After seeing that mod that puts a grid for worldedit, it made me think...
It would be really awesome if there were something that you could load a schematic to and it would put a grid version of it, so instead of having to constantly check minecraftstructureplanner you could just have an overlay in your world showing you where to place things.
Sigh.... if only this mod were created. This idea doesn't seem to be getting much attention as it has been suggested a couple times before over the past couple years. I do continue to hope and occasionally browse for this or something similar.
Ive been thinking on how this mod would work and came up with something like this:
First you load in the clientside schematic of your choice.
Then with access to a "wand" of your choice you could select the corner of the build with one click, then with another select the direction in which the schematic should go to give it multi-directional support.
Once done with the second click it would load a transparent (configurable percentage) version of the schematic to start building from.
After you had the entire build you would then turn off the overlay.
Perhaps you could change the plugin config from the esc menu or from a plugin specific menu something like the F7 menu for the Zombe Mods.
Anyways this is just some thoughts ive had for the functionality of the mod. If only I had the sufficient know how to code it
