Sounds great! How’s it going?
How to report your problem productively in the Unity3D forums:
This is the bare minimum of information to report:
- what you want
- what you tried
- what you expected to happen
- what actually happened, log output, variable values, and especially any errors you see - links to documentation you used to cross-check your work (CRITICAL!!!)
The general notes for what you are doing:
Referencing variables, fields, methods (anything non-static) in other script instances:
It isn’t always the best idea for everything to access everything else all over the place. For instance, it is BAD for the player to reach into an enemy and reduce his health.
Instead there should be a function you call on the enemy to reduce his health. All the same rules apply for the above steps: the function must be public AND you need a reference to the class instance.
That way the enemy (and only the enemy) has code to reduce his health and simultaneously do anything else, such as kill him or make him reel from the impact, and all that code is centralized in one place.
If you’re just seeing a NullReferenceException, you NEVER have to post for those because the answer is ALWAYS the same… ALWAYS!
