trouble shooting techniques

[rubes]

What techniques do you use to troubleshoot issues in mmf?

I have an app that I'm working on, and one of the things I need to check is what is overlapping what else. I have this working in a stand alone mmf, but when I try to apply this to the bigger app, it is not working as desired. I have rewritten the logic a few times, and I know the fundamentals are sound from my stand alone test. I'm curious how others go about troubleshooting when experiencing these sorts of things.

thanks,

I use 3 different techniques for debugging/troubleshooting.
1. strings, many strings. If i try to debug specific objects I create string at each of them that display their values. it helps me to examine how their values change over time or I can spot values that looks wrong.
2. tracing with List object. I place big list object somewhere on the screen and in the code I print messages that will help me trace how and in what order are my action execute. Result can then look something like this " setting value of object a, jumping to x, in loop x...."
3. Debug drawing on surface object. I use this if I want to visualize relations between objects. For example if i mouse over one object it will draw lines to all object that are in line of sight or something similar.

Good stuff BigHatLogan. I have used strings and counters, and was just pondering a list object earlier today. I really like the concept of the drawing on surface object. I haven't used that before, but I like the visual concept. Up next for me, list object. Many thanks
