It's 5 inline!
Anyways, good job.

It isn't a ball spawn engine, it's a collision.
The balls change collideSet and collide with a box with that collision group.
Yo can make it acceleratable, changing the two balls that change collideSet position.

If you don't understand me, that's not your fault . Just reverse-engineer one of my engines, or Kilinich's.

Anyways, good!

Or you can select the laser's trigger, and press the two keys at the same time.

Thanks!

By the way, have you seen my vw Gol? It uses a gun engine, and it works perfectly! You should receive an award for that, Gent!

It's really fast!
But maybe you should use a stretched hinge transmission (like Kilinich's one) to improve the strenght.
For the wheels I will try with springs or sth like that.
By the way, have you got a saved-before-testing version of this? It's really hard for me to work without the grid!

Make the balls change density (when they are up, density = 1000 or more, and when they are down, density=2)

Ok.

Done, Christier!
Just look at my profile.

Not only CGears, you may improve the timing too. That's the main issue!

Not so strong...

Gent: just press A, it's the engine brake.

Good! Just the CVT is working very slightly, it should variate more (just my opinion).
Anyways 10/10

It works well, but maybe it would work better with CGears. Try to make a bit bigger the spawned circles, and with less delay.
Or just look at my Wankel:

p.s: I talk Spanish too .

OH, and with 0.2 radius circles i've got 18 rad/s.

No idea what happens. Try reloading?

I'd say "Made with only Three hinges."
0/10

Ningún problema. Después lo subo a mi cuenta.

Thanks! I'll try to test with those circles again, just to see what happens.
The stretched hinges are very easy, just put the hingeConstant to the lowest value you can, but not 0 (something like 0.0000000000000000000001).

Try to get down the spawner a bit, and to get down the killer two squares of the grid.

And make the pistons heavier (a lot) and try to make a transparent piston behind the polygon!

Para mí, es lo mismo. Yo no uso ningún traductor, primero porque traducen mal, y segundo porque no los necesito, ya que estudio inglés.
Si te resulta mas fácil escribir en inglés, no tengo ningún problema.

But you are cheating with the weak clutch

@Gent: Put the two objects that you will hinge together overlapped, put a hinge, then hold ALT and move the object at the same time, then put the hingeConstant= 0.00000000000000000000001, but with a random quantity of zeros. Then, put the hinge motor, or brake, or what you want.

@faytree: Thanks! This engine has some more features, like no restitution at spawn and many other things.

Ok! We are just speaking spanish because pipe01 is spanish and I'm argentinian .
Maybe try making the killer to kill the smoke too, or not generating it at all, because you'd have a lot of lag.

Use boxes for the cylinders! You will get less strenght with a collision engine with polygon pistons!

Wow!
Spawn engine huh!
But you can improve it a lot!
Make the spawned circles to be spawned at the center of the block and the circles diameter must be of the distance between the engine block.
The circles must weight 0.5 kg, with restitution 0 (important)!
Anyways, good Ford Ka!

Much better!

thrcasper:

I mean that the spawned circle must fit exactly on the cylinder block, and be spawned on the center.
Then you should adjust the killers.

Ok, my engine (Rotary4 v2) seems to have 13300 HP at 100 RPM, scaled down to have the same size as yours!

i know!

It's easier than a spring engine! Look at the circles, they have denity -0.1 when it's idling, and -0.75 when accelerating.
It just has a density below 0, and it won't work without air friction.
