Creating Animation for Sword

Creating Animation for Sword

Creating Animation for Sword

• create an Animation
  • by changing Transform(Position & Rotation) however I want
  • for each frame we can add changes

Creating Animation for Sword

 

“Animation” Component

• Remove Animator(New)
• Add Animation(Legacy)
  • Put the Animation for Sword in Animation Component as Animation & Element0
  • Since we have one animation, Set Size into 1

“Animation” | Legacy

• in Animation Component,
  • in Debug tap, check Legacy

Animation | Wrap Mode | Once

• to make Animation play once, change Wrap Mode into Once

InputManager | Key “Fire1” for Left Mouse Button

“SwingSword” Script

• create Variables
  • for Sword we are yielding
  • for the status of sword

Animation Working

Adding Script to Sword

“AttackBlocker” Script

• create a script to prevent Player from Yielding Sword in specific conditions
• create variables one static and the other as path
• in Update() method
  • put the static variable in the path variable

Adding “AttackBlocker” into “GlobalStat”

“Quest001” Script

• add AttackBlocker.blockSword to Quest001 to change the status of swinging Sword
  • in OnMouseExit() method,
    • set the status as 0, indicating Swinging is available
  • in OnMouseOver() method,
    • when Action Button is pressed,
      • set the status as 2(actually 1), indicating Swinging is not available when grabbing the Notice
    • when Distance is less than 3,
      • set the status as 2(actually 1), indicating Swinging is not available when standing in front of the Notice Board

“SwingSword” Script

• Add AttackBlocker.blockSword ==0 to the condition of if statement

Swinging Sword is not working

 

UNITY | PROJECT | 2D PlatFormer | 3. Basic Enemy

“PlayerControl” Script

• Create a bool variable isGrounded as Flag
• Create OnCollisionEnter2D() method,
  • when a collision with an object tagged “Ground”
    • the flag is set to “true“

Tagging “Ground”

Collision Detection Working

“PlayerControl” Script

• in Update() method,
  • add code as a condition for Player to jump
  • when the button is pressed and at the same time the flag is true(Player is grounded)
• in Jump() method,
  • add code to set the flag to false

Box not tagged

Ground Tagged

 

Jump

• Player is not jumping on Box because Box is not tagged as Ground

 

 

Creating “Enemy”

• Create Enemy
  • add BoxCollider
  • add RigidBody2D
  • add EnemyControl Script

 

“EnemyControl” Script

• Create variables for Enemy‘s speed and direction
  • Enemy is moving horizontally only, so take care of X
• in Update() method
  • access velocity property to move the gameObject by using GetComponent

“Enemy” Inspector | Public Variables

 

“EnemyControl” Script

• in Update() method,
  • add RayCasting to perceive the obstacles
  • Physics2D.RaycastHit2D(vector2 origin, vector2 direction)
    • the origin where Ray is cast from is the current position of gameObject
    • the direction of casting the ray is only x
    • when the length of ray is less than 0.7,
      • activate Flip()
  • create a function, Flip(),
    • change the direction in x opposite whenever this function is called

“Enemy” Inspector

• put Enemy in Igonore Raycast layer
• set the speed

 

Enemy Moving

 

When layer is defualt

Input Manager

 

Player Jumping too high

 

RigidBody2D | Linear Drag | Gravity Scale
