Game Programmer Interview Questions and Answers
Q1. How to make an update function from a coroutine
To make an update function from a coroutine, you can use a while loop with a yield statement to control the timing of updates.
Use a while loop in the coroutine to continuously run the update function.
Use a yield statement to control the timing of updates, such as WaitForSeconds for a delay.
Example: IEnumerator UpdateCoroutine() { while(true) { yield return new WaitForSeconds(1.0f); UpdateFunction(); }}
Q2. What is the use of Fixed Update
Fixed Update is a method in Unity used for physics calculations and updates at a fixed time interval.
Used for physics calculations and updates in Unity game development
Executed at a fixed time interval, not tied to frame rate
Ideal for physics-related operations like rigidbody movement
Helps maintain consistent physics behavior across different devices
Q3. What is time.deltatime
Time.deltaTime is a variable in Unity that represents the time in seconds it took to complete the last frame.
Time.deltaTime is used to make movement and animations frame rate independent.
It is often used in calculations involving movement, physics, and animations.
For example, multiplying a speed value by Time.deltaTime ensures consistent movement speed regardless of frame rate.
Q4. What is an Interface
An interface in programming is a set of methods that a class must implement. It defines the behavior of a class without specifying how it is implemented.
Interfaces allow for multiple inheritance in programming languages that do not support it.
Classes can implement multiple interfaces, allowing them to have different behaviors.
Interfaces are used to define contracts that classes must follow, ensuring consistency and flexibility in code design.
