Unity 3D Game Engine – Stealth Game – Single Doors – JS
Load prefab:
-> (parent) ‘door_generic_slide’
|Animator – Closed animation, Open animation inside are inside fbx file
|SingleDoorAnimator – uncheck Apply Root Motion – parameter bool: open – transitions: open->close close->open
|Sphere Collider – check ‘Is Trigger’ (to check player position)
|Audio Source Component (doorSwishClip + accessDeniedClip), uncheck ‘Play on Awake’
|DoorAnimation.js
–> (child) ‘door_generic_slide_panel’
|Mesh Renderer, check ‘Use Light Probes’
|Box Collider (to block the player penetration)
|Rigid Body, uncheck ‘Use Gravity’, check ‘Is Kinematic’ (to block the player penetration)
