Hello everyone, I have made a custom potion effect; however, I haven't the slightest clue as to which methods to use to add a texture to the potion effect in the player's inventory GUI.

 

Does anyone know how to render textures for potion effects?

 

Thank you!

 

Here is my CustomPotion class

package eclipse.MoreApples.potion;


import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.texture.TextureManager;
import net.minecraft.client.renderer.texture.TextureObject;
import net.minecraft.client.resources.ReloadableResourceManager;
import net.minecraft.client.resources.Resource;
import net.minecraft.client.resources.SimpleReloadableResourceManager;
import net.minecraft.potion.Potion;
import net.minecraft.src.ModLoader;
import net.minecraft.util.ResourceLocation;

public class CustomPotion extends Potion {


public CustomPotion(int par1, boolean par2, int par3) {
super(par1, par2, par3);


}

public Potion setIconIndex(int par1, int par2) {

//(3,2) is where I drew my texture in the "2D array" of textures in the inventory.png
super.setIconIndex(3, 2);
return this;
}

@Override
public int getStatusIconIndex() {

ResourceLocation r = new ResourceLocation("textures/gui/container/inventory.png");

TextureObject texture = Minecraft.getMinecraft().renderEngine.func_110581_b(r);
Minecraft.getMinecraft().renderEngine.func_110577_a(r);
return super.getStatusIconIndex();

}
}

 

Here is my inventory.png picture

What I Want to Happen: My custom potion effect to show up in my player gui with my custom texture

What is Going On Right Now: The potion effect is working correctly, but the texture shows up as a box with yellow/blue corners. I noticed this was the empty space in the original inventory.png file, but I created a new inventory.png with that space filled in.

Hi

 

I've never done what you're looking for but I think this link might help you to understand the concepts

 

http://greyminecraftcoder.blogspot.com.au/2013/08/rendering-inventory-items.html

 

The bit you are probably interested in is

RenderItem.renderItemIntoGUI, about halfway down -

look for requiresMultipleRenderPasses() and hasEffect().

 

Some of your comments make me think you might not have heard of alpha channel before?  Your item images need to have alpha channel information so that Minecraft knows which part of the image is transparent.

Thanks for the quick reply.  However, I looked at this blog and it describes how to render Items into the player's GUI. I however need to just simply tell the game to look at a certain spot in the inventory.png file and display that image into the GUI. I am getting a potion effect icon except it is blank(except for the blue/yellow) corners. I checked my file to make sure it had transparency, and it did. My problem, I think, arises from these lines of code:

 

 

	
ResourceLocation r = new ResourceLocation("textures/gui/container/inventory.png");

TextureObject texture = Minecraft.getMinecraft().renderEngine.func_110581_b(r);
Minecraft.getMinecraft().renderEngine.func_110577_a(r);

 

I just need to find away to tell Minecraft to find my .png file. and to register it with the game.

Use your own texture.

new ResourceLocation("mymodname","mytexture.png");

I do. I created a copy of inventory.png and replaced the empty spot with a texture.For some reason, it is loading a deafult empty texture space, even though I made my own texture sheet.

You have to change the texture path. 

I put the texture in the right place and gave the ResourceLocation the same address : textures/gui/container/inventory.png

 

Although, I have to agree with you that this is weird. I gave setIconIndex(int par1, int par2) coordinates that match the jump boost icon and my custom potion effect texture rendered as the jump boost icon. However, when I switched the coordinates, it went back to the bank spot, even though I triple-checked that there was a texture there.

 

Also, my full file path is C:\Users\ItsTheRuski\Dropbox\Modding\More Apples\forge\mcp\src\minecraft\assets\more_apples\textures\gui\container\inventory.png

 

Is that filepath correct?

 

Thanks, again! =)

Hi

 

I would suggest: change your inventory.png to a test texture (for example draw some diagonal coloured stripes over your existing inventory.png) and see what renders.  Your blank spot might not be where you think it is.

 

Might also be worth setting a breakpoint just before the code that renders your potion effect, then trace it through to see why it works for  jump boost and not for your intended icon.

The file path don't match, it should be ResourceLocation("more_apples","textures/gui/container/inventory.png")

THANK YOU SO MUCH! GotoLink, your advice worked! I realized now that I have an extra folder, so I need to specify. Thanks again to both of you for helping! =)
