Three Icon problems

TrekkieCub314 · April 10, 2015

So, I seem to be having some problems when it comes to Icons.

1: I have a machine that renders the icon of the fluid it contains, but this is only working for vanilla fluids. I have one custom fluid created so far, but when I try to render the icon, I get a NullPointer Exception, and where it's being called from is telling me that I'm getting a null value for the still icon in the fluid. I rearranged my main mod file to see if the problem was in the order I was instantiating the blocks/fluids and registering them, but that didn't seem to work (unless I messed that up)

2: Because I am using a custom renderer, I'm not sure how to go about rendering the icon for the block while in the inventory. Currently it's using the block's top face, but I'd like it to render like a furnace might.

3: I am using a GUI for my block that renders the icon of the fluid as a large box in the center of the gui, but I also wanted to have the graphic for an item slot appear on top of that. As such, I rendered the fluid, then the graphic on top of that. Unfortunately, when working, the icon for the item I place in the slot disappears as it's being rendered over by the fluid and the graphic. I was thinking about getting the icon for the item in the appropriate slot from the tile entity that was passed in, but I can't get further than getting the item. I'm not sure how to get the icon from the item, and the item passed in can either be a regular Item or an item obtained from a Block.

You got a crash, which is a Null Pointer, and you didn't bother including the crash report.

You got a crash, which is a Null Pointer, and you didn't bother including the crash report.

I didn't include a crash report because this isn't the first time I've programmed and I know how to parse error messages. A NullPointer exception comes up when trying to use a method or access a property of a field which isn't instantiated or is set to null. Hence why I explained where the error is coming from in the OP.

But if you want the crash report, here it is:

Ok, from that, I get the following:

java.lang.NullPointerException: Unexpected error something was null
at net.minecraft.client.renderer.RenderBlocks.renderFaceXNeg(RenderBlocks.java:7652) here's the line the null object was referenced, not "my" code, but...

at com.trekkiecub.allthethings.Render_Immersion_Tank.renderWorldBlock(Render_Immersion_Tank.java:37) Ah, this line passed a null object to RenderBlocks

Looking at Render_Immersion_Tank.java line 37, I see the call to renderFaceXNeg.

renderer.renderFaceXNeg(block, x, y, z, newIcon);

Only two things could possibly be null here:

block

or

newIcon

. My bet is on

newIcon

.

Insert some debug statements to figure out which path through your if statement the code is taking and what value

newIcon

has at each step. Work backwards until you figure out where the null is coming from and why.

java.lang.NullPointerException: Unexpected error something was null
at net.minecraft.client.renderer.RenderBlocks.renderFaceXNeg(RenderBlocks.java:7652) here's the line the null object was referenced, not "my" code, but...

at com.trekkiecub.allthethings.Render_Immersion_Tank.renderWorldBlock(Render_Immersion_Tank.java:37) Ah, this line passed a null object to RenderBlocks

Looking at Render_Immersion_Tank.java line 37, I see the call to renderFaceXNeg.
renderer.renderFaceXNeg(block, x, y, z, newIcon);
Only two things could possibly be null here:
block
or
newIcon
. My bet is on
newIcon
.

Insert some debug statements to figure out which path through your if statement the code is taking and what value
newIcon
has at each step. Work backwards until you figure out where the null is coming from and why.

It couldn't be block. The error starts in the RenderBlocks class, at this line:

double d3 = (double)p_147798_8_.getInterpolatedU(this.renderMinZ * 16.0D);

The only thing that could be null in this case is the p_147798_8, which is the IIcon passed into the function renderFaceXNeg. A null value had to be passed into the renderFaceXNeg function.

Looking back at the Render_Immersion_Tank file, we see the icon is set to the icon of water when it is created. I then check some conditions to see if I should render a default face instead of a liquid. The only other change that occurs with the icon is when that if statement doesn't go through and it falls to the else statement below. Since there was no null pointer error here, the tile entity, its FluidTank, and that FluidTank's fluid were not null. The only place the null value could come from was the getStillIcon() function.

Looking back at the fluid file, the getStillIcon() function calls the getIcon function, with parameters passed to ensure the flowing icon gets returned. The only way to get a null value out of that is if the getStillIcon() function is being called before the registerBlockIcons function, and I'm not sure how that is happening. Changing the getStillIcon function to get the stillIcon item directly doesn't help.

Again, you're going to have to insert some debug statements to determine the cause. I can't give you any more help from here.

Two of the three problems are now solved:

To render the custom fluid correctly, instead of calling getFluid().getStillIcon, I used getFluid().getBlock().getBlockTextureFromSide(0) and it worked for both the gui and the block renderer.

The icon for the block was mostly copy-paste from RenderBlocks.renderBlockAsItem() with the metadata being passed in being modified with the corresponding block's getIcon() function being modified to accommodate.

I am still unsure how to render the icon for the item being processed on top of the fluid and item slot I'm rendering when the block is updated.
