DonXin - Automatic Retractable Doors

Interactive Retractable Door — Animation Sequence / Control Rig

A skeletal retractable door asset designed for industrial parks, warehouses, factories, and building entrances. Includes two independent setups: a collision-triggered Blueprint version and a Control Rig version for Level Sequences, suitable for gameplay interaction and cinematic animation.

Collision-Triggered Blueprint Version

Quickly create automatic door interactions with BP_RetractableDoor01.

  • Opens when a Pawn enters the trigger area and closes when the last Pawn leaves.

  • Can reverse direction at any point, continuing from the current animation progress for smooth pose continuity.

  • Supports separate opening and closing playback speeds.

  • Automatic triggering can be disabled for external control through variables.

  • The animation control curve is embedded in the Blueprint Timeline for convenient inspection and adjustment.

Control Rig Version

Adjust the door’s opening position and width using two easily identifiable, ground-level controls.

  • CTRL_A_Door: Controls door extension, retraction, opening, and closing.

  • CTRL_B_Width: Adjusts the position of the opposite fixing post to accommodate different entrance widths.

  • Control A is constrained by Control B, limiting the door’s maximum extension.

  • Uprights and scissor linkages move together as the door extends and retracts.

  • Controls can be keyframed in Sequencer to create opening and closing animations.

Included Content
  • Skeletal meshes, skeletons, and physics assets

  • Materials, material instances, and textures

  • Opening animation and interaction Blueprint

  • Control Rig and a demo Level Sequence

  • A separate preview level for each version

  • Includes Blender5.2 file

The two setups are organized in separate folders, allowing you to choose the version that suits your project.

交互式伸缩门—动画序列/Control Rig

为工业园区、仓库、工厂及建筑入口制作的骨骼伸缩门资源,包含两套独立方案:碰撞触发蓝图版与 Control Rig 关卡序列控制版,分别适用于游戏交互和关卡序列动画制作。

碰撞触发蓝图版

使用 BP_RetractableDoor01 快速搭建自动门交互。

  • Pawn 进入触发区域时开门,最后一名 Pawn 离开后关门。

  • 开关门过程中可随时反向,从当前进度继续运动,保持姿态连续。

  • 支持分别调整开门与关门播放速度。

  • 可关闭自动触发,通过 变量 从外部控制。

  • 动画控制曲线内嵌于蓝图时间轴,便于集中查看和调整。

Control Rig 控制版

通过两个易于识别和选择的地面控制器,调整门的开合状态与适配宽度。

  • CTRL_A_Door:控制门体伸缩与开合。

  • CTRL_B_Width:调整另一端固定立柱的位置,适配不同入口宽度。

  • A 控制器受 B 控制器限定,约束门的最大展开范围。

  • 立柱与交叉连杆随门体伸缩联动。

  • 可在 Sequencer 中为控制器设置关键帧,制作开关门演出。

包含内容
  • 骨骼网格体、骨架及物理资产

  • 材质、材质实例与贴图

  • 开门动画及交互蓝图

  • Control Rig 与演示关卡序列

  • 两套资源各自的预览关卡

  • 附送blender5.2源文件

两套方案分目录组织,可根据项目需要选用。
