McTwist / BlocklandLua

Use Lua directly within Blockland.

BlocklandLua

Exposes LuaJIT to TorqueScript.

From the TorqueScript side, you can use luaEval to execute arbitrary Lua code (given as a string), luaExec to execute a file as Lua code, and luaCall to call global Lua functions by name.

luaEval("print(5)"); // -> 5
echo(luaEval("return 5")); // -> 5
luaExec("config/test.lua");
luaCall("foo", "bar", 1, 2, 3); // calls function foo

From the Lua side, there's a new global table called ts with the following keys:

• ts.eval(string code) - Run TorqueScript code in the global scope
• ts.func(string namespace, string function) - Get a Lua function which calls a TorqueScript function (mind the leading this argument)
• ts.obj(string name) or ts.obj(number id) - Get a handle to a TorqueScript object that can be passed as the this argument to a function resolved with ts.func. (there's also an alias of ts.obj called ts.grab).
• ts.global - Get/set keys of this table to work with global TorqueScript variables.

To work with object methods, first resolve the function (once) and later on call it with your object.

local getCount = ts.func("SimSet", "getCount")
local getObject = ts.func("SimSet", "getObject")

local ClientGroup = ts.obj "ClientGroup"

for i=0, getCount(ClientGroup)-1 do
  local client = ts.obj(getObject(ClientGroup, i))
  -- ...
end

There is also a global con table which provides simple access to TorqueScript functions in the global namespace. Just call functions on it.

con.getRandom(1, 6) ---> 4
con.getSubStr("hello", 0, 2) ---> "he"

FFI is available.
