Update (04/04/2022) I fixed the zip file. Everything should be working now. Thank you for making me aware of the issue. This is interactable button using AvatarDynamics: Proximity Contact Receiver. This is meant for Avatars only! Pressing down the button (Using Hands, Legs or Head) plays the sound. Easy to customize the sound and texture! Optimized! ◆ Requirements: * Latest VRCSDK for Avatars that has AvatarDynamics / Physbones. ◆ How to add this to your Avatar (Requires Basic Unity Knowledge): 1) Drag the Button.prefab into your Avatar scene. 2) Put the prefab inside your avatar. 3) Inside the prefab, there is a GameObject "Button_ParentConstraint", put that inside your Left Hand Bone. 4) Position and scale the button, so it does not collide with your hand. 5) To add animations, check out "Example_FX" controller and try to copy and paste it to your Avatar's FX controller. Animations are already made in "Animations" Folder. 6) To add parameters, check out "Example_Parameters" asset and try to copy and paste it to your Avatar's Parameters. 7) Add a button to your Avatar's Menu. Use "Button_Toggle" Parameter for that and change the Type to "Toggle". 8) You are good to go! ◆ If you have issues with this, feel free to contact me!
