[1.7.10] [UNSOLVED] How to use a semi-transparent item texture


Silly511

Recommended Posts

I have a item that uses a semi-transparent texture, however the texture is only semi-transparent in the inventory, not in my hand or on the ground. I know I need to make custom Item Renderer and enable GL_BLEND. I've made a item renderer but what do I put in it to render the item normally, but with GL_BLEND enabled? Here is my current IItemRenderer:

 

@SideOnly(Side.CLIENT) 
public class SemiTransparentRenderer implements IItemRenderer {

private Item item;

public SemiTransparentRenderer(Item item) {
	this.item = item;
}

@Override
public boolean handleRenderType(ItemStack item, ItemRenderType type) {
	if (type != ItemRenderType.INVENTORY) {
		return true;
	} else {
		return false;
	}
}

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

@Override
public void renderItem(ItemRenderType type, ItemStack item, Object... data) {
	GL11.glEnable(GL11.GL_BLEND);



	GL11.glDisable(GL11.GL_BLEND);
}

}

Ok, so I got most of it to work. The transparent texture now works perfectly, but for some reason when I pick the item up, it briefly turns white. Why would it do that? Here is my new code:

 

@SideOnly(Side.CLIENT) 
public class SemiTransparentRenderer implements IItemRenderer {

@Override
public boolean handleRenderType(ItemStack item, ItemRenderType type) {
	return type != ItemRenderType.INVENTORY;
}

@Override
public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item, ItemRendererHelper helper) {
	return helper == ItemRendererHelper.ENTITY_BOBBING || helper == ItemRendererHelper.ENTITY_ROTATION;
}

@Override
public void renderItem(ItemRenderType type, ItemStack item, Object... data) {
	IIcon icon = item.getIconIndex();
	Tessellator tessellator = Tessellator.instance;

	GL11.glPushMatrix();

	if (type == ItemRenderType.ENTITY) {
		GL11.glTranslatef(-0.5F, -0.25F, 0.0F);
    }

	GL11.glEnable(GL11.GL_BLEND);
	ItemRenderer.renderItemIn2D(tessellator, icon.getMaxU(), icon.getMinV(), icon.getMinU(), icon.getMaxV(), icon.getIconWidth(), icon.getIconHeight(), 0.0625F);
	GL11.glDisable(GL11.GL_BLEND);

	GL11.glPopMatrix();
}

}

@Override

public boolean handleRenderType(ItemStack item, ItemRenderType type) {

if (type != ItemRenderType.INVENTORY) {

return true;

} else {

return false; *true

}

}

 

I'm new to coding so sorry if i'm wrong but... Your telling it to only render if the render type is the player's inventory, not anywhere else? Switch this* to true I think.

!= means if type is not equal to inventory and == means if type is equal to inventory. So

 

if (type != ItemRenderType.INVENTORY) {
         return true;
      } else {
         return false;
      }
}

 

Means that if type is not equal to inventory then return true, else return false.

If we already discuss this piece of java code, you should consider the oracle java code conventions paragraph 10.5.2

That states:

if (type != ItemRenderType.INVENTORY) {
         return true;
      } else {
         return false;
      }
}

should be written as

return type != ItemRenderType.INVENTORY;

 

Also i am sorry that i cannot help you with your problem, but anyway in 1.8 IItemRenderer  is deprecated/removed (depending on which version of forge you use)

    • Crash with the error: The game crashed whilst exception ticking world Error: java.util.ConcurrentModificationException pastebin crashlog the game worked for like 24h, then started to receive this error. Things I've tried: removing optifine or other performace mods. tried different versions (older) of the pack. set true to remove error entities and tiles in forge.cfg asked for help on the sevtech github, they said its fixed, its not. tried a different pc and still crashed happened only one time on another map although i cant make it happen again on that map.

    • I am in such a mess. I have lost over 4.7m due to a scammer... It started as bank wires and then bitcoin. it is hard to imagine but it is true and can send any proof, then I tried to use a couple of recovery companies and was as well. Graphic design has been more than just a hobby for me since high school—it has become a thriving career. Starting in my parents' garage, I eventually expanded to my office, running a successful graphic design business. However, like many, I faced the need to diversify my investments due to inflation. This led me to invest 60.16 in Bitcoin, a decision that paid off handsomely as my investment grew to 4.7m over time. This financial windfall allowed me to upgrade my equipment and take on more ambitious projects, furthering the growth of my business. Unfortunately, my excitement was abruptly cut short when I fell victim to a hacking incident. Malware infected my computer, giving hackers access to my Bitcoin wallet. The devastation of potentially losing all my hard-earned savings and plans weighed heavily on me. At this dire moment, a fellow designer suggested Linux Cyber Security Company as a potential solution. Desperate for a lifeline, I reached out to them, hoping for a miracle. The response from Linux Cyber Security Company was prompt, incredibly professional, and effective. Their team quickly traced the hacker’s activities and recovered most of my funds, alleviating a significant amount of stress and uncertainty. Beyond the recovery, they took the time to educate me on essential practices to secure my Bitcoin holdings better. They emphasized using antivirus software to prevent malware infections, avoiding suspicious downloads, and the added security provided by hardware wallets. This experience served as a critical wake-up call for me. It highlighted the vulnerabilities inherent in digital assets and underscored the importance of robust security measures. Thanks to the guidance and expertise of Linux Cyber Security Company, I now feel more equipped to protect my digital assets proactively. Their insights have empowered me to implement stronger security protocols in my business operations and personal finances alike. With my Bitcoin funds securely recovered and a newfound understanding of digital security best practices, I am more confident in navigating future challenges. This journey has reinforced my commitment to safeguarding my hard-earned assets and leveraging technology responsibly. I am optimistic about the growth opportunities ahead, creatively in graphic design and prudently in investment strategies. In conclusion, while the hacking incident was a setback, it ultimately became a catalyst for enhancing my digital security awareness and resilience. I am grateful to Linux Cyber Security Company for their expertise and support during a challenging time, enabling me to continue pursuing my passion for graphic design with renewed confidence and financial stability.
