UI – L’atelier d’Hyobin

UNITY | PROJECT | RPG Tutorial |5. RayCasting

creating a static variable for the distance of RayCasting
- create another variable as a internal path for the static variable
in Update() method,
- imply a RayCasting from the mission board, with the direction of forward
- with out keyword, put the information of RayCasting into hit variable
- put the distance between the mission board and player in toTarget
- connect the static variable and the path variable

creating Variables
in Update() method,
- put the distance from the RayCasting in PlayerCasting Class into “distance”
  - for this, distanceFromTarget is set as Static
in OnMouseOver() method,
- if the distance of RayCasting is less than 3,
  - set ActionButton and ActionText active
  - if Action button is pressed,
    - set actionButton, ActionText, and Player inactive
    - set UIQuest and Notice Camera active
in OnMouseExit() method,
- set actionButton and actionText inactive

Be careful with the position of Triggers
If it’s buried in the other objects like the notice board, it is not detected by RayCasting

add UI – RawImage
- The Raw Image control displays a non-interactive image to the user
- Since the Raw Image does not require a sprite texture, you can use it to display any texture available to the Unity player

Since ViewHearts are Child Object of Heart, their position is based on the Heart’s

Create Variables
- to use in another script make heartValue as Static
- internalHeart is to be used as a path to heartValue
- to use Heart, Create GameObject as a vessel
in Update() method,
- create if statement, making Heart Active, whenever Player collects one

“when Unity says, “There are 2 audio lister”, remove main camera if you are using FPS Character”

In UI Button
- Set the size
- Add Sprites for “Target Graphic”(usual) & “Pressed Sprite”(pressed)

create “GameManager” GameObject as a reference
set “Player” inactive for the first moment of Game
In “Init()” method, which is called when Game Starts
- set the current life(“lives”) as MaxLife
- update UIText by using Text.text property
- change the number(int “lives”) to string by using int.Tostring() method
- set Player active when Game starts
In “OnTriggerEnter2D()” method(when a Collision with Player happens,)
- the life is subtracted
- when the life is 0,
  - use “SetManagerState” in “GameManager” Class with “GameOver”()*(putting the name of “enum”)
  - hide Player GameObject by set it “false”

In Play Button,
- Add Sprite for “Target Graphics”(Usual) and “Pressed Sprite”(Pressed)
- Add “On Click()” event and designate it “StartGamePlay()” method in “GameManager” Class
- with this part, No Need to write to Star Game

Add “GameOver” Sprite
- add the sprite to GameManager
- add the Sprite to the scene

Create a Function, “UnscheduleEnemySpawner()”, to stop the spawning when the game is over” by using “CancelInvoke()”

Create “ChangeToOpeningState()” method
- use “SetGameMangerState()” method
In Case of “GameOver”,
- put “UnscheludeEnemySpawner()” method to stop the spanwing
In Case of “Opening”
- turn off “GameOver” by using “GameObject.Setactive()”
