How to make a Helicopter with Spinning Blades

Hi guys! Bluesteel789 here!

So maybe you've played PPP_Killer's Jump Rope level, saw that awesome helicopter at the end, and just wondered how he got those blades on top to look like they're spinning? Well I did. After a lot of trial and error I figured out a way to make that effect, or at least an effect that looks very similar.

First we need a helicopter. Either make one up yourself, or go onto google images and copy one. Here's mine:

First, get out a piece of holo. Make it invisible by setting it's brightness to 0%. Now on top of that, stick a long thin decoration that you are going to use as a rotor blade. I used the decoration stretch glitch to turn the 'straight pipe' decoration from lbp1 into a long flat blade. To do the deco stretch glitch, you must:

• Place a Timer/Counter and make it very small.
• Next, place your decoration on top of this.
• Now go into the timer settings and change the length.
• You should notice that the decoration stretches when you increase the width setting.
• You must keep the deco on the timer for it to stay stretched.

So place your timer/deco on the holo. Now copy that four times, and rotate the deco each time. Like so:

Now we have our rotor blades, the next step is to emit them in order, so that it gives a spinning effect. Create four emitters. The first should emit the first deco/holo block. The second emitter should emit the holo/deco block next in series. Make sure the emitters are set so they only emit 1 at a time, and the destroy effect should be dissapear. Make sure the lifetime is set to 0.1. The emitters should emit the holo/deco blocks just above the 'copter, where you'd expect the rotors to go.
Now, we need to make the emitters emit! Set up a flicker switch (a 'NOT' gate linked up to itself) and connect it to the 'toggle' input of a four-input selector, as in the picture below.

If you want you could copy this bit of logic and shift the cycle along two, so that there is two, opposite blades at once. This would give the effect that the 'copter has four blades on top.

Thanks for reading!!

wow, been looking for the name of the glitch, decoration stretch glitch why did i not search that!?! any ways thanks, also i haven't tried it yet but if you covered it up couldn't you just stick the timer/counter on the base of the spinning drill from the incredibles pack?

I'm sure you could, but I don't own the incredibles pack. But that does sound like it would work, and it would create a smooth rotation, unlike this method which 'animates' the rotation.

I used the drill with decos to make my helicopter, so yes, it will work. I always thought it worked pretty well, and handily, decos placed on the end of the drill (the flat part) stretch out pretty long so I was able to make passable blades with the longer piece of gekko armor and I think one of the wrought metal fence-type decos.

I didn't know about the timer deco stretch glitch at the time, or I could have made an even better looking prop. The drill bit is pretty bulky so I used the compression tool glitch to embed it inside the material I made my chopper from--otherwise it would have looked weird.
