Fixed render crash when placing Universal Cables on ValkyrienSkies ships

[Andy608]

Changes proposed in this pull request:

• Added ValkyrienSkies and Eureka as runtime mods to help with mod compatibility testing. (KotlinForForge as well since VS relies on it)
• Updated the render function in RenderUniversalCable.java to check against null refs. Previously, getTransmitterNetwork() would return null when initially placing or removing a cable from a VS ship which would cause the client to crash.

Now with this fix, the client no longer crashes and players are able to place cables on VS ships.

This fix is in response to the open issue on the ValkyrienSkies github page: ValkyrienSkies/Valkyrien-Skies-2#558

Valkyrien Skies should be checking net.minecraft.client.renderer.blockentity.BlockEntityRenderer#shouldRender which runs through mekanism.client.render.transmitter.RenderUniversalCable#shouldRenderTransmitter and would not return true if there's no network.

Sounds good, thank you! I have been trying to get ValkyrienSkies to compile with Mekanism as a runtime mod in their repo, but I continue to get this error when running the game:

Caused by: java.lang.NoSuchMethodError: 'java.lang.String net.minecraft.Util.m_137492_(java.lang.String, net.minecraft.resources.ResourceLocation)'

Has anyone run into this error before? I would love to investigate this issue from the VS side of things, but I can't seem to get it to compile properly. I had no issues getting ValkyrienSkies running in mekanism's build.gradle, so I'm not quite sure what I'm missing. Any help is appreciated. Thanks!

Okay figured it out, and have submitted a fix on the VS side here: ValkyrienSkies/Valkyrien-Skies-2#1006

[Andy608]

After further investigation, it turns out the VS side change isn’t the ideal fix. Using shouldRender() causes beds and other uniquely shaped objects to become invisible. I believe adding a proper null check here would be sufficient in this case, though I’m definitely open to other suggestions if anyone has ideas for a better solution.

I also see render() calls shouldRender() so I'm still uncertain how the cable's render is even getting called. I'll need to do some more investigating on this.

For now, I’m using a custom-built version of Mekanism with the null check locally to prevent crashes.

can it actually be reproduced with only Mekanism and VS?
They're right that it shouldn't be needed, but its either not being called or there's a race condition somewhere

[Andy608]

Yee it occurs with only VS and Mekanism installed together. I found that adding shouldRender() to MekanismTileEntityRenderer fixes the crash (see most recent commit)

[thiakil]

Can you send a crashlog with just Mek and VS?
