SimWalk

SimWalk gives you direct, real-time keyboard control of your active Sim — walk them around your lot with WASD, like steering a character in an action game, instead of click-to-route. Movement is smooth and collision-aware, the camera stays your point of reference, and doors and stairs are handled automatically as you walk into them. This update also brings a real, noticeable reduction in stutter/hitching, a fix for the camera losing track of your Sim mid-walk, and corrected animation scaling for Teens — see below for details.

How is this different from Victor Andrade's Direct Controls? SimWalk was inspired by Victor's pioneering work and tackles the same dream — but it's an independent build with its own focus, especially on feel and control in tight spaces:

• Smooth, threaded movement in real furniture. SimWalk uses a reduced-radius collision approach so your Sim can slip through the gaps you'd expect to fit through — between a couch and coffee table, along a pool edge, down a narrow kitchen aisle — instead of snagging on invisible footprints.
• Smart, directional doorways. Doors, arches, and stairs only "grab" you when you're actually heading through them — walk past a doorway and it leaves you alone.
• An in-game pop-up settings menu (F9). Enable/disable and live-tune everything — speed, collision squeeze, door behavior, hotkey — without touching the console.

Installation instructions

1. In-game, go to Game Options → Other and make sure Enable Custom Content and Mods and Script Mods Allowed are both checked. Restart the game if you just enabled them.
2. Download and unzip the mod.
3. Place both files — SimWalk.package and SimWalk.ts4script — directly into your Mods folder: Documents\Electronic Arts\The Sims 4\Mods. Keep them no more than one sub-folder deep.
4. Start the game and load a household.

Localization

SimWalk's F9 settings menu is available in English, Simplified Chinese and Brazilian Portugeuse (separate download). If you'd like SimWalk translated into another language, please post/comment on the mod page.

Main features

• Direct WASD control of your active Sim, relative to the camera.
• Toggle control on/off with Left Alt (rebindable).
• Smooth, collision-aware movement that threads tight furniture gaps naturally.
• Automatic doors, stairs & arches — walk through them normally; they won't catch you when you're just passing by.
• Camera stays locked on your Sim while walking, so it won't drift away or lose track mid-move — makes it easy to click a pie-menu option without losing your place. (The camera is free to pan normally whenever you're standing still with control on.)
• F9 pop-up settings menu — enable/disable, and adjust walk speed, collision clearance, door catch sensitivity, door re-engage distance, camera lock, and the toggle key all live in-game.

Performance & Animation Update (this version)

This update focuses on reducing the stutter/hitching that could happen during movement, especially in busy or heavily-decorated areas, plus a couple of real bug fixes. After a deep dive into what was actually costing time under the hood, several real, confirmed sources of hitching were found and fixed:

• Smoother movement in crowded areas. Found and fixed an inefficiency in how the game assigns Sims to nearby social situations — it was scanning every Sim in the zone far more often than necessary. Busier lots should now feel noticeably smoother.
• Reduced background housekeeping overhead. Several behind-the-scenes systems (social clustering, background events, weather/seasons processing) were giving themselves overly generous time budgets on every single game tick, whether they needed it or not. These are now trimmed down while SimWalk is active.
• Cleaned up memory housekeeping. Found a build-up of stale, already-finished scheduling entries that weren't being cleared out as often as they should have been, adding unnecessary overhead to the game's core simulation loop.
• Faster, snappier turning. Turn speed and turn responsiveness have been increased based on live testing — direction changes now feel quicker and less sluggish.
• Fixed: camera losing track of your Sim while walking. Moving your mouse (e.g. to click a pie-menu option) used to disconnect the camera from following your Sim. It now stays locked on while you're actively moving.
• Fixed: stretched legs on Teen Sims. Teens were missing a piece of animation data the game needs to correctly scale movement to their body — corrected, and Teen movement should now look normal.

Combined, these changes produce a real, noticeable reduction in stutter frequency and severity, particularly in populated areas. Some residual hitching in very large or densely-populated zones is expected — that portion comes from the base game's own simulation engine handling everything happening in a zone at once, which is outside what any script mod can fully control.

Known Limitations

• Child/Toddlers/Infants Sims will show stretched/distorted leg animations while under SimWalk control. This is a deeper animation-engine issue (These use a fundamentally different walk-animation system than Teens/Adults/Elders) and is not currently fixable without building all-new animation content from scratch.
• Windows only (see Requirements below) — Mac support is shelved until I can find a Mac tester.

Requirements

• The Sims 4 base game.
• Script Mods must be enabled (see Installation, step 1).
• Windows — SimWalk uses a Windows keyboard hook for real-time input, so it is Windows-only.
• No other mods required.

Shout outs

Victor Andrade — SimWalk exists because Victor first showed the community that direct, keyboard-driven control of a Sim was possible. His work was the inspiration for this project, and this mod is offered with gratitude and respect for his memory.
