<cat>Dev.Entities</cat> Entities based on `BaseAnimatingOverlay` are capable of layering animations. <page>NextBot</page>s and <page>Player</page>s are `BaseAnimatingOverlay` entities. Only <page>Scripted Entities</page> of the `anim` type are `BaseAnimatingOverlay`. <note>Playing gestures/creating new layers on <page>NextBot</page>s may not work correctly unless done in the <page>NEXTBOT:BehaveUpdate</page> hook.</note> The following functions can only be used on **BaseAnimatingOverlay** entities: * Layer creation functions * <page>Entity:AddGesture</page> * <page>Entity:AddGestureSequence</page> * <page>Entity:AddLayeredSequence</page> * Layer manipulation functions * <page>Entity:IsValidLayer</page> * <page>Entity:SetLayerDuration</page> * <page>Entity:GetLayerDuration</page> * <page>Entity:SetLayerCycle</page> * <page>Entity:GetLayerCycle</page> * <page>Entity:SetLayerPlaybackRate</page> * <page>Entity:SetLayerWeight</page> * <page>Entity:GetLayerWeight</page> * <page>Entity:SetLayerBlendIn</page> * <page>Entity:SetLayerBlendOut</page> * <page>Entity:SetLayerLooping</page> * Other functions * <page>Entity:IsPlayingGesture</page> * <page>Entity:RestartGesture</page> * <page>Entity:RemoveGesture</page> * <page>Entity:RemoveAllGestures</page> ⤶ ⤶ <example>⤶ <description>⤶ Example usage of layers on a `anim` type SENT.⤶ </description>⤶ <code>⤶ AddCSLuaFile()⤶ DEFINE_BASECLASS( "base_gmodentity" )⤶ ⤶ ENT.PrintName = "Example Animated Overlay"⤶ ENT.AutomaticFrameAdvance = true⤶ ⤶ function ENT:Initialize()⤶ ⤶ if ( SERVER ) then⤶ ⤶ -- Basic set up - a model with animations and physics mode so it doesn't fall over for demonstration⤶ self:SetModel( "models/alyx.mdl" )⤶ self:PhysicsInit( SOLID_OBB )⤶ ⤶ self:ResetSequence( "walk_all" ) -- Base sequence, walking⤶ self:SetPoseParameter( "move_yaw", 90 ) -- Affects how the base sequence looks⤶ ⤶ -- Overlayed sequence on top of base animation, move the head⤶ -- false at the end to not kill the animation after it plays once.⤶ self.LayerID = self:AddGestureSequence( self:LookupSequence( "a_bg_lookupright" ), false )⤶ self:SetLayerLooping( self.LayerID, true ) -- Loop the layer⤶ ⤶ ⤶ ⤶ end⤶ ⤶ end⤶ ⤶ function ENT:Think()⤶ if ( SERVER ) then⤶ -- Do any logic with layers here, play them, stop them, etc.⤶ ⤶ -- Make sure the animation is smooth⤶ self:NextThink( CurTime() )⤶ return true⤶ end⤶ end⤶ ⤶ </code>⤶ </example>⤶
