C# Power-up spawn system (selecting and releasing), need help scripting

Questions & Answers

Hello guys, I’m a beginner unity user and want to script a power-up spawn system for the power-ups I made.

The power-ups are inside a canister, that when the player triggers (by colliding to it) it will instantiate another object which have a power-up effect script - such as deleting enemies that hits it)

Anyway I want a way to spawn the powers in my game; so here my idea on how it will behave.

  • An ONGUI screen will come out with buttons that represent a power-up - SIMILAR TO THISalt text
  • If the player presses the button, it will enable the power-up to spawn in our spawner script
  • NEED HELP WITH The spawner script always have to check if the game has 4 power-ups, if not, in 5 seconds it will spawn a new RANDOM power-up from a list of power-ups that was unlocked (player enables them by clicking the button from the ONGUI)
  • The power-ups will shoot random (360) from a point (empty game object)
  • Then I will add a force to it, so it shoots out

I have the basic Idea on how to do this, but I don’t have the experience and knowledge to write the code by myself.

  • Basically we need to put my power-ups in an array of empty gameobjects, I have at least 13 power-ups that the game can spawn.
  • Then it has to check if that power-up is activated by a bool i guess,
  • If it is activated (unlocked by player), then the spawner will random select 4 of those unlocked power-up to spawn in the game… we could probably do this by having a script that checks if the power-up is unlocked and then have it add to another array of only unlocked power-ups,
  • Then out of those new array of unlocked power-ups, the game will spawn only 4 random power-ups, each time that the game has less than 4, it will wait 5 seconds before spawning a new one.

I think I have the basic Idea just need help with the layout of the script, if you have even a tutorial on how to do it then awesome :slight_smile:

Please help me guys

use

Array.RemoveAt()
Array.Add()
and 
Array.length

to manage the array of power-ups.

you can have the script that detects collision find the spawn object and call a method to remove it from the array.
