This example shows how to create a basic object using lua metatables :
MyObject = {} MyObject.__index = MyObject function MyObject.create(ref, pos, speed) -- object creation local newObj = {} -- our new object setmetatable(newObj, MyObject) -- set metatable newObj.object = getClone(ref) -- get a clone from the ref Maratis object newObj.speed = speed -- a local value setPosition(newObj.object, pos) return newObj end function MyObject:update() -- update function rotate(self.object, {0, 0, 1}, self.speed) -- rotate the object around the Z axis using the speed value end
It can then be used like this :
Ref = getObject("Ref") -- object to clone MyObj = MyObject.create(Ref, {0, 0, 0}, 1) -- scene update function onSceneUpdate() MyObj:update() end
