Swapping Scripts Based off of certain Conditions

If you plan on changing gravity, ALL of your code which considers orientation $$anonymous$$UST consider this change. That means your character controllers, mouse looks, absolutely everything that cares about "which way is up" needs to consider the project's gravity. The easiest way would involve letting any script who needs this information get it from Physics.gravity. Then "up" would be the inverse, or, -Physics.gravity.

If you want different objects to react to different gravities, that is a more difficult task. You will not be able to use Physics.gravity at all; ins$$anonymous$$d each object will respond to whatever gravity vector (and corresponding "up" vector) you choose, in whatever way you decide to choose.

This is not a simple task. It's certainly not impossible, and it sounds pretty interesting, but ALL of your code needs to respect the fact that their orientation can change.

Also, this implies not using "six different scripts" - which is a really bad idea anyway. Do you really want to change six different scripts each time you do anything? Bad bad bad. Again: Very very bad idea. ;)

If you absolutely insist, and to actually answer the question, "changing out" scripts is as simple as using RemoveComponent() and AddComponent().

$$anonymous$$y six controller scripts that are being swapped out each take a specific gravity axis into consideration and convert all controls over to that gravity axis. I am doing all of the calculations manually and coding the controllers with the correctly calculated vectors.

Even so, six scripts is not the best approach. Just replace any code that requires hard Cartesian axes to work relative to the current gravity using Cross Product in conjunction with Physics.gravity. Otherwise you'll wind up with six scripts for every object which considers orientation.

I feel like I may have accidentally derailed your question. Can you comment on what additional information you require?

$$anonymous$$y issue is that while adding the component for some reason I can not delete the olde one.

Earlier I said you need to use RemoveComponent() but I was mistaken. There is no such thing after all. (I can't remember the last time I wanted to remove a component.) The correct method is Destroy().

You must use an if-statement to check for the presence of each script variant, and remove it if found:

 VariantA variantA = GetComponent<VariantA>();
 if (variantA != null) Destroy( variantA );
 
 VariantB variantB = GetComponent<VariantB>();
 if (variantB != null) Destroy( variantB );
 
 // etc...

It would be best to put these checks in a method that attempts to remove every variant, call that method any time you're ready to change components, then add the variant you DO want with AddComponent() afterwards.
