◆ QPhysicsMaterial()

QT_BEGIN_NAMESPACE QPhysicsMaterial::QPhysicsMaterial ( QObject * parent = nullptr )

explicit

\qmltype PhysicsMaterial \inqmlmodule QtQuick3D.Physics

Since: 6.4

Defines the physics material of a body.

The PhysicsMaterial type determines how objects interact when they touch.

Friction uses the Coulomb friction model, which is based around the concepts of 2 coefficients: the static friction coefficient and the dynamic friction coefficient (sometimes called kinetic friction). Friction resists relative lateral motion of two solid surfaces in contact. These two coefficients define a relationship between the normal force exerted by each surface on the other and the amount of friction force that is applied to resist lateral motion. While most real-world materials have friction coefficients between {0} and {1}, values above {1} are not uncommon. The properties accept any real number greater or equal to {0}.

Restitution determines how objects bounce when they collide.

\qmlproperty float PhysicsMaterial::staticFriction This property defines the amount of friction that is applied between surfaces that are not moving lateral to each-other.

Default value: 0.5

Range: {[0, inf]}

\qmlproperty float PhysicsMaterial::dynamicFriction This property defines the amount of friction applied between surfaces that are moving relative to each-other.

Default value: 0.5

Range: {[0, inf]}

\qmlproperty float PhysicsMaterial::restitution This property defines the coefficient of restitution, or how bouncy the material is. The coefficient of restitution of two colliding objects is a fractional value representing the ratio of speeds after and before an impact, taken along the line of impact. A coefficient of restitution of 1 is said to collide elastically, while a coefficient of restitution < 1 is said to be inelastic.

Default value: 0.5

Range: {[0, 1]}
