Legacy GM Is it possible to save a path mid-way through? (Data Structure method)

[Dr_Nomz]

If I use a data structure (ds_map/list/grid) to save data, and an NPC is in the middle of a path, is it possible to save the position of the path the NPC is on, and then load it in WITH the NPC resuming it's path?

I'm using path_position and path_start btw.

Sure it is.

If your path is a resource, just save the index nd path position.

If your path is created dynamically, you can save all the points of the path then re build it later.

Okay but how would I write that in code?

Here's how I normally save data:

ds_grid[# enum.x, _row]=x;

The way I normally save variables is I take a ds_grid, use an enum to pull a value, and have it equal to whatever the current value is for that object. So like whatever the X position of the NPC is, it'll save that value.

But how about the path_position? Will it be able to distinguish different points of the path down to the decimal without error? Because path_position only goes from 0.0 to 0.5 to 1.0, and everything in between, which seems like it would cause issues.

This is how I normally load in data btw:

x=ds_grid[# enum.x, _row];

So the X value for the object would be equal to whatever the value is in the grid, for example.

Put all the path points into a ds_list. You can then turn that list into a string and put it in your grid or write it to a file. There are functions for all of this and should be relatively simple. so at least attempt it before I just write the code for you.
