+Title: People Playground Modding - PhysicalProperties
+==================================================
+
+public class PhysicalProperties
+Inherits ScriptableObject
+[CreateAssetMenu(menuName = "PPG/Physical Properties")]
+This class describes the physical properties, aka material, of an object.
+Fields
+public PhysicsMaterial2D PhysicMaterial
+The Unity physics material.
+Unity documentation: https://docs.unity3d.com/Manual/class-PhysicsMaterial2D.html
+
+public bool Sharp
+[Space]
+Determines if the material is sharp anywhere. This has to be true in order for the other sharpness-related properties to be effective.
+
+public float SharpForceThresholdMultiplier
+The amount of force necessary to lodge this material into another.
+
+public float LodgeStrengthMultiplier
+The amount of force necessary to dislodge this material.
+
+public SharpAxis[] SharpAxes
+An array that describes all the points on this material that are supposed to be sharp.
+
+public float Softness
+[Space] [Range(0, 1)]
+How easily sharp objects stab this object. Ranged from 0 to 1.
+
+public float BulletSpeedAbsorptionPower
+Determines how much of the kinectic energy in bullets is absorbed by this material.
+
+public float Brittleness
+[Range(0, 1)]
+How easily bullets go through this material.
+
+public float Buoyancy
+How much this material floats on water.
+
+public float Flammability
+[Range(0, 1)]
+How easily this material starts burning.
+
+public float MagneticAttractionIntensity
+How much this material is attracted to magnets. Has to be more or equal than 0.
+
+public bool Conducting
+Whether this material conducts electricity.
+
+public float Burnrate
+[Range(0, 1)]
+How fast this material burns (burn progress per second). Ranged from 0 to 1. These values are usually very low.
+
+public float BurningTemperatureThreshold
+The temperature at which the material starts burning.
+
+public float HeatTransferSpeedMultiplier
+[Range(0, 1)]
+Determines how fast heat transfers from this material to other materials.
+
+public AudioClip[] SizzleSounds
+The sounds this material makes when it is touched by a hot object. Can be null.
+
+public AudioClip[] SoftImpact
+[Space]
+The sounds this material makes when it collides softly.
+
+public AudioClip[] HardImpact
+The sounds this material makes when it collides with a lot of force.
+
+public float ImpactIntensityMutliplier
+This member has a spelling error. It determines how much harder the material considers the force of an impact.
+
+public float HitVolumeMultiplier
+Determines how loud impact sounds are. 1 means 100% as loud, which is the default value.
+
+public AudioClip SlidingLoop
+[Space]
+The sound this material makes when it slides or rolls.
+
+public AudioClip[] StabSound
+[Space]
+The sound this material makes when it gets stabbed. Can be null.
+
+public GameObject ShotImpact
+[Space]
+The prefab this material instantiates when it is shot. Can be null.
+
+public bool IsPoolable
+Is the shot impact effect a poolable object?
+
+public bool SparksOnSlide
+Should this material create sparks on slide?
+
+public bool IgnoreStabResistance
+[Space]
+Should this material ignore other material's stab resistance?
