Draw a line with emitters..?

Archive: 7 posts


There is a team pick level called SURGE lite (i think) that has the effect I'm trying to achieve. How did he do this?

I'm trying to draw a line by attaching an emitter to a peice of material set to follow touch. The emitter is just emitting little peices of sticker panel which I hope will form a line when you drag your finger across the screen. But the emitter won't emit fast enough so I end up with a dotted line. I've been tooling around with this for a week now and can't seem to get what I'm trying to achieve.

Any ideas on how this was done

There's a tutorial here on the forum that shows you how to do it: https://lbpcentral.lbp-hub.com/index.php?t=74478-Nice-bridge-with-one-emitter2013-09-18 09:41:00

Hey Sweet.

I have a locked WIP level (http://vita.lbp.me/v/db5qg) sitting around on my Earth. I'll make it copyable in my lunch break, and you should be able to rip the drawing logic out of that one.

The best trick I have found is to scale the emitter speed with the movement of you finger - faster movement = faster emit. There is a theoretical limit of 30 new emitted objects pieces ? second (one each frame), so should you move you finger "really" fast, you will always see a dotted line...

I hope this will help you

Slaeden-Bob, you are going to regret giving me your logic buddy!! Now my draw level is going to be eons better than yours! NaaNaaNuhPooPoo!

Haha, just kidding. I have copied it to my moon. So you can lock that bad boy back up if you want. I'm looking at it now and I have no idea whats going on. LOL. I'll pick it apart more later and see what I can deduct from it.

Anyway big thanks, and now I don't have to worry about the max emit of 100. Sweetness!


PS.. I looked at the SURGE Lite level again by Evret, and as silly as it sounds.. his line looks as though it's made up of circut board wires? How is that possible?

Hehehe. No that doesn't sound silly at all

Evret is a very clever and inventive creator! I checked out the level, and it really seem like he used circuit-wire to draw with...

I'll see if I can lure the secret out of him

U can emit solid objects inside each other naturally. Just haver the anti grav option on the object turned on. maybe this is how evret did it?

But yeah I have noticed a difference in emitting speed between LBPv and lbp2.

Yeah I wish I understood what was going on speed wise. I tried to make emitters fire faster than they do but couldn't pull that off. lol.

I supposed Evret is using tools we don't have access to...
