Physics Platformer Toolkit

This is a first-of-its-kind UE5 toolkit built to help you create your own Physics-based Platformer.

Whether you’re prototyping or building a full game, this pack gives you fully implemented characters (3rd Person and Side Scroller) with simulated capsule, weapons, equipment and 25+ physics-based gameplay elements.

Each asset is self-contained and can be used independently. Some of the assets can be configured per-instance in editor in order to create variation.

🆕 New version is out v1.1.1 :

Improvements to the physics-based 3rd Person Character

• Fixed character in-air facing when spawned with a different orientation

• Added input actions for all inputs

• Fixed and simplified camera horizontal and vertical shift

• Made Grab actor more self-contained

• Made grapple hook actor more self-contained

Released alpha version of Default 3rd Person Character compatibility

• Ported weapons to Default Third person Character

• Ported most equipment to Default Third person Character

  • Grapple is partially working (and switched the char capsule in physics simulation mode)

  • Jet Pack is working, but uses another implementation, not the actor component

  • All other equipment is working

• Created an example third person character with weapons and equipment on a separate map

Known issues

• Punch animation montage is not working

🆕 New version is out v1.1:

• Full release of 3rd Person Mode!

• Modularization of all weapons and equipment for 3rd Person Character

• Other 3rd Person Mode improvements

  • Simplified and cleaned up actor functions

  • Merged Grab and Physics Gun, to use a single component behind the scenes

  • Added animation and sphere trace for Punching

  • Added comments and units to equipment and weapons input parameters

🆕 New version is out v1.0.8:

• General improvements:

  • Added shortcut to switch between 3rd Person and Side Scroller levels

  • Fixed key mapping display

  • Fixed character not being able to walk on ground in a damping field

  • Fixed character not being able to walk on falling objects in a damping field

  • Fixed gravity being activated on objects in a damping field when it wasn't before

  • Fixed character still falling when in antigravity field

• Improvements for 3rd Person Mode:

  • Separated PhysicsGun and Grab handler components so we can customize them

  • Added switch to orient or not object to the camera for PhysicsGun and Grab

  • Tweaked the Physics Gun constraint to make it feel more stable and sturdy

  • Fixed Grab not highlighting bigger objects entirely

     

🆕 New version is out v1.0.7:

• Beta release of 3rd Person Mode

   

🆕 New version is out v1.0.4:

• Fixed rocket stabilization issue

• Implemented an additional rocket version which slides instead of turning in force fields

⚠️ Important Notes

• This toolkit needs State Tree UE5 plugin (see technical details).

• This toolkit is focused on the physics simulation. The meshes, materials and effects are not the main focus of the pack, they are only provided in order to showcase the physics assets.

• Physics simulation is usually unpredictable. While assets are designed to be reliable in most scenarios, some specific cases may require custom adjustments on your end.

• Blueprints implementation only (no C++)

• Not tested in VR.

• Not tested in multiplayer.

🐞Known issues

• The grapple hook visual representation is not correctly updated when latching onto a geometry collection. But the grapple does in fact work. There's currently no way to get the location of a part of a geometry collection in Blueprints.

• In a physics field, physics constraints break if one of the attached components goes to sleep. It seems to be an engine bug. The workaround used is a Physical Material which doesn't sleep, applied on the components affected by the field.
