[1.12.2] TRSRTransformation question [SOLVED]

Recommended Posts

Myproblem: weird rotation when using TRSRTransformation while baking IModels caused by the rotation axis not being in the center of the block.

Solution: Use TRSRTransformation.blockCenterToCorner to convert your TRSRTransformation (even though you would intuitively use TRSRTransformation.blockCornerToCenter).

 

Original post:

Spoiler

I tend to use TRSRTransformation quite a lot as I often do manual model baking. I noticed when constructing a new TRSRTransformation , my rotation around y-axis doesn't happen around the center of the block, but rather on one of its corners. And also mixing translating and rotating together doesn't happen as I expected it to happen.

 

So how do I combine

1) translating (let's say 0.5 blocks north) and then

2) rotating by 90 degres around y-axis (with the axis going through the center of the block)

Translate (-0.5,-0.5,-0.5)

Rotate

Translate (0.5,0.5,0.5)

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Well this doesn't work:

 

TRSRTransformation.blockCornerToCenter(new TRSRTransformation(
					closed ? null : vector, 
					null,
					null,
					TRSRTransformation.quatFromXYZ(0, (float) Math.toRadians(90 * direction.ID), 0)));

 

It gets properly rotated, but again it also gets translated weirdly

    • and what is called OreFeatureConfig, while making ore gen
    • I have been trying to download Forge but the Windows Installer isn't coming up, I can see the installer one would use for Linux but no Windows, I have downloaded Java and Jarfix but nothing is working, can someone help?  
    • So I thought that when a capability is attached to an item/entity/etc... the capability will stay until whatever it's attached to is gone. But this doesn't seem to be the case, as when I printed to console whenever a capability is attached, it seems as though a new version of the capability is attached to an item every time I select it in my hotbar, hover over it in inventory, etc. Is this how it's supposed to work? If so, why?
    • Hi, I'm trying to set up a simple forge server just to play with a couple of my friends, but no matter what I do or try I cannot seem to get a Mods folder and for the actual forge part of the server to actually launch. Every time I try to launch the forge.jar via a .bat file I just get a bunch of errors [Errors below] I'm not sure what I'm doing wrong. If I can get some help that would be awesome, thanks C:\Users\User\Desktop\Server>java -Xms2G -Xmx6G -jar forge-1.12.2-14.23.5.2855.jar nogui A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException         at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)         at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:78)         at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)         at java.base/java.lang.reflect.Method.invoke(Method.java:567)         at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:70)         at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:34) Caused by: java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')         at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34)         at net.minecraft.launchwrapper.Launch.main(Launch.java:28)         ... 6 more C:\Users\User\Desktop\Server>pause Press any key to continue . . .
