Question-12. How do you handle timers in UnrealScript?
Answer-12: Use SetTimer() and define a timer function.
Question-13. What is the purpose of Simulated functions?
Answer-13: Allows the function to run on a client in networked games.
Question-14. What is the Replication block?
Answer-14: Defines variables and functions to sync between client and server.
Question-15. What is the Static keyword used for?
Answer-15: Declares a method that belongs to the class rather than an instance.
Question-16. How do you spawn actors in UnrealScript?
Answer-16: Use the Spawn() function. Example: Spawn(class'MyActor', Location, Rotation).
Question-17. How do you destroy an actor in UnrealScript?
Answer-17: Use Destroy() method. Example: MyActor.Destroy().
Question-18. What is the purpose of the None keyword?
Answer-18: Represents a null reference.
Question-19. How do you handle input events in UnrealScript?
Answer-19: Override functions like PlayerInput().
Question-20. What is a struct in UnrealScript?
Answer-20: A lightweight collection of related variables. Example: struct Vector { var float X, Y, Z; }.
Question-21. How do you define a constant in UnrealScript?
Answer-21: Use the const keyword. Example: const int MAX_HEALTH = 100;.
Question-22. What is the Outer property of an object?
Answer-22: Refers to the object that owns or contains the current object.
Question-23. How do you log messages in UnrealScript?
Answer-23: Use Log() or Debug(). Example: Log("Debug message");.
Question-24. What is the purpose of Dynamic Arrays?
Answer-24: Arrays that can grow or shrink in size at runtime. Declared with array.
Question-25. How do you check if an object is valid in UnrealScript?
Answer-25: Use IsValid() or check for None. Example: if (MyActor != None).
Question-26. What is the difference between local and global variables?
Answer-26: local variables exist only within the function, while global variables are accessible throughout the class.
Question-27. How do you bind a function to a key in UnrealScript?
Answer-27: Use the Bind() method in the player controller. Example: Bind("Fire", OnFire).
Question-28. What is the purpose of Client and Server keywords?
Answer-28: Client indicates code executed on the client; Server indicates code executed on the server.
Question-29. What are latent functions in UnrealScript?
Answer-29: Functions that can pause execution, typically using Sleep() or timers.
Question-30. How do you make an actor visible or invisible?
Answer-30: Use SetHidden(true/false) or bHidden.
Question-31. How do you create a custom HUD in UnrealScript?
Answer-31: Extend the HUD class and override its PostRender() function to draw custom elements.
Question-32. What is the role of the GameInfo class in UnrealScript?
Answer-32: Manages game rules, player spawning, and other high-level game logic.
Question-33. How do you handle collision in UnrealScript?
Answer-33: Use functions like Touch(), HitWall(), and TakeDamage().
Question-34. What is the purpose of the bAlwaysRelevant property?
Answer-34: Ensures the actor is always replicated to all clients.
Question-35. How do you work with textures in UnrealScript?
Answer-35: Use the Texture class and assign it to materials or HUD elements.
Question-36. What is the difference between DynamicLoadObject() and StaticLoadObject()?
Answer-36: DynamicLoadObject() loads objects dynamically at runtime, while StaticLoadObject() is for compile-time loading.
Question-37. How do you apply damage to an actor?
Answer-37: Use TakeDamage() or call ApplyDamage() on the target actor.
Question-38. What are Mutators in UnrealScript?
Answer-38: Special classes used to modify game behavior or rules dynamically.
Question-39. How do you iterate over all actors in a level?
Answer-39: Use the AllActors() iterator. Example: foreach AllActors(class'MyClass', MyActor) { }.
Question-40. What is the difference between Simulated and Reliable functions?
Answer-40: Simulated functions are executed on clients; Reliable ensures guaranteed execution in networking.
Question-41. How do you implement AI in UnrealScript?
Answer-41: Use the Controller class and its derived classes like Bot. Override functions like Tick() for behavior.
Question-42. How do you create particle effects in UnrealScript?
Answer-42: Spawn a ParticleSystemComponent and assign a particle effect asset.
Question-43. What is the purpose of the bNetDirty property?
Answer-43: Marks a replicated variable as requiring an update to the client.
Question-44. What is the difference between Tick() and PostBeginPlay()?
Answer-44: Tick() is called every frame; PostBeginPlay() is called when an actor is spawned.
Question-45. How do you access player input in UnrealScript?
Answer-45: Override PlayerInput() or use Input.KeyEvent for specific keys.
Question-46. What is the purpose of the Destroy() function?
Answer-46: Removes the actor from the level and cleans up resources.
Question-47. How do you handle replication for arrays?
Answer-47: Use replication blocks and implement custom replication logic for arrays.
Question-48. What are Dynamic Lights in UnrealScript?
Answer-48: Lights that can change properties at runtime, often used for special effects.
Question-49. How do you debug network-related issues in UnrealScript?
Answer-49: Use the Log() function, test in network emulation mode, and verify Replication blocks.
Question-50. How do you optimize performance in UnrealScript?
Answer-50: Use efficient replication, minimize Tick() usage, and avoid unnecessary actors.
