How Sonic or other objects react to the collision geometry inside of the game relies on certain extra properties assigned during conversion to the individual Havok rigid bodies.

Havok Converter supports adding these properties to custom rigid bodies with a tag naming system. New tags and key/value pairs can be added to the program as needed.

Havok Property Keys

All these keys were found and documented by various users by inspecting the collision files found in the game. Just because a key or a value doesn't show up here doesn't mean the game can't use it. Thankfully a user by the name of Sergeanur helped figure out that the keys were just hashes.

Player Collision

• swa_col_player

Camera Collision

• swa_col_camera
• Key 1706239430
• Setting this set to 1 will not let the camera go through collision which is default when exported. 0 will make allow the camera to go through it.

Other Collision

• swa_col_other
• Key 620872783
• This also is set to 1 on default. Setting it to 0 will allow Object Physics and other objects that aren't Sonic or Enemies go through. Useful for object physics to go and break outside of areas sonic can't go to.

Attacking Collision

• swa_col_attacking
• Key 1651585625

Evil Balance/Classic Idle Edge

• swa_evil_isbalance_ground
• Key 122999549
• This is used for Werehog in Unleashed for the balancing beams but turns out it is also used for Classic Sonic as well when tested in Werehog Level Collision

Wall Jump -Unleashed Only

• swa_sonic_isplayerwalljump
• Key 507440184
• Setting this to 1 will let any wall be able to walljump. Generations doesn't use this you just need to place the triangle jumping collision in an area where you want to walljump instead.

Conveyor Belt

• swa_sonic_isbeltconveyor
• Key 1196263925
• Use 'Egg_BeltCollisionSV', 'Egg_BeltCollision' objects in Unleashed. Use 'BeltConveyorCollision' object in Generations
