Probe

A free, zero-setup runtime tuning console for Unity.

Watch live values, run commands, tweak variables with sliders, and save your tuning as presets. Drop it into a Unity project, press Play, and Probe is already there.

Now on the Unity Asset Store — same package, one-click import.

Why Probe

Probe is not just an in-game log console. It is a tiny runtime tuning workflow:

• Zero setup: no prefab, no scene setup, no manager object to wire.
• Console commands: mark methods with [DebugCommand].
• Live panel: FPS, memory, and custom watches.
• Debug buttons: one-tap QA actions with [DebugButton].
• Live sliders: tune numeric values with [DebugTweak].
• Tweak presets: save, load, reset, and share slider values as JSON.
• Build-safe by default: auto-starts only in Editor and Development builds unless enabled.

Tweak Presets

Tune values in Play Mode, save the feel, break it on purpose, then load it back.

Panel buttons use a quick preset slot:

• Save: store current slider values.
• Load: restore the quick preset.
• Reset: return to startup defaults.

Console commands support named presets:

preset_save floaty_jump
preset_load floaty_jump
preset_list
preset_reset

Presets are saved as JSON under Application.persistentDataPath/ProbePresets.

Quick Start

1. Copy Assets/Probe into your Unity project.
2. Press Play.
3. Open the console with the backquote key ` or the on-screen </> button.
4. Type help.

For a guided demo, add ProbeDemo from Assets/Probe/Demo to an empty GameObject and press Play.

Examples

Console Command

usingProbe;publicstaticclassCheats{[DebugCommand("give_gold","Add gold to the player")]staticstringGiveGold(intamount){Player.Gold+=amount;return$"Gold is now {Player.Gold}";}}

Then type:

give_gold 500

Live Watch

ProbePanel.Watch("HP",()=>player.health);ProbePanel.Watch("State",()=>enemy.currentState);

Runtime Slider

publicclassMovement:MonoBehaviour{voidAwake()=>ProbeTweaks.RegisterInstance(this);voidOnDestroy()=>ProbeTweaks.UnregisterInstance(this);[DebugTweak(0f,20f)]publicfloatmoveSpeed=5f;}

One-Tap Button

[DebugButton("Full Heal")]voidFullHeal()=>health=maxHealth;

Build Safety

Probe auto-starts in the Unity Editor and Development builds.

Use scripting define symbols to override:

Symbol	Behavior
PROBE_ENABLE	Force Probe on, even in release builds
PROBE_DISABLE	Force Probe off everywhere

Probe is debug tooling. For production builds, keep it disabled unless you intentionally want runtime debug access.
