[Closed] CSolver Simple Problem

Ahh… simple mistake!

  You're asking max to execute the global function "addConstraint" (see "Controller Functions for use with Constraint Assignments" in the help") which expects 4 arguments...
  
  ...as opposed to the cSolvers's method (function) "addConstraint" which expects 1 argument. If you change the last line of your script to...

MyCSolver.Addconstraint MyPcont

  ...it should all work fine.
  
  
  Basically, any object that has an "Interface" or "Interfaces" takes it's object name first, followed by the method (function) name, then it's arguments:

objectNameOrType.methodName argument1 argument2 argumentN

  It's not that clear to people first starting out in max script (Understanding the structure of a function or method in the help file isn't that clear unless you have programming experience, or have read "How do I understand the function definitions in this document?" in the help), but that's the key thing.
 
 You can see all the accessible properties and functions of an object (if it has any) with the following command:

showInterfaces $
     
       Interface: rctConstraintSolverInterface
        Properties:
     	.constraints : node by value array : Read|Write
     	.rbCollection : node : Read|Write
     	.isDisabled : boolean : Read|Write
     	.deactivationThreshold : float : Read|Write
        Methods:
     	<boolean>addConstraint newConstraint
     	<boolean>removeConstraintIndex index
     	<boolean>removeConstraint deletedConstraint
     	<integer>getNumConstraints()
     	<boolean>isValid()
        Actions:

 Does that make it clear!?

Hi Dave

One day I must read the whole manual, im sure it will make sense then

Believe it or not that was what I was looking for in the manual but couldnt find it. I ususaly use ShowProperties when looking for that information but forgot to even try it in this case…

Thanks a lot.
