Scene tag

Realscale 4-cylinder W spawn engine powered car, with a 7-speed gearbox with Forward and Reverse.
Using what was already a stronger engine than the 4Cyl boxer and following the density point made by The Linkage x2.
Controls in-scene.
Course rightward to traverse.

Cool, but you can make it even better:

Change your spawn scripts to have density:=50 and pos:=pos, and you'll get a ton more power. Density is what generates a ton of torque, you can actually use up to ~500 but it might start to try to fly like a rocket engine. and using pos:= e.pos will make balls spawn in the position of the previous step, so it'll bug out at decent speeds, that's why you should use pos := pos.

with that you might be able to make the engine generate some serious power, and make it actually realistically sized (right now it's like 3.5 meters long lol)
you can try my latest dyno if you want to test the power, but remember to set the dyno's top speed correctly (400 or 500 rpm?)

Also try setting the gears' restitution to 0, and you might want to make the transmission springs much stronger:

constant = 1e10
damping = +inf
forceDirectSolve = true (just change the false to true on the script menu)

these springs will be extremely strong but you'll need to have the lengths perfectly or you could have some trouble

other than that it's a 10, you have no idea how many peeps just ignored the feedback
@The Linkage
Cheers, man. This is all making an amazing difference; I'd be daft to pass it off.

Updated the scene to suit. Going to do a fair bit more playing around and come up with a smaller engine, and I see what you mean about the lengths needing to be perfect; spontaneous exploding of the drivetrain is pretty spectacular.
it's definitely much better. The 2nd cylinder still has the messed up density though so power delivery is still rather uneven, but that's easy to fix. also another thing you might want to modify is the pistons and cylinders, they should be boxes if possible, with restitution 0. polygons are much worse in collisions, so you'll see that the spawning pistons bug out all the time
@The Linkage
Aye, easy fix. Noticed the engine output wheels weren't set up properly, so fixed that too; this thing can take off in 7th gear now quite happily.

Been working on a 6cyl that fits into a 1m square, and pretty quickly found the need for solid rectangles with that. Currently looking at high-rev short stroke cylinders, but those are having their own challenges.
this was definitely not a link

I really love this, good job... keep up the good work!
Great job with this machine! :tup:
