Detailed Description

This area covers the special table functions. Many of Skylines lua commands can require special types other than the int,float etc.
These special types contain fields to easily pass related data. A common type is the vector3. This the has 3 feilds x,y,z which
can simplify code that is using vector positions.
EG.

pos.x = 10;
pos.y = 1;
pos.z = 0;

Using this special type we can define a variable to behave in this fashion. It can also contain optional args to initialise the new variable.
EG.

pos = newType.vec3();
--OR
pos = newType.vec3(10,1,10);

The returned table works in a similar way to defining a lua table with optional args. The lua equivalent is as follows:

function vec3(...)
    if(arg[1]==nil)then arg[1]=0;end
    if(arg[2]==nil)then arg[2]=0;end
    if(arg[3]==nil)then arg[3]=0;end
    return {x=arg[1],y=arg[2],z=arg[3]}
end

pos = vec3();

Use as newType.function()
The following code shows some of the the new types and how they can be used.

obj = 0;

-- Special table types
coord = newType.vec2(10,50);
posS = newType.vec3();
posE = newType.vec3();
col  = newType.color(1,0,0,1);

function onInit(objID)
    sky.lprint("LUA: Debub Draw 2 - Active!"); 
    obj = objID;
end

function onUpdate( timeDelta )
    posS = newType.vec3(entity.getPosition(obj));
    posE = newType.vec3(entity.getPosition(entity.getIDFromTag("t2")))
    draw.line(posS,posE,col);
end

Member Function Documentation

int newType::color

(

)

Returns a special table which is required when passing data between various commands.

Returns

table: Returns a special predefined table. Contains the fields {r,g,b,a}

The special tables can all be used to define and optionally initialise a vector type variable

Here is a Small Example of how to use this function:

myCol = newType.color(1,0,0,1);

int newType::vec2

(

)

Returns a special table which is required when passing data between various commands.

Returns

table: Returns a special predefined table. Contains the fields {x,y}

The special tables can all be used to define and optionally initialise a vector type variable

Here is a Small Example of how to use this function:

coord = newType.vec2(10,50);

int newType::vec3

(

)

Returns a special table which is required when passing data between various commands.

Returns

table: Returns a special predefined table. Contains the fields {x,y,z}

The special tables can all be used to define and optionally initialise a vector type variable

Here is a Small Example of how to use this function:

pos = newType.vec3(0,1,0);

int newType::vec4

(

)

Returns a special table which is required when passing data between various commands.

Returns

table: Returns a special predefined table. Contains the fields {w,x,y,z}

The special tables can all be used to define and optionally initialise a vector type variable

Here is a Small Example of how to use this function:

quat = newType.vec4();
