Laputan Blueprints Cannons

Is there any news on whether LB will include 'true' guns like Rigidchips?

Currently >> Takeya "I will build in neither a combat nor online play. However, I will prepare the infrastructure that other people can build in. For instance, it is Lua API etc."

Other than Bwansy's letters to and from Takeya, we have no other information on that matter.
If you on the adventurous side interest your buddies into building in LB, but the only combat I can see is building two 'Objects' sepertely with seperate controls and having a ramfest... T-T

or jet-based guns.

maybe someone will be able to build a V-3 cannon like gun able to launch projectiles at supersonic speeds.

anyway, my laptop runs the basic car at 20FPS with the "bis" physics model(half as much computational power as the standard one), so i can't design much.

Wow, I completely missed that. Canons, but how do we reload them? Other than the obvious 'u' or 'r'.

moving parts!

i don't think its THAT hard to make a blowback system on LB, althought someone might be wanting to use a robotic arm to manipulate objects...

Other than the 'holy schnitzel stick, thats one insane canon object' I think it's worth a try. But man, I'm glad Takeya went with blueprints compared to .txt!

I've been playing around with creating projectile launchers in LB, but the best I've managed to come up with is the projectilelauncher.lbd file included in LB... Not the best, but I guess it's a start. Bwansy's got a pretty cool gun in LB though, Gun1c.lbd.

Perhaps we should have an LB build off?

i found out something: the thrust force jets do is only related to the mass of the parent object. this means you can get more acceleration by using lots of small jets at the same time attached to a heavy object. this rocket uses this concept.
