Unity3d Small opposed common scripting API (transform, time, Random)

The Unity engine provides a rich set of components and class libraries, so I'll give you a brief introduction to the transform, time, and Random that I use more often.

One, transform components

The transform component determines the position, orientation, and scale of the game object, which is used to set the camera's viewing angle and update the player's position.

member variables and member functions are not listed first, there are in the Holy Scriptures.

Simply say the application:

1, around its own axis y rotation

float speed = 30.0f;

Transform. Rotate (Vectoe3.up*time.deltatime*speed);

2. Move forward

float speed = 30.0f;

Transform. Translate (Vector3.forward*time.deltatime*speed);

3, around the world axis y rotation

float speed = 30.0f;

Transform. Rotatearound (Vector3.zero, Vector3.up, speed*time.deltatime);

Second, time

Time-related.

1, the game from the beginning to now experience the time

2, Deltatime time spent on a frame

Third, Random

Generate random numbers, rotations, random things.

Rotation: Random rotation

Random floating-point number from value:0 to 1, including 01
