I keep getting an unknown parameter for createRevoluteJoint. I can't figure it out. Not sure if it has to do with my array or not.

Quote: "CreateRevoluteJoint ( 11, 6, 42, 25)"


definition of createrevolutejoint:

CreateRevoluteJoint( iJointIndex, iSpriteIndex1, iSpriteIndex2, x, y, colConnected )

OR

integer CreateRevoluteJoint( iSpriteIndex1, iSpriteIndex2, x, y, colConnected )

So, you should do:

CreateRevoluteJoint( 1, 11, rope[6], X, Y, 1 )

If that's what you wanted to attach it to, because I don't see any sprite creation under number 6.

The "unknown parameter" error comes up if you use too few parameters as well as if you use too many.

You either need to specify the joint number as the first parameter or let AppGameKit assign a joint number as kamac has said.

Thanks guys. I was following this guide

http://www.appgamekit.com/documentation/examples/physics/7_joints2.htm

It fails to mention the joint index.

Kamac, I have SpriteI handling one through five. Just don't ask why I have two arrays to handle this when I could have one it with one.

Yah, that code at the end of the guide won't compile. And it has more problems than just the missing parameter for creating the joint.

Looks like a typo and untested example, if you can report the link and error to the issues board (http://code.google.com/p/agk/issues/list), that would be great, thanks!

I drink tea, and in my spare time I write software.
