Which attribute restricts a public variable to a maximum of 100 in Unity?

The Range attribute is used in Unity to specify a minimum and maximum limit for a variable, particularly when it's exposed in the Inspector. When applied to a public variable, it allows developers to define a specific range that the variable can take, in this case, restricting it to a maximum value of 100.

For example, if you have a public variable defined as:

[Range(0, 100)]

public float myVariable;

This setup ensures that whenever someone tries to modify myVariable in the Unity Inspector, they can only select values between 0 and 100. This is particularly useful in Unity for ensuring that values stay within a desirable range to prevent unexpected behavior during gameplay, such as ensuring player health or speed does not exceed set thresholds.

Other attributes listed such as Min, Clamp, and Limit do not serve the same purpose in Unity. Min is used solely to define a minimum value, Clamp is not an attribute you apply to public variables for inspector limits but rather a method to constrain values at runtime, and Limit is not a recognized attribute in Unity. Thus, the Range attribute is the appropriate choice for enforcing maximum (and minimum) limits on public variables.
