UNITY | Project | RPG Tutorial | 18. MiniMap Debugging, NPC Walking, & Saving Gold

“Quest001” Script

• add a line of code to turn off MiniMap off when approaching enough

MiniMap Turned On

Updating ButtonManager

Adding NPC | Setting Default Animation

Measuring Vector3 with Cube

“NecromancerWalkAI” Script

• create variables for
  • x, z position
  • where NPC head
• in Start() method,
  • set X, Z values with Random.Range()
  • set the NPC’s transform.Position with a Vector3 with the X, and Z values
  • Start the Coroutine
• in Update() method
  • make NPC keep looking at Cube(Destination) by using LookAt()
  • make NPC walk towards Cube(Destination) by using MoveTowards()
• create IEnumerator RandomWalk()
  • wait for 5 seconds whenever creating changing the location of Cube(Destination) 
  • set X, Z values which we measured with Cube(Destination)
  • change the Cube(Destination)
  • get the Coroutine started in the Coroutine
    • automatically the Coroutine will be repeated

the logic is, make NPC  play “walk” animation, create a gameObject where NPC keep chasing, and make NPC walk towards it

UNITY | PROJECT | SPACE SHOOTER 2D | 4. Enemy Animation & Enemy Spawner

Creating Enemy Animation

• by selecting multiple Sprites and adding them in the scene, Create “EnemyAnimation”

 

Changing the name of EnemyAnimationController

 

“Enemy” GameObject

 

“Enemy” GameObject with Animation

 

Adding “EnemyControl” Script to “Enemy” GameObject

 

“EnemyControl” Script

• Set the speed of Enemy with a float variable “speed”
• in “Update()” method
  • change the position of “enemy” GameObject with “transform.position” every frame
  • for memory usage, destroy “enemy” when it goes out of the screen

 

“Enemy” Moving

 

“Enemy” Destroyed when outside of the screen

 

Creating “Enemy” Prefab

 

Creating “EnemySpawner” & Adding “EnemySpawner” Script

• Create Empty GameObject and change its name into “EnemySpawner”
• Create “EnemySpawner” Script and add it to “EnemySpawner”

 

“EnemySpawner” Script

• To use “Enemy Prefab” in the script as a component
  • add “Public GameObject” variable
  • Don’t forget to add the reference in the inspector
• Create a custom Function, SpawnEnemy()
  • Instantiate()
  • after instantiating, set the position of Enemy in a random position by using random range of “x” value
• To make it spawn in 5 seconds
  • in “Start()”, write “Invoke(string methodName, float time)”
  • set the “maxSpawnRateInSeconds” as 5 seconds

 

Enemy Spawning

 

Don’t forget to add the reference

 

“EnemySpawner” Script

• Create a function, “ScheduleNextEnemySpawn()” to spawn multiple times
  • by using, “Invoke()” and putting “ScheduleNextEnemySpawn()” inside “SpawnEnemy()”
    • without using “loop”, we can make enemy spawned continuously
• To increase the difficulty of the game, Create a function, “IncreaseSpawnRate()”
  • in “Start()”
    • by using “InvokeRepeating(sting methodName, float time, float repeatRate)”
      • every 30 mins, the Spawnrate will be increased(Spawning gets faster)
      • In “InvokeRepeating()”, “time” is 0 and “repeatRate” is 30, meaning every 30 secs, “IncreaseSpawnRate()” is invoked

 

Spawning Enemies

UNITY TUTORIAL | PROJECT | SPACE SHOOTER |11. Game Controller

adding “Game Controller”

 

adding “GameController” Script

 

Instantiating “Asteroid” as “hazard” | deciding the location and rotation of instantiation

 

using a temporary prefab to get Transform values

 

putting the values in a public variable as a medium

 

instantiating GameObject in random locations by using Random.Range()

 

Quaternion.identity, no rotating

 

Instantiating “hazard” 1

Instantiating “hazard” 2

Unity 2D – Moving Object in Random Direction

Random.Range | Mathf.Cos | Mathf.Sin

Random.Range

public static float Range(float min, float max);

• Returns a random float number between and min [inclusive] and max [inclusive] (Read Only).
• max is inclusive, so using Random.Range( 0.0f, 1.0f ) could return 1.0 as a value.
