How to keep TEXT information when reloading a level?

shorex1991 · Dec 25, 2017

Hi! first of all, i am newbie with this... i would like to know how can i keep an text showing up, after i picked up an item, on the screen even when i reset the level of the game - it's a rogue like game.

i did everything i could, but my knowledge is almost 0 here...

the game is almost complete, just need to set this (make the text allways show up) to finish.

the text "win( ,1,2,3,4,5,6)Text" which i want to make appear, will pop up after the score from the "count" triggers it, and will be active always after the levels resets

this is the code im using:

Code (CSharp):

You can solve this in two ways;
1: Save your text strings using the PlayerPrefs object, and reload them when you restart your level (load's the scene)
2: Make your GameManager a Singleton, and call DontDestroyOnLoad(GameObject) in the initialization of your object.

See this tutorial about saving and loading your high score, it might give you what you need:

Good luck with you game

You should search the internet a little bit for PlayerPrefs example and/or DontDestroyOnLoad.

PlayerPrefs is a dictionary of key value pairs, where you can save/load information. As said above, you could save your data, and when the scene changes, you load the data and display it , again.

With DontDestroyOnLoad, that tells the Unity engine to keep your game object between scenes. It won't be destroyed automatically, so if you have some data (manager) or even UI object, you can keep it between scenes. You have to choose what seems best for you. The best way to know what fits for you is to learn about them a little bit

Hope that helps.
