How to add colliders to scripts at runtime?

[Estigio97]

Hello, I have been implementing a weapon exchange system by instantiating them at runtime. I manage to relate the parameters that the controller needs so that my sword (in my case) works correctly. But, when I try to add the sword colliders to the colliders list of the ThirdPersonMeleeWeaponProperties script, I create an array of MeleeHitbox and try to assign the collider in its property, and then add this array to the corresponding variable of the script, but being a property read-only, I cannot overwrite or change anything of that property. How can I add these colliders at runtime to this array?

These gives me an error:
NullReferenceException: Object reference not set to an instance of an object

The ThirdPersonMeleeWeaponProperties has a public getter property so you can assign those at runtime. After you set the hitbox make sure you initialize it to the character transform.
