Add FleeGoal

[lionaneesh]

A goal which can be configured to run away to a possible safepoint if X mobs attack. Also, later I want to add checks based on HP/Mana which can be configured via the Json.

Gooday, thanks for the contribution i will look into this sometime soon tomorrow. On the other hand i want to try out how it feels and probably going to help eliminate the warnings.

There's a way to get notified about upon a mob is died by the player. There's a decoupled messaging system setup where GoapGoals be able to communicate with each other without knowing each other.

I will definitely going to improve the PR that way.

In my humble opinion, making safeLocations as a LinkedList<Vector3> seems like an overkill.

In my humble opinion, a safe spot would be a location what the player was already stepped on in the recent past.

While the player is outside of combat, periodically X seconds or X milliseconds, a location can be marked as safe.

Upon entering the FleeGoal the goal execution would be really simple, from a Stack collection just pops safe locations until leaves combat.

There should be some guard clause that the safeLocations should contain about Y seconds worth of time in order to make sure that do not run out of safeLocations this can be checked in the CanRun().

Basically safeLocations.Count > 0

Essentially while the safeLocations has content we do not need to reach for the Navigation Component.

It should be a good idea to find out, after entering combat with a mob, how many seconds does it take till the enemy exit combat.

Hello, i've slightly refactored the code to be more simpler. It should give a better integration with the existing framework.

The biggest benefit probably is to see the path while in the FleeGoal. I left some TODOs in the code a few things needs to be figured out.

Currently when the SafeLocations is running out of saved elements, the player just keep moving forward until leaves combat.

However this can be dangerous 👀
