This was originally built with laser ignition but upon figuring out how hard it is to spawn just 1 geom with lasers, I resorted to good-ol' Phun-style onCollide:tup:

I am not actually sure how much horsepower this thing has, cause I didn't bother doing a calculation to figure it out. It isn't likely to be very high though, because the stroke is so short.

Hear ye! Hear ye! Updates...
-Hinges actually suspend it now. It was previously just glued to the background.
-The particles now spawn **inside** the engine. Which means it will still work if it is moving. :)

And sure, you can use this in your own projects. However, until I am able to increase it's power I am afraid it will probably be quite useless. Just be sure to give me credit as the creator:)

Awesome :tup:
If you want the spawned circles to be back, add to the sapwn script

zDepth := the object you want the circle to be upon's zDepth + 1

You'll find zDepth as the last item in the script menu

Yeah, I knew that. But what I meant was the particles will spawn outside the engine if it is moving.

Sorry about wording that badly, I fall asleep in grammar class all the time...

Oh, yeah you have to spawn with pos := pos or e.other.pos, and with vel := entity.vel. If you use pos := e.pos the balls are spawned in the position of the collision but from 1 step ago

Old tricks? I was using lasers for few of my scenes but i seen how unstable my RPM's was.
So we have here 1050 max of torque witch is not bad...
And 820 on 477 RPM's so it has 54.9 HP if my calculations are right...
Nice one!

Oh... god. 54 hp. From a 200 kg engine.

I think it could use a little tuning... :)

For example... the density of the spawned geoms on full throttle is only 100, I think that could be increased.

Also, I did use laser ignition on my Lancia. It actually didn't work too bad, but the engine became very unstable at high revs.

I use up to 520 KG/M2 for high end engines, that is like my max for street cars and light trucks, but for the heavy ones it can be up to 1500 depends on how much power it needs and how much engine can handle.

I found it had a tendency to explode if it were raised above about 400. I think 250-ish is a better number however, it will run very stable at that point; I'll update it tomorrow, my mom's yelling at me to go to bed. it's about 11:00 in the states right now...

The problem of putting more than 400 kg/m2 density on a long stroke engine is that it produces... side effects, like flying :lol: so try not to put more than 200. And add gun tech so you can get more torque, normally you'd get like 2000 or 2500

Also why the weird timeToLive timing? say that the pistons' collision layer are A for the front and B for the back, add A+C to one ball and B+D to the other, and put a killer with collision layer C+D. also you can put the guns' collision layer as C+D in that case.

Yeah... this is kind of a bad design, I will admit. The stroke is far too short, those kinds of things are better for engines that get most power through rpm.

I haven't had any issues with using timetolive as a timing method. I think it actually works quite nicely.
