Each spawn function has a specific interface for args as described below.

You can see exemple of use in Portal Gun mod.

When the defined square is loaded, if there is at least one container available on the square, it will add the item to it.

args is a table including
x: (float) coordinate Northing
y: (float) coordinate Easting
z: (float) coordinate Up
cItem: (string, FullType) item added to the first container found on the square.
rKey: (string) a unique key to identify your spawn args. this is required to not respawn the cItem on each load of the square.
hItem[optional]: (string, FullType) adds the full type of another item inside the cItem mod data for further use.
respawn: (boolean) if set to true, the cItem will respawn with the vanilla respawn rules defined in the sandbox options (except that the cell must be reloaded for that to work. if you do not know what that means, consider that after the vanilla timer has passed, your character must go 100 squares away from the target square and come back before the respawn occures)

1. When the defined square is loaded, a new IsoObject is added to the square. The ModData of that IsoObject include the information of a type of Item.
   
2. When the player right click on the square, the IsoObject is detected and the usual investigate button is replaced by a new one.
   
3. When that new button is activated, a research action occurs that adds the item to the player's inventory.

args is a table including
x: (float) coordinate Northing
y: (float) coordinate Easting
z: (float) coordinate Up
sItem: (string, FullType) item added to the mod data of the IsoObject on the square.
rKey: (string) a unique key to identify your spawn args. this is required to not respawn the IsoObject on each load of the square.
sprite[optional]: (string, SpriteName) adds a visible sprite to the IsoObject. -Does not work properly. The sprite is always loaded once. But most of the time it is not reloaded afterwards-

Quick question.

So is this a mod that gives to a interface to spawn any item or vehicle mod or from the base game?.

As i'm not too sure as i read over it as it says it spawns stuff but i'm not sure to what extent as having a mod spawn any and everything at any given time by few simple clicks would help me test items and vehicles in mods when adding new mods to see if they work as intended and conflict so far i'v been doing it the and slow way.

These spawn function are only for mods that want one item to always spawn at the same spot.
For item testing purpose, you should use the vanilla debug / admin "Item List" function.
For vehicle testing purpose, I do not know what you should use, but this mod wont help you at all.

Ah okey thanks yeah i use biki mod to spawn any and all vehicle related stuff and use the debug mod to spawn zombies and what not which is another mod but them two don't exactly bring up a interface panel to pick and spawn stuff like the vanilla debug you can activate before starting the game.

Which i can use and have before but would be nice to find the perfect mod that does that in a better way regardless thanks for the replay your a big help i'll keep looking for a mod that will aid me in spawning stuff in so i don't need to keep turning on and off the debug menu before i start the game :)
