[SOLVED]Get the width/height of an image loaded from a resourcelocation.

[ItsAMysteriousYT]

I implemet a custom path with the IResourceLocation and add it to the defaultresourcepacklist. Now i wanna get the width and height of the images in that folder. How can i do this?

[Failender]

Im not sure if this is the best way, but the ResourceLocation also gives u the absolute/relative path for JavaIO. so u can go ahead, load the image inside an buffered image (goolge is your friend) and call the methods for getting width and height there. but java io is expensive so dont do this a lot.

[ItsAMysteriousYT]

Hm, is there a better way then?

[ItsAMysteriousYT]

Okay, so is everything alright in this file? Because i do not have an assets folder in that folder.

why are you building the path urself? ResourceLocation.getResourcePath should give u the path u need to create a new File

Ah - okay. Anything else?

[ItsAMysteriousYT]

Is this alright?

@Override
public InputStream getInputStream(ResourceLocation p_110590_1_) throws IOException {
	return new FileInputStream(RealLifeMod.MinecraftDirectory+"/images/"+p_110590_1_.getResourcePath());
}

[Failender]

how about u find it out urself? Learn how to use sysos for debugging please.

[ItsAMysteriousYT]

With sysos u mean System.out.println() and system.err etc?

[Failender]

yes.

[ItsAMysteriousYT]

Okay - i got it workin Thanks though!
