UNITY TUTORIAL | PROJECT | SPACE SHOOTER |12. Spwan Waves

instantiating “hazard” inside “for loop” 

 

setting public variable “hazard count”

 

multiple “hazard”s are instantiated at the same time

 

 

using “WaitForSeconds()” to put a pause between every instantiation

creating “coroutine” to use “WaitForSeconds()”

setting “Game Controller” using “coroutine”

 

spawning “a” wave

 

adding “while loop” to make in

 

having multiple waves of hazard

 

clones of “explosion” animation resting in the game

using “Destroy()” with “lifeTime” variable to remove useless GameObjects

setting destroy timer by selecting multiple components

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

UNITY TUTORIAL | PROJECT | SPACE SHOOTER |8. Boundary

Creating “Cube” as Boundary with Collider

positioning and scaling “Boundary” along with BackGround

Adding a Script for “Boundary”

Deleting any components of Mesh from “Boundary”

Casts a ray, from point origin, in direction direction, of length maxDistance, against all colliders in the scene.

Casts a ray against all colliders in the scene and returns detailed information on what was hit.
