+# ClientSim
+## A VRChat Client Simulator for building Worlds
+
+This tool enables you to test your VRChat SDK3 Worlds directly in Unity! You can look at the state of all objects to verify things directly.
+
+## Features
+
+- Debug everything in Unity.
+- Inspect Udon variables in Play Mode.
+- Desktop player controller.
+- Grab Pickups, use Interacts, UI and Stations.
+- Delete EditorOnly objects on Play.
+
+### New Features in ClientSim
+- Pickup manipulation through I, J, K, L, U, O, mouse scrolling and gamepad.
+- Input based on keyboard layout instead of specific keys.
+- Local and Remote player now have humanoid avatars, avatar bones supported (but not full Avatar systems).
+- View and set player data directly - Locomotion values, voice and avatar audio settings, combat health.
+- Unlock mouse by holding tab - you can highlight off-center objects this way.
+- Pointer displays when a UI element can be interacted with.
+- New runtime options: start as non-master, invert mouse, show tooltips, change player scale, set target framerate, delay start to simulate loading.
+- New playmode menu with updated style, player info and settings buttons.
+- New buttons in the Settings Window to update Project Settings, no longer happens without user consent.
+- Mesh highlighting that matches Android.
+- Tooltip location updated to match client.
+- Better gamepad support.
+- Support for Disabled Domain Reload to enter playmode without delay - note that there is a Unity bug that causes UI Events to fail if they're not set to "Editor and Runtime".
+- Automated Testing - you need to specifically enable this so it won't affect your project. Documentation forthcoming.
+
+### Known Issues
+
+- Manually changing Unity Project settings to enable the new input system may not properly allow input. Users should use the buttons in the ClientSim Settings Window.
+- Physics.RaycastNonAlloc sometimes does not return colliders that have moved and do not have rigidbodies.
+- On exiting playmode may throw exceptions occasionally due to order in which objects are destroyed.
+- Highlight shader does not work on Mac (Metal).
+
