Hey I’m currently working on a single player experience and cant quite figure out how to go about this!

I am trying to create a dialogue system that works in first person. I only see stuff on how to do it for third person.

Essentially i want the character to go through a part to activate it and have a dialogue box pop up on screen. then i want the options of talking to the Npc to pop up attached to the npc floating after (as shown below)

Here is a example of how i want it to look:

u could use surface guis for that option and u could use screenguis for the dialogue.

I was trying to do that a while ago but never was able to interact with them for some reason

ok, can you show me the script you were working on?

where did you parent the billboardGui? try parenting it to PlayerGui

#7

cause text buttons on billboardGui wont work if its not parented to the player gui.

#8

Oh ok i had them parented to the Npc primary part which was the humanoid root part

#9

I tried doing this and it basically did what i want inverted.

#10

sorry but iam not familiar on billboard guis but i guess just make the dialogue text on a seperate screen gui.

#11

and im pretty sure theres a property called adornee to set the guis main part i think it goes like:

BillboardGUI.Adornee = Npc.Torso

u could make it so that the billboard gui is positioned next to the npc easily using adornee i think

#12

yeah im still not able to get it working unfortunately
