"With" function problems with x&y coordinates

[Anthony Summers]

xx = self.x;
yy= self.y;
player = playerTactical.selected);
with(player){
path = path_add();
path_add_point(path, playerTactical.selected.x, playerTactical.selected.y, 100);
show_message(string(playerTactical.selected.x) + ": " + string(xx));
path_add_point(path, xx, yy, 100);
path_start(path, 16, path_action_stop, 0);
}

This code is in the event of the left click for an object. When you click the object it makes a player walk to it. However I'm having an issue. As shown with my show_message statement both of my x values reveal to be the same. The player however is much farther both y and x.

I made xx equal the objects x position before we went into the with statement as I believed that would mess it up. However it still shows the object and the player having the same x position.

What is happening?

solved, i guessed. xx and yy needed to be var xx and var yy. Can someone explain this?

Everything inside of "with {}" runs code in the other object. The other object does not have access to the xx and yy variables. Don't forget your indentation (press TAB on lines inside of brackets), it makes problems like this much more easy to recognize.

var gives the other object access to the variable when using with{}, that's just how it works. https://docs.yoyogames.com/source/dadiospice/002_reference/001_gml language overview/variables/local variables.html

You have to use other.xx and other.yy

You could also just use other.x and other.y instead of copying tha variable

The "other" keywork is used to access the instance that called the with statement
