<function name="SetParent" parent="Entity" type="classfunc"> <description> Sets the parent of this entity, making it move with its parent. This will make the child entity non solid, nothing can interact with them, including traces. Sets the parent of this entity, making it move with its parent. This will make the child entity non solid, nothing can interact with them, including traces (but <page>util.TraceHull</page> will work). All children of the parent get removed whenever it gets removed. <note>This does not work on <page text="the world">game.GetWorld</page>.</note> <warning>This can cause undefined physics behavior when used on entities that don't support parenting. See the [Valve developer wiki](https://developer.valvesoftware.com/wiki/Entity_Hierarchy_(parenting)) for more information.</warning> </description> <realm>Shared</realm> <args> <arg name="parent" type="Entity" default="NULL">The entity to parent to. Setting this to nil will clear the parent.</arg> <arg name="attachmentOrBoneId" type="number" default="-1">The attachment or bone id to use when parenting. Defaults to -1 or whatever the parent had set previously. Use <page>Entity:AddEffects</page>( EF_FOLLOWBONE ) to treat this argument as a Bone ID instead of an Attachment ID. Similar to <page>Entity:FollowBone</page>. <note>You must call <page>Entity:SetMoveType</page>( MOVETYPE_NONE ) on the child for this argument to have any effect!</note></arg> </args> </function>
