Use a movement preset

SUCC ships five ready-made movement feels in addons/SUCC/resources/. Each is a SUCCConfig resource. Swapping one changes gravity, speed, friction, jump height, hull size and eye height together.

Pick one

File	Feels like	Pick it when
default_config.tres	SurfsUp	You want fast, slidey surf movement. The quickest of the five.
goldsrc.tres	Half-Life, Counter-Strike 1.6	You want the bhop feel most players recognise.
quake.tres	Quake, QuakeWorld	You want strafe-jumping and a shorter, lower-slung character.
quake2.tres	Quake 2	You want heavier, grippier movement with no air control.
source.tres	Half-Life 2	You want floaty jumps, a walk/sprint split, and slower ground speed.

For the exact numbers see Preset values. For where they come from, see How accurate are the presets?.

Assign one in the editor

1. Select your SUCC character node.
2. In the Inspector, find the Config property.
3. Click the folder icon and choose one of the five .tres files.

Run the scene.

Swap one while the game is running

Assign the new config, then call apply_config(). The second call rebuilds the collision shape, the floor snap distance and the camera height from the new values. Without it your character keeps the old body.

const QUAKE: SUCCConfig = preload("res://addons/SUCC/resources/quake.tres")


func switch_to_quake() -> void:
    config = QUAKE
    apply_config()

Swapping resets the crouch state, so a crouched character stands up.

Offer presets as a menu

Presets are plain resources, so a settings screen is just a list of paths:

const PRESETS: Array[String] = [
    "res://addons/SUCC/resources/default_config.tres",
    "res://addons/SUCC/resources/goldsrc.tres",
    "res://addons/SUCC/resources/quake.tres",
    "res://addons/SUCC/resources/quake2.tres",
    "res://addons/SUCC/resources/source.tres",
]


func apply_preset(index: int) -> void:
    var picked: SUCCConfig = load(PRESETS[index]) as SUCCConfig
    if picked == null:
        push_error("Could not load preset %d" % index)
        return
    config = picked
    apply_config()

The demo level does this on keys 1-5. See addons/SUCC/demo/test_level.gd for a working version with a HUD readout.

Turn off surf handling

enable_surf is on by default. It projects air acceleration along steep ramp faces so you can gain and hold speed while surfing. Surf ramps remain airborne and ignore jump input until you reach a walkable floor.

To use ordinary airborne acceleration on steep faces instead, turn it off:

enable_surf = false

Leave it on if you want surf ramps to work the way surf maps expect.

Don't edit the shipped files

Editing goldsrc.tres in place means the next addon update overwrites your changes, and the file no longer matches its name. Duplicate it first, then edit the copy - see Tune your own movement.
