Rigidbody2D.constraints. Apparently doesn't exist. Missing directive?

public RigidbodyConstraints2D constraints;
Description
Controls which degrees of freedom are allowed for the simulation of this Rigidbody2D.

GetComponent<Rigidbody2D>().constraints.FreezePositionY();

Assets/Scripts/Block.cs(47,53): error CS1061: Type UnityEngine.Rigidbody2D' does not contain a definition for constraints’ and no extension method constraints' of type UnityEngine.Rigidbody2D’ could be found (are you missing a using directive or an assembly reference?)

So… Missing directive?

It seems the syntax goes about:

GetComponent<Rigidbody2D>().constraints = RigidbodyConstraints2D.FreezePositionY;

If it complains about “constraints” you can try restarting Unity and/or Visual studio.

I actually use monodev. Still. [:P]

Is this a post Unity 5.0 feature? That would explain the missing reference.

While the error message is a little misleading you were getting it in the first place because your syntax was incorrect. The RigidbodyConstraints2D enum was added at the same time as Rigidbody2D and is syntactically consistent with Rigidbody and RigidbodyConstraints.

@Bionicle_fanatic

Is this a post Unity 5.0 feature? That would explain the missing reference.

It was added with Unity 5.3.4. That said your code is still incorrect because it’s an enumeration not a method.

[KelsoMRK]

I was mistaken. You’re using an older version of Unity AND your syntax is incorrect

[Bionicle_fanatic]

Ahhhh… So I either have to constrain it via transform, or upgrade (Which in doing so would incur a plethora of problems).

Thanks for the help, guys. [:)]
