Here's a quick workflow function for offsetting a character from their current position as that is what you appear to be asking for...
Add the function below into the script section of the editor as a
definition type script...
function offsetChar(char, x, y)
char = Characters[char] -- store the characters table in the char variable
char.Destination = { x = char.Position.x + x, y = char.Position.y + y } -- update destination
end
To use the function wherever you need it, you can create an
execute a script action part & then you would add some code along the lines of this into it...
offsetChar("Tom", 300, 200)
Quick note: if you use negative numbers then it will subtract from current position instead of adding. Example: -300
Anyway, just in case you want to know how to send a character to absolute coordinates, then this is how you would go about it...
game.CurrentCharacter.Destination = { x = 300, y = 200 } -- update playable character destination
or...
Characters["Tom"].Destination = { x = 300, y = 200 } -- update Tom's destination
