UNET - UI Not updating with Healthbar and other bars.

Questions & Answers
1

Hello,

So when I run the game, the Health and such will go down in the inspector, but it wont on the UI Healthbar, and the 2 other bars( thirst and food ). Is there an easy fix for this problem? Or does it involve a full remake of this script ( Singleplayer works fine, converting to Multiplayer).

All suggestions welcome, I’d happily try them out.

Thanks for reading.

Why don´t you use a slider?

slider.value = playerHealth;

I see your using images and I don´t understand why
