[1.7.10]GUI drawTexturedModalRect() bug or not working

[Enginecrafter]

I have a GuiScreen that shows a rectangle contained in texture file, but instedaded of showing rectangle it only shows a starange symblols like thaumcraft fonts.

 

Erroring GuiScreen:

GuiScreen#drawTexturedModalRect uses fixed rate for uv vs xy, so it wouldn't be useful as you think.

Instead, make your own method replacing that; Usually setting uv to 0~1 is appropriate.

[Enginecrafter]

I used it this way:

x - where I want to draw it on screen X

y - where I want to draw it on screen Y

u - position of rectangle in texture - X

v - position of rectangle in texture - Y

width

height

 

And, what do 0~1 mean? Did you mean I have to make a mathod where u and v will be always 0 and 1?

He means from 0.0D to 1.0D, a floating point number.

You need to calculate the u and v appropriate to the texture resolution you use, that means, u-position on texture is 16px, v-position is 32px, your texture is 128x64px:

u = 16 / 128 = 0.125D

v = 32 / 64 = 0.5D

[Enginecrafter]

What do you mean?

How can I do it? Is this method correct or I didn't understood it correctly?

 

Code:

[SanAndreaP]

If you look at Gui#drawTexturedModalRect, it multiplies u and v by a static value, fitting a texture of size 256x256.

If you want to draw a texture with a different size, you need to copy this method and adjust it to fit your texture resolution.

If you do have a texture using this resolution, you're fine to use it, but be careful that in this case u and v are the exact pixel values.

 

But your problem seems to be a different one: You don't bind your texture anywhere when drawing your rectangle, to do so, you need to call

this.mc.getTextureManager().bindTexture(TEXTURE_RESOURCE_LOCATION);

before you draw your rectangle.

[Enginecrafter]

I binded my texture in MainLib.createScreenBase(some parameters)

And, what is z-value?

[SanAndreaP]

1. Please do not create a new ResourceLocation instance every frame, use a static (final) field for it.

2. The z value (or correctly, the z-index) is the "layer" your texture draws on. It is recommended to use the field provided in your Gui instance.

[Enginecrafter]

I created new basic gui to test this and it worked, but on the advanced gui(the original gui) isn't still working. They are both using the same gui texture.

 

My function to render rectangle contained in texture on gui

[SanAndreaP]

... and where do you call your drawRect method (which is useless, since it's the exact copy of drawTexturedModalRect)?

 

A fundamental question: What do you want to achieve with your advanced GUI that is different from a basic one?

Also I suggest you setup a Github repo and host your mod code there so we can help you better.

[Enginecrafter]

The advanced gui is "advanced", because it uses lot of buttons, sends packets and so on.

I want ot create something like password lock that when correct password is entered, changes block on location that is set using my item "remote manipulator" and the block sets remote block's metadata to 1. Once the remote receiver has metadata 1 it emits redstone signal.

And, I don't want to create GitHub because I must update it every time I post something.

 

And there I call the function:

@Override
public void drawScreen(int x, int y , float tick)
{
	int[] screenPos = MainLib.createScreenBase(new int[]{width, height, 194, 168}, this, res);
	MainLib.drawRectangle(new int[]{screenPos[0], screenPos[1], 0, 177, 68, 20}, this.zLevel);
	super.drawScreen(x, y, tick);
}

Enginecrafter, the advantages of having your project in Git is that for instance you can develop your mod from everywhere where there is IDE and if your hard disk fails you will have not lost your project. I myself would be lost nowadays without Github repo.

[Enginecrafter]

Sorry, I have never worked with GitHub.

[Enginecrafter]

And, Have I to copy-paste all my code to GitHub?

Or there is a "simple way"?
