Unity 3d implements just physical strength

1. Select the object that has the rigid body added, and then add the constant force assembly.

This component can add a constant force or torque force to a rigid body, often used in a single-shot rigid body, such as a simulated rocket launch. The initial speed of this object is not very large, but with the passage of time, the acceleration will be more and more large.

Force: Add forces directly.

Relative force: Add relative forces.

Torque: Add torque force.

Relative Torque: Add relative torque force.

2. Sketch out the use of gravity option for the rigid body, then set the y-axis force to 0.5, when the game is running, the object will still fall.

We can use code to add force to a rigid body.

void Fixedupdate () {if (Input.getmousebuttondown (0)) {rigidbody. Addforce (0,10,0);}}

Add the script to the object. And then run

When clicked, you will see the rigid body rise slowly.
