So my previous statement about the Duke Nukem mod update coming in July is, as you can see didn't come true. I decided to learn coding and THEN I'll come up with a better update.
Seems like the creator of the plugin that allowed me to do the destruction for the mini nuke round and the nuke without making your game freeze for some time has abandoned his project, which means there is no update coming for it.
The point of the plugin, which is called "Procedures Plus" (for MCreator) was that it let me generate spheres with easy and without lag. But now I'm left with the "lagging machine" method. In other words mulitplying the explosion of a TNT. Currently I don't know what to do. I will try to trial-and-error to find a way but currently I don't know what the fuck should I do.
Also this is the only major thing that is left. After that the mod is pretty much ready to be served.
