MOST Editor

A plug-and-play Unity editor bundle of attributes, drawers, and utility structs that supercharge inspectors—no custom editor boilerplate needed.

Attribute drawers that hide/disable fields depend on the compared properties being serialized (public or [SerializeField]).

You may stack multiple drawers per property/field ([Line, HideIf, ReadOnly] public)

MOSTRange (Property)

1) Quick Definition

Serializable struct storing a Min/Max float pair with built‑in order safety (Min ≤ Max) and GetRandomValue().

2) Example

// Define a MOSTRange property
[Tooltip("Base damage range in HP")] 
public MOSTRange BaseDamage = new(5f, 12f);

// ____ Usecase ____
BaseDamage.GetRandomValue();
// return a random float value between 5 and 12

BaseDamage.Min
// return or set the minimum value of the BaseDamage
// The min/max values will be recalculated after any of BaseDamage values are edited
// In case the entered minimum value is bigger than the max value...

//Exampe
BaseDamage.Min = 15;
// now min will become 12 and max = 15..

BaseDamage.Max
// return or set the maximum value of the BaseDamage
// The min/max values will be recalculated after any of BaseDamage values are edited
// In case the entered maximum value is smaller than the max value...

//Exampe
BaseDamage.Max = 3;
// now min will become 3 and max = 5..

3) What You’ll See in the Inspector

Single line with two labeled float fields: Min | Max. Values auto-correct when swapped.

MinMaxSlider (Attribute)

1) Quick Definition

Draws a float range editor with numeric fields and a MinMaxSlider. Hard limits may be constants or resolved from sibling properties. require MOSTRange

2) Example

// A) Both limits are constants
[MinMaxSlider(0f, 100f)] // slider clamps to [0, 100]
public MOSTRange volumeDb;


// B) Both limits come from sibling fields (by name)
public float minLimit = 0f; // must be serialized
public float maxLimit = 1f; // must be serialized
[MinMaxSlider(nameof(minLimit), nameof(maxLimit))]
public MOSTRange threshold;


// C) Min from ref, Max constant
public float floor = -10f;
[MinMaxSlider(nameof(floor), 10f)]
public MOSTRange clipRange;


// D) Min constant, Max from ref
public float ceiling = 2f;
[MinMaxSlider(0f, nameof(ceiling))]
public MOSTRange normalized;

3) What You’ll See in the Inspector

A slider min/max with values clamped to the resolved hard limits.

MOSTRangeInt (Property)

// ____ Usecase ____
BaseDamage.GetRandomValue();
// return a random Int value between 5 and 12

BaseDamage.Min
// return or set the minimum value of the BaseDamage
// The min/max values will be recalculated after any of BaseDamage values are edited
// In case the entered minimum value is bigger than the max value...

//Exampe
BaseDamage.Min = 15;
// now min will become 12 and max = 15..

BaseDamage.Max
// return or set the maximum value of the BaseDamage
// The min/max values will be recalculated after any of BaseDamage values are edited
// In case the entered maximum value is smaller than the max value...

//Exampe

}


[HideScriptField]
public class MyAsset : ScriptableObject
