About This Game

• This game is focused on physics based off road truck and bus simulation. The main priority is tire deformation and suspension simulation for heavy vehicles.
• At this stage the game contains 25 vehicles and 5 maps.
• At the moment there are transport missions in the game, you can deliver cargo, you can earn money which can be used to buy vehicles and fuel.
• The approach taken to simulating vehicles was to start with simulating a tire using soft body physics in order to be able to deform similarly to how a real life tire would.

• The tire is attached to a solid rim which is attached to a soild axle which is attached to the suspension (leaf springs) and the suspension is attached to the frame.
• On the frame there are other parts attached, truck cabin, drive shafts, dump box, hydraulic cilinder that lifts the dump box and mud flaps.
• The tires, the suspension, the frame use soft body physics and the rest of the parts rigid body physics.
• All the parts have their own mass, they interact with eachother and this is what determines the vehicle behavior.
