Wow, dang I need to remember that
I tend to make my builds pure trans yellow
Also...if you can get a scale change brick in there, its a good idea to make a "Vent system" for easy access around the base. This works if you make ultra thick walls with a mini'd passageway in there.
also, while this is not placing bricks, I should discuss bot placement with Rky's ad-bot mod coming out very soon.
Sentry: It seems as though they don't target in a cone (yet), so dont try to make tower snipers. Make ground floor window snipers instead. This setting would also go well in patrol bots in your hallways, just make sure you yourself can get around them, as they cant choose between ally and enemy (yet)
Attack bots: Don't make them go after an enemy thats is easy to get to (like inside of a room with the entrance on the other side)
Fire: Try to hold this off unless their holding off enemys comming out from around a corner. Fast fire weapons, of course.
Follow: just use the bot fetch command instead
Respawning: Remember that bots respawn facing north
Wander + sentry: Try to keep from doing this, because they'll shoot you as fast as they'll shoot your enemies. however this can still be effective, granted they dont get stuck in an odd corner. Reserve wander for later until you ideot-proof your build.
My bot got stuck!: Theres a fetch command in the GUI
I know this isnt brick placing, but still, its useful should bots be allowed in your fort.
