Sorry this is so long and may seem like rambling. I've been working on so many things relating to Leadwerks in game and tool-wise that this doesn't even begin to cover it.
When I started my Halloween contest entry, I had a very simple idea: You have arrived in area/town/location x, you need to get out. As I started to fill in the blanks I realized that this project would never be done before Halloween arrived. I started using Articy:Draft in detail to bring all the overflowing ideas back to manageable levels.
Now what I have most of the plot fleshed out I had to start on something that few of us bother worry/care about: Standards. Most games, at least Source and Unreal, have standard practice dimensions for most things. Doors, windows, walls. floors. Before making one single asset I will need to know what should be the same everywhere and what problems I will run into.
What do we know about Leadwerks?
Leadwerks now uses a cm grid that goes by powers of 2 so you will need to stop thinking in 10's
*these are measure to the ALMOST literal limit. so anything larger is safe
NavMesh Generation
*NOTE* There are many edge cases/exceptions to some of these measurements
Shortest navigable covered area = 213cm
Smallest navigable squared area = 206cm^2 x,z * edge-case if the centrer of the nav area is (0,0,0) you can get it even smaller [its a bug]
highest navigable step = 50cm y * there are some edge cases
narrowest navigable corridor = 116cm
*the character controller is prone to even the slightest floating point error
*so some of the measurements are adjusted to fall safely short of some
FPS Limits:
Shortest navigable covered area: 184cm * no jumping room
Narrowest corridor = 76cm *lots of Jittering, if you make it 1-6cm smaller you will begin to noclip and the fps player will die
step height = 57cm
Slope = 45degrees
While Crouching toggled
shortest covered area = 120cm y
Narrowest corridor =80cm width[adjusted ]*hella floating point issues
step height = 8 cm *SERIOUSLY!?
slope angle = 45degrees *FLOATING POINT ISSUES AHOY. You will have issues the further away from origin (0,0,0) you are
*note if you start from flat ground while crouching and go up a slope while crouching , you will slide back once you stop going forward [bug]
Now that we have learned some things about Leadwerks what do we do with it? Interpret, Extrapolate, Interpolate , and Implement!
I think we have all seen the guidelines that recommend a 256x256cm wall is a perfect fit. Its completely fine if your game doesn't have any jumping in it or it is severely restricted. I know that the player will be climbing over things indoors so 256cm will simply not be enough. The solution I have come up with is 320cm tall walls, with 8cm walls and 8cm ceilings. This gives us a 384cm tall block that fits perfectly in the 128cm^3 grid spacing. Now with a wall that high you can I have set the doors to be 128cm wide and 256cm tall. Because we know the problem Leadwerks has with crouching and step heights we know we need to come up with a solution be it putting ramps (visible or not) in the door or adjust the fps controller by code to check for ledges while crouched.
Keeping the default fpsplayer height of 1.8meters (5foot, 9inches) I have set the counter and tables to be 80cm tall. Windows are 80cm from the floor and have a height of 176cm. The heigt allows you to easily jump out the window while crouched without encountering weird physics behaviour.
With these standards set I can make assets that can be swapped in and out with very little issues.
Nice pretty tabular format
