This project is a big sand box of tools & test, my initial goal was to create a mario galaxy like.
This readme will show you the iteration I have done to complete this task.
The direction of the gravity is relative to the environement. I Need to quickly setup in wich direction the gravity is facing for each environement. To Have a generic approach, my idea is to have the direction of gravity facing the closest object in the level Design.
First, I am calculating closest points to a cylinder primitive:
Here you see gravity direction can be facing:
- the trunk of the cylinder,
- the extremity of the disk top or bottom
- inside the disk top or bottom
Then I need to apply gravity force from multiple target. I call them Attractors
For design purpose, the closest Attractors always apply the same force X.
Then the farest other Attractors will apply there own force, divided by a distance ratio.
For going further, I need to be able to use only certain part of the Attractors to apply the gravity. Therefore I have done a custom editor to be able to manipulate these option directly from editor. I call these option GravityOverride
You see bellow that I can choose to not apply gravity when the player is over a certain part of the cylinder:
I have worked hard to have as many Attractors as possible, and for each of them, as many GravityOverride as I can.
GravityOverrides are separate from there non-GravityOverride friends, to save performance if we don't want them.
These Attractors can be Moved, Rotated and Scaled like a normal gameObject in editor !
Here the final list of all current Attractors:
I have created a line editor to have custom gravity setup for some level. This editor is of course, compatible with both GravityOverride, and Line Edition
And now the same for muliple lines:
To optimize calculation, I need to be able to organize the level design into chunk, and calculate only attractors inside this chunk.
I have create Special Zone, which contain a list of Attractors:
I can explicitly set a Zone inclusive, or exclusive from others:
Here a list of zone shape I can choose:
