SetActive() – L’atelier d’Hyobin

UNITY | Project | RPG Tutorial | 21. Complete Quest

add gateTrigger to allow player to open the gate when he has received his this quest

when Player kills the boss, Update the Quest Manager to proceed to the next Quest

duplicate NPC001 and make it as NPC001_complete
- which has different saying
- activated when the boss is killed

create variables for
- enemy health as 20 for boss
- spider boss itself
- flag for spider’s status
- EXP when we kill the boss
- EXP calculated relatively to Player’s level
- spider’s AI
- spider’s status
- NPCs
- flag for spider’s attack
in Start() method,
- get the components of SpiderAI and SpiderAttack
create a function, DetuctPoint(),
- when enemy is attacked, enemy’s health is decreased by the damageAmount
in Update() method,
- make the spider’s status as global
- if enemy’s health is less than 0
  - start the coroutine, DeathSpider
create IEnumerator DeathSpider(),
- when spider is dead, disable the AI Script
- set the spider’s status as 6
- calculate the EXP
- play the animation for death
- turn on or off the NPCs

create variables
- distance between Player and Gate
- UI Buttons
- Gates themselves
in Update() method,
- get the distance by using PlyerCasting Class
in OnMouseOver() method,
- if the distance is less than 3
  - Player’s attack is blocked
  - showing the UI Buttons
  - if Action Button is pressed,
    - the collider attached to the gate is disabled
    - update Attack Blocking
    - UI Buttons disappear
    - play the Animations of opening Gate

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

FadeIn is located on Canvas, where UI button is
with FadeIn on, the Buttons are under FadeIn (since FadeIn’s opacity is 0, we can’t see them)
the Buttons can’t be touched

even though we set the second UI Text shrinks automatically as soon as we open the chest, before shrinking the second UI Text was not activated.
- there was nothing to shrink

in Update() method, the local scale of UI-Text will be turned off when the localScale.y is less than 0
- however, localScale is only set in Update() method.
- there is no chance to access the localScale’s premier value
  - in Start() method,
    - set the localScale of UI-Text for Unity to access the value

add SpiderAI as a component in the script
make spiderStatus variable as global by using static variable
spiderStatus = 0, means the spider is dead
- when spider is dead, disable spiderAI script attached to Spider

setActive() vs enabled

setActive() turns off the gameObject

enabled turns off a component in the gameObject

create an int variable as an indicator for spider’s attacking
with another indicator, attackTrigger 1,
- spider stops and the attack animation is player
- IEnumerator TakingDamage() is played
create IEnumerator TakingDamage()
- when an attack is done, set the indicator, dealDamage is set to 2
- unless spider is dead,
  - Player’s health is taken by 1
- wait for 0.5 sec

make this script reasonalbe
- when Player has only one heart, turn off the second and third ones
- when Player has two hearts, turn off the third one

in Build Setting
- add the first scene and the game over scene
- pay attention to the scene numbers

in Update() method,
- put the Raycasting to get the distance from NPC to Player
in OnMouseOver() method,
- if the distance between NPC and Player,
  - set the status of Player’s Sword into 1, unable to attack
  - show the message through UI Text
  - if Action Button is pressed,
    - set the status of Player’s Sword into 2, unable to attack
    - show Mouse Cursor
    - turn off the first UI Texts
    - get the Coroutine started
in IEnumerator NPC001Active()
- show Text UIs for NPC talking
- wait for 5 sec
- turn off the UIs for NPC talking
- show the first UI Texts
in OnMouseExit(),
- set the status of Player’s Sword into 0, able to attack
- turn off the first UI texts
