UNITY TUTORIAL | PROJECT | SPACE SHOOTER |9. Creating Hazards

Adding Asteroid as Hazard

 

Adding “RigidBody” and “Capsule Collider”

 

adding a script to give Tumbling

setting tumbling speed with a public variable

RigidBody.AngularVelocity | Random.insideUnitSphere

tumbling Asteroid but with Angular Drag

setting Angular Drag to 0

Asteroid tumbling without Angular Drag

adding a script to make destruction

OntriggerEnter to detect any collision | Destroy()

• Destroy(other) – only removing the collider
• Destroy(other.gameObject) – removing only the gameObject with Collider “other”

Bug | something is triggering “Destroy()” function

Debug.Log (other.name)

Debugging 1 | finding the cause

Debugging 2 | finding the cause

Debugging 3 | Tagging “Boundary”

Debugging 4 | detecting any gameObject with a tag “Bounadry” | return

• Return ends the execution of a function and hands the control back the function that called it (maybe Unity itself)
•  Return ends OntriggerEnter Function and returns the control back to Unity’s Game Loop
• As a result, if the object’s tag is “Boundary”, we will never reach or execute “Destroy” function

Debugging 6 | Solved

Asteroid destroyed by Laser

GetComponent

• we can get other components that are attached to the same Game Object this script is attached to by calling “GetComponent” and we put that component into a variable

RigidBody2D.AddForce

• public void AddForce(Vector2 force, ForceMode2D mode = ForceMode2D.Force);
• ForceMode2D
  • ForceMode2D.Force – Add a force to the Rigidbody2D, using its mass.
  • ForceMode2D.Impulse – Add an instant force impulse to the rigidbody2D, using its mass.
