If i have in my mod this:

 

assets\minecraft\textures\gui\container\crafting_table.png

assets\minecraft\textures\gui\container\inventory.png

 

should this not replace the minecraft textures?

It doesn'r replace it at all and no errors.

I thought a mod functions also as a resource pack

That should work, it does for my test mod:

 

Weird! Why doesn't it for me?

here a picture:

I just deleted everything and then created it all new and it works now.

I have created the folders now in the explorer and not in eclipse, maybe that causes this.

It is because of this:

 

You actually have called the folder

minecraft.textures.gui

. This is 1 folder and not 3 folders underneath each other. If you make the folders separately, like your other folders, it will work fine from Eclipse.

I don't think this is completely true.

The dot between separates it. If i go look with the explorer those folders are there.

Eclipse keeps it together like this because those folders are empty.

As soon as you put 1 file or a subfolder in it it will split.

 

I created the folders now by hand in the explorer but it still looks the same as before in eclipse, yet it works now.
