PS : i use UE4 4.6.1 -_- , i saw somthing called Draw text i don’t know what is it exactly .

Do not use 4.6.1. I hope it was a typo and you meant 4.16. Update. No, seriously, update.

Look into widgets, this is how you create User Interface elements:

it was 4.6.1 , i need to update -_-
Thanks , btw

Draw Text is used with the HUD class - it can be used to display messages and UI elements but it’s both limited and limiting.

Ok i’ve updated to 4.17.2 thanks
