror(); was being called thrice, once before Shape16 was fully initialized, buggy techne is buggy I guess Anyway, now there's a new issue, the model isn't rendering, it's just using the inventory sprite not the model...

Mew · September 23, 2013

That will probably be because you are not in the view that you specified in your render code

if you told it to only render the model in third person, it will only render in third person. If you tell it to only render the model in first person, it will only render in first person.

chimera27 · September 23, 2013

Herpdy Derp!! Thanks, probs never would have realized that... lol I feel like the kind of person that thinks they lost their sunglasses and then realizes they were wearing them the whole time right about now...

Also btw the tutorial that told me to register my entities in my clientproxy is a forge tutorial, its the making of a space marine mod or something like that, it was quite comprehensive....

Wait, wat. For whatever reason it's rendering facing the ground...... That's not how my techne model had it, i'm assuming rotation is something i'm supposed to specify myself somewhere isn't it.... anyone know what I would do that under?

Haha, thanks for the laugh mate! Sounds a bit like my Grandma... "Have you seen my glasses?", * I point to my eye *, * she puts her hand to her face and finds the glasses sitting on her nose * "Thank you dear".

chimera27 · September 23, 2013

Actually 2 more things are going wrong (could be one causing both)

First, it's being wielded like a sword, how would I go about changing the angle its wielded at? It's wielded right in 3rd person, but not first, even though the code is the same for both...

Second, the model pieces are segmented and spaced randomly as if they've been thrown around, here's a pic for refrence:

It's the same in 3rd person as 1st

Here's how it's supposed to look:

Just reading through this, and just incase the item not rendering in first person, the case you use is EQUIPPED_FIRST_PERSON in your item renderer class

I did that, my Itemrenderer is as follows (I should have posted this earlier):

package project.main.client;

import org.lwjgl.opengl.GL11;

import project.main.models.ModelPowerBeam;
import net.minecraft.client.Minecraft;
import net.minecraft.entity.Entity;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.client.ForgeHooksClient;
import net.minecraftforge.client.IItemRenderer;

public class ItemRenderer implements IItemRenderer {

private ModelPowerBeam powerbeamModel;

public ItemRenderer() {
	powerbeamModel = new ModelPowerBeam();
}

@Override
public boolean handleRenderType(ItemStack item, ItemRenderType type) {
	switch (type) {
	case EQUIPPED:
		return true;
	case EQUIPPED_FIRST_PERSON:
		return true;
	default:
		return false;
	}
}

@Override
public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item,
		ItemRendererHelper helper) {
	return false;
}

@Override
public void renderItem(ItemRenderType type, ItemStack item, Object... data) {
	switch (type) {
	case EQUIPPED: {
		GL11.glPushMatrix();

		Minecraft.getMinecraft().renderEngine
				.bindTexture(new ResourceLocation(
						"chimera27metroid:powerbeam.png"));
powerbeamModel.render((Entity)data[1], 0,0,0,0,0,0.0625F);
		GL11.glPopMatrix();
	}
	case EQUIPPED_FIRST_PERSON: {
		GL11.glPushMatrix();

		Minecraft.getMinecraft().renderEngine
				.bindTexture(new ResourceLocation(
						"chimera27metroid:powerbeam.png"));
powerbeamModel.render((Entity)data[1], 0,0,0,0,0,0.0625F);
		GL11.glPopMatrix();
	}
	case ENTITY: {
		GL11.glPushMatrix();

		Minecraft.getMinecraft().renderEngine
				.bindTexture(new ResourceLocation(
						"chimera27metroid/textures/models/powerbeam.png"));
powerbeamModel.render((Entity)data[1], 1,0,0,0,0,0.00F);
		GL11.glPopMatrix();
	}
	default:
		break;
	}
}

}

Hi

You might find this link useful, it shows the various coordinate transformations that Minecraft/Forge apply before calling your IItemRenderer, depending on the view. You'll notice that the zpos ("3") face often points in different directions from what you might expect.

http://greyminecraftcoder.blogspot.com.au/2013/09/custom-item-rendering-using.html

There's also another property for Items I didn't mention..

public boolean Item.shouldRotateAroundWhenRendering()

/**

* Returns true if this item should be rotated by 180 degrees around the Y axis when being held in an entities

* hands.

*/

I probs should have said this earlier, but last jight after playing around with it I finally managed to got it to go where i wanted it, but it's only visible when i'm in 3rd person! Te EXACT same rendering code is being called for first and 3rd person, and i did make sure to tell it to render it in first person this time! I can't post the code rigt now because i'm at school, but if anyone knows a general reason this would be the case it would be much appreciated!
