Dialogue System

Unity Engine
1

Let me briefly point out what i’m working on…
1.it’s a dialog system that would run in background without the player interaction.
2.player can view the dialog when he interacts with the NPC having this script

But when i add the script on multiple NPCthe sentences of dialog overlaps with other npcs…For eg. if NPC1 has the script with its dialogues and NPC2 has the same script with different dialogues…I found out that the script glitches and mixes up the dialogues…
Could anyone help me…thanks in advance,

No…it’s the same…but we are using this script two times in each NPC…as we wanted to each NPC to have 2 dialogue as let’s say:
1.Real (script with keydown F)
2. Thought( script with keydown E)
It always works with the first NPC but glitches on other ones
And these two versions have different gui the real and thought
