Here’s my first experiments with tanks. Since wheels were overhauled I figured I’d try again to build something on land that wouldn’t simply careen into a dune and explode, which is what pre-2.0 vehicles did frequently. Now wheels actually have spring, so a row stays connected to the ground.
This is my first attempt, using front wheels to provide turning power. The chassis is too low to the ground and on rougher terrain would probably get stuck. Also this is the equivalent of braking to turn, so movement is awkward.
Here’s a second attempt, using turn blocks to make a pivoting axle. At first, something is wrong and the vehicle wants to spin in place. No bueno.
Turns out building the wheels upside down (in the spin block subvehicle) makes the ones on the left face reverse, so I just reverse the controls on them. Notice the arrow-shaped treads on the left vs right. Nice visual cue that didn’t used to be there.
Here’s a more compact version. However, even though I’ve got a great thrust-mass ratio, my top speed isn’t breaking 35km/hr. I figure this is a limitation of the new physics package (so that ground vehicles don’t become death sleds). I’m also going to need a much wider chassis and a suspension with wheels on both sides because this guy probably doesn’t have the torque needed to get up and down hills.
Here’s the next iteration, with what amounts to tracks. This is going to be needed if I’m going to mount an actual tank on top. Now it’s time to go off-roading.
Notice how the wheels are elevating to meet the ground - before 2.0, you’d get a fraction of your drive because half of your wheels wouldn’t touch ground. Even on a 45 degree incline, I’m still getting about 70% of max speed, not rolling over and not getting collision damage from the bumps.
Here’s my first (much too large and heavy) tank chassis. Recall the ultraheavy “Ferdinand” tank which barely participated in the Battle of Kursk and you’ve got a fair picture of what happened the second I drove this fucker off a hill. Spoiler: The suspension hit the ground with such force that it destroyed the entire axle. I could solve this equation with more suspension or a smaller tank. Since I don’t fully understand the minutiae of this new physics system, I’m just going to hack away some mass.
Couple improvements here: The suspension is built with rubber blocks, which take no collision damage. To compensate for the lack of durability, I added an armor skirt, but this had a habit of grinding off on terrain, so I replaced it with rubber, which at least keeps the vehicle from flipping.
Here’s the finished product. While not nearly as pretty as I’d like, and the wheels tend to fall off if you cough on them, it takes direct hits like a champ and the cannon is more than adequate. Everything is so compact compared to a surface ship (the ammo is literally located on the sides of the undercarriage because I ran out of room up top). Land combat is also wayyy different because you can quickly forward/reverse/turn so as to evade a lot of incoming fire, which you can’t really do with ships, so the relative lack of armor matters a lot less.
