I'm learning Houdini. And I'm getting my feet wet with vex. The problem I'm having is I don't understand how to get good feedback on the code I'm writing. In previous scripting environments I have worked with, the good ones have an easy way to print messages for debugging. With Houdini and vex this seems to be mysterious. I can't find how to open the console. I have made the console appear in vops using the print node and ticking the open text to console check box. But I haven't been able to get any useful feed back from vex. The documentaion has a print function which says it prints to the console. I can't make this work. I guess I don't understand when the code is compiled or run. for instance in a attribwrangle if I put the following code: string a = "hello"; print("label", a); nothing happens. I tried playing the timeline. not sure how to make this work. I have also tried: string a = "hello"; printf("%s\n", a); I'm obviously confused here and would appreciate a point in the right direction on how to make vex print messages to the console. thanks a lot.
