Editor UI

Finally returned to editor development.

Editor UI will be written by Lua scripts.

I started my UI from simple and usable source of Recast library,

For example, button usage:

if ( imguiButton("Start game") )

LoadLevel("super-duper mega Quake level.mdl")

this is button creation, displaying and logic in one place. After

years on Windows it was amazing!

I mapped API into Lua script language by luabind library, and

now UI script code looks like here:

if object_selected then

rollout( "Object", 0, 0, width, height )

show_object_properties()

if collapse("physics", true, true) then

show_physics_properties()

end

if collapse("visual", true, true) then

show_visual_properties()

end

if collapse("script", true, true) then

show_object_script()

end

end_rollout()

end
