Guys i need help figuring something out, how do i add a dialogue that will play when a character is doing an animation that triggers with a specific item use? I'm trying to make my outpost more alive by having characters say some things when doing certain stuff but i can't for the life of my figure out how to do that, think for example of the peeler machine when they are screaming AHHH that triggers by the machine use i want to do something similar so i can add dialogues
