Vehicles

Overview

There are three types of vehicles in Exodus SDK: car, boat, and trolley.

Car

You can add the vehicle/physx vehicle object to the level from the Entity List.

To activate the vehicle, you will need to attach a player via attach, then transfer the input from the player to the vehicle via mount vehicle.

Properties


				Center Of Mass Offset	The offset of the centre of mass of the machine relative to its root. You can customize it to change the stability of the machine. The lower is the offset, the more stable is the vehicle, and the higher is the offset, the more unstable is the vehicle.
Engine				Max RPM	This is the maximum rotational speed of the engine expressed in revolutions (rotations) per minute.
				Max Torque	This is the maximum torque available from the engine. This is expressed in Newton metres. A starting value might be around 600.
		Air Inlet			Contact of this shape with water stops the car.
				Offset	The offset of the air inlet relative to the root.
				Radius	The radius of the air inlet shape.
		Curve Graph			Amount of points on the curve of the engine. By default, it is 8.
Digital Input Analog Input	Raise & Fall Rate	Move	Accelerate	Rise	The speed of following the parameter input to the maximum target. Time in seconds, for which values will equal the necessary value (Rise) or 0 (Fall).
			Accelerate	Fall
			Break	Rise
			Break	Fall
			Handbrake	Rise
			Handbrake	Fall
		Steer	Left	Rise	Time that the wheel is rotating for a hardcoded 60 degree angle. Steering turns are set separately. We typically tune the wheels and the steering wheel separately.
			Left	Fall
			Right	Rise
			Right	Fall
Transmission				Differential Type	Differential type.
Suspension System	Wheels	Left Forward Right Forward Left Back Right Back	Tire	Type	Surface type of tires, which depend on the adhesion force with the surface type under the wheel. (This is set at the end of g_materials.lua). By default, it is slicks.
			Tire	Damp	Tire Attenuation Parameter. This simulates wheel resistance. The closer this number approaches to 500, the sharper the acceleration will be reset when you release inputs.
			Dampfer		The simulation of backlight. Counted toward the surface normal.
				Spring Compression, m	Maximum amount of compression (lengthening) of the suspension spring, vertically.
				Spring Elongation, m	Maximum amount of lengthening of the suspension spring vertically.
				Spring Strength, kgs	Spring Strength
				Shock Absorber Strength, kgs	Shock absorber strength
Steering System				Max Steering Wheel Turn, degrees	Maximum steering angle.
				Velocity vs Steer Size	The size of the table for Velocity vs Steer.
			Velocity vs Steer	Velocity - Steer	Dependence of the maximum steering angle on the speed of the car.
				Steer	Steering object (which transmits to veh_steer & veh_steer_deg).
				Speedometer	Speedometer object (which transmits to veh_speed).

Boat

Properties

Control		Velocity forward max	The maximum speed achieved by the boat when moving forward.
		Time acceleration forward	Time during which the boat reaches maximum speed when moving forward.
		Velocity backward max	The maximum speed achieved by the boat when moving back.
		Time acceleration backward	Time during which the boat reaches maximum speed when moving back.
		Time stop neutral	The time for stopping (neutral).
		Time stop brake	The time for braking from maximum speed.
		Forsage max velocity	The speed during forsage.
	Turn	Max Speed (Degrees)	Angular velocity of rotation.
		Power	Moment applied to the boat for turning. The maximum possible speed for turning.
		Time To Max Speed (ms)	Time to maximum angular velocity. Time during which the maximum turning force (acceleration) will be achieved.
Model		Bone with bottom	The bone that contains the shape in charge of the interaction with water (the contact with shape includes a floatage).
		Guide axis	The axis along which the boat will move.
Stabilization		Power	The moment of force that aligns the boat.
Stabilization		Tilt threshold (Degrees)	Threshold at which the stabilization moment will be applied in full. Up to the threshold, it is only partially applied.

Trolley

The trolley uses hardly any physics. All of its movement is implemented by triggers for input and play motion blocks.
