Leadwerks 5 Scripting

[Josh]

I might have found a good library for the Lua binding that supports shared pointers:

Another possibility:
https://github.com/lubyk/dub

This one looks the most promising:

I added a massive amount of generated snippets based on the Leadwerks API. Video and more details here:

At this point it does not look like sol2 can do the bindings we want due to this issue:

I might have a solution!

I have this script working now with sol2:

print("Starting...")

local window = CreateWindow("My Game",0,0,1024,768)
local context = CreateContext(window,0)

local world = CreateWorld()

local model = CreateBox(world,1,1,1)
local camera = CreateCamera(world)

local v = Vec3(0,0,-5)
camera:SetPosition(v,false)

while true do
	
	local table = {}
	table.value = 1
	table.test = 3
	table.mything = "Hello how are you?"

	if window:KeyHit(KEY_ESCAPE) then break end

	if window:KeyHit(KEY_SPACE) then
		model = nil
	end
	
	if window:KeyHit(KEY_G) then
		collectgarbage()
	end

	world:Render(context)
end

Very nice. Is calling the garbage collector something we will have to do or is this handled internally?

Lua automatically calls the GC when enough memory is accrued, but you can also call it yourself whenever you want.

I’m at home right now and don’t have my computer here. I am very curious about something. Can someone please run this code in main.lua and telll me what it prints out?

v1 = Vec3(1,2,3)
v2 = Vec3(1,2,3)
v3 = v2

v3.x = 69

print(v1)
print(v2)
print(v3)

1.000000, 2.000000, 3.000000
69.000000, 2.000000, 3.000000
69.000000, 2.000000, 3.000000
 

If I use System:Print().

Thanks. That answers my question here:

This is shaping up really nicely. All your guys’ input is definitely appreciated.
