ParentConstraint usage

(Fair warning, I'm still very nooby when it comes to c# and unity so there's a good chance I'm using the wrong terms for things here, please bear with me) I'm trying to create a flying enemy in a 2D platformer that will get grabbed by the player on collision. The enemy will also slow the player's fall allowing them to span bigger gaps. However, I have no I idea how to activate the patent constraint in a script. I think this is because I don't know how to declare an object to use it with. How do I declare an object in a way that lets me use parent constraint?

 

Unity has pretty decent documentation on a lot of their stuff, did you try viewing the page on ParentConstraint? It tells you all the properties and methods you can access through code, gives a description of what each does, and sometimes even has examples of how to use them.

 

I did, the issue is I'm not sure how to reference the ParentConstraint from the object.

 

Can you not just use GetComponent on the object, like you would for any other component?

 

I just get an error message saying GameObject does not contain a definition for ParentConstraint.

 

Each GameObject does not inherently know what components it has, so you have to either use the method GetComponent to check for one, or to assign it in the Inspector. You cannot just try to access it like a property, which is what I'm guessing you're doing.

Code (CSharp):

1. ParentConstraint pc = GetComponent<ParentConstraint>(); // <-- works
2.  
3. ParentConstraint pc = gameObject.ParentConstraint; // <-- bad, won't work

 

do you by any chance know what to do if this doesnt work

unity insists that ParentConstraint doesnt exist, like in: the type doesnt exist not the variable

 

Did you make sure to include the libaries ParentConstraint is from? If you're using Visual Studio or some other good IDE it should auto-fill it in for you.

I would also recommend not necro-ing an old post, your problem isn't the same as the one above. Instead, you can just create a new thread. When doing so, I'd recommend making sure your post is as detailed as possible, as you have not given a lot of information. A sample of your code would be a good starting place. If you do decide to share code, please make sure to use code tags, which you can find how to use on the top sticky thread of this forum.
