Stick It to the Stickman is a 2D physics animation and stop-motion creation software designed specifically for the Mac platform. Centered around its intuitive “stick figure” character system, it combines a powerful physics engine with frame-by-frame animation tools, enabling users to quickly create expressive dynamic scenes. Whether you’re making simple physics simulations, game prototypes, or complex narrative animations, it provides a lightweight yet powerful working environment.

I. Detailed Overview of the Core Interface and Workspace

The main interface follows a clean and efficient design philosophy, primarily divided into five functional areas:

Top Menu Bar and Toolbar: Contains global commands such as file management, editing, view, and animation controls. The toolbar provides quick access to tools such as the brush, selection, joints, and physics properties.
Left Tool Panel: Core creation tools are arranged vertically, from top to bottom as follows:
- Selection Tool (V): Select and transform any element in the scene.
- Brush Tool (B): Draw stick figure limbs, props, or background elements.
- Joint Tool (J): Create hinge, pivot, or fixed joints between limbs to define physical connection relationships.
- Physics Properties Tool (P): Set physical parameters such as mass, friction, and elasticity for selected objects.
Center Canvas (Workspace): This is the main area for animation creation and preview. It displays the current frame, where you can directly draw, place characters, and props. The canvas supports zooming (Command + Scroll Wheel) and panning (hold Spacebar and drag).
Right-side Properties/Layers Panel:
- Properties Panel: When an element on the canvas is selected, its detailed parameters (such as position, rotation, color, and physics state) are displayed here, allowing for precise adjustments.
- Layers Panel: Manages all elements in the scene (characters, props, backgrounds) in a list format, allowing you to adjust stacking order, show/hide, or lock them.
Bottom Timeline and Animation Controls:
- Timeline: Displays the sequence of frames horizontally. Keyframes are marked with diamond icons. You can add, delete, or move keyframes here.
- Controls: Includes animation preview controls such as play/pause, jump to first/last frame, and loop playback, as well as the current frame indicator.

Tip: You can freely show or hide individual panels via the “Window” menu to suit different workflows. Using the Tab key to quickly toggle the visibility of tool panels is recommended.

II. Complete Workflow: From Creation to Export

Step 1: Create or Open a Project

After launching the software, select “File” > “New” (Command+N) to create a blank project. The system will preset a basic scene containing ground physics properties. To open an existing project, use “File” > “Open” (Command+O).

Step 2: Draw and Build the Character

Select the Brush Tool (B) in the left panel.
Click and drag on the canvas to draw each limb of the stick figure (e.g., head, torso, four limbs). Each time you release the mouse, a separate rigid line segment will be created.
Switch to the Joint Tool (J), click the endpoint of one limb, then drag and connect it to the endpoint of another limb to create a physical joint between them. The joint type (e.g., rotatable, fixed) can be adjusted in the properties panel on the right.

Step 3: Set Physics Properties and Initial State

Use the Selection Tool (V) to click and select a limb or prop.
In the Properties panel on the right, find the “Physics” section, where you can adjust mass, density, friction, and elasticity (restitution), etc. For example, increasing the friction of the feet can prevent slipping.
At frame 1 of the timeline, adjust the character’s pose and position; this will be the starting state of the animation.

Step 4: Create the animation (keyframe method or physics simulation)

Method A: Keyframe animation

Move the timeline playhead to the target frame (e.g., frame 24).
Use the selection tool on the canvas to move or rotate the character’s limbs and change their pose. The software will automatically create keyframes for the modified limbs at the current frame on the timeline (diamond markers will appear).
Repeat this process to set key poses at different points in time. Play the animation (press Space) to check the tweening effect.

Method B: Physics simulation animation

Make sure the character’s joints and physics properties have been set properly.
On the timeline, right-click a keyframe of a limb at a certain frame and select “Convert to Physics Simulation Frame”. From this frame onward, the limb’s motion will be calculated entirely by the physics engine rather than by keyframe interpolation.
You can trigger physics motion by adding external forces (set instantaneous velocity or force in the Properties panel).

Step 5: Preview and Adjust

Use the Play button in the bottom control bar or press the Spacebar to preview the animation in real time on the canvas. When you spot an issue, you can go back to the corresponding frame and use the selection tool to adjust element positions or modify physics parameters. Use “Control” > “Step Forward/Backward” (Right Arrow/Left Arrow) to inspect frame by frame.

Step 6: Export the Final Product

Select “File” > “Export” (Command+E).
In the pop-up window, configure the export settings:
- Format: Typically choose MOV (video) or PNG sequence (for post-production compositing).
- Resolution and Frame Rate: Match your project settings or customize them.
- Time Range: Specify the start frame and end frame for export.
Click “Export”, choose a save path, and the final file will be generated.

III. Advanced Tips for Common Features

Quick Duplicate and Mirror: After selecting one or more elements, press Command+D to duplicate directly. In the properties panel, set the X-axis scale ratio to -1 to achieve a horizontal mirror, quickly creating symmetrical characters.
Layer Management for Efficiency: For complex scenes, separate the background, characters, and foreground props into different layers (operate in the layers panel on the right). You can individually lock or hide a layer to avoid accidental edits.
Combining keyframes with physics: In character jump animations, use keyframes for precise control of takeoff and landing, and switch to physics simulation during the airborne phase to make the motion trajectory more natural.
Using reference images: Via “File” > “Import as Background”, you can place action reference images or scene sketches on the bottom layer of the canvas to assist with drawing and animation production.
Batch editing keyframes: Box-select multiple keyframes on the timeline, then uniformly adjust their physics parameters in the properties panel (e.g., increase elasticity across the board) to save time on frame-by-frame edits.

IV. Common Issues and Solutions

Issue	Possible Cause	Solution
Character limbs jitter abnormally or clip through	Physics joints are set too loosely, or unreasonable mass/elasticity parameters cause numerical instability.	1. Check and tighten the rotation limits or stiffness of the joints. 2. Appropriately increase the mass of the relevant limbs, or reduce the elasticity coefficient. 3. Try slightly adjusting the “physics simulation substeps” in the advanced software settings.
Severe lag during animation playback	Too many physics-computed elements in the scene, or individual frames are too complex.	1. During preview, you can temporarily hide unnecessary complex elements in the layers panel. 2. When exporting the final video, lag usually does not occur because rendering is computed offline.
Unable to add keyframes to a certain limb	The limb may be locked, or its layer may be locked.	Check the layers panel on the right and make sure the “lock” icon (padlock) for the target element and its layer is not highlighted.
Exported video background is black	The default canvas background is transparent/black, and no background color or image has been set.	Before exporting, use the brush tool to draw a filled rectangle as the background, or set a solid color background via “Modify” > “Canvas Color”.
Keyboard shortcuts not working	May conflict with shortcuts in other software, or focus is not on the main canvas.	Click once on the canvas area to ensure it has focus. Check the system “Keyboard Shortcuts” settings for any conflicts.
