[SUPPORT] Advanced Turn Based Tile Toolkit

@Selentic: Ok, took me a bit, but I’ve got something to get you most of the way. The toolkit is built upon the notion that everything is truly turn based, and having multiple units act at the same time breaks this rule. I’m slowly trying to remove this limitation, but at the moment it takes a bit to work to achieve something like this.

The more specific reason for the problem you are seeing is that all units are referencing the same Path Index Array and spline in BP_GridManager and so they get stacked on top of each other. To fix this every unit need to have their own spline and path index array which is set up when they begin movement.

Ah so that’s where the problem was. I was confused because each unit seemed to already have their own spline set during pathfinding.

Unit_Parent already have their individual spline reference variables, just to cut down on casting and you can use this to set up a reference to a specific spline for this unit. For this I’ve created a new blueprint called BP_PathSpline that is a blank actor with a spline which I spawn at the start of unit movement and delete at the end of movement. There are probably more elegant ways to do this, but it is a quick and workable solution. Here is the part in the Event Graph of Unit Parent where I copy the spline held in BP_GridManager over to the new BP_PathSpline actor and also copies the Path Index Array from BP_GridManager over to a local array:

I tried this out with the same nodes you posted a screencap of above and it seemed to work fine. There might be quite a few hidden problems since I haven’t had time to test it properly amid all the Christmas cheer, but if you meet any other tricky obstacles just let me know. As mentioned I want to take the toolkit in this direction in the future so I’ll be interested in hearing of any problems you might encounter.

Excellent, thank you. I’ve got a couple other things I have to finish up before I focus on this part again, but those should be done shortly. Once I’m done with those I’ll let you know how this works.

After this you will need to replace all references in Unit_Parent to Path Index Array from BP_GridManager with the Local Path Index array. You will also want to destroy BP_PathSpline at the end of movement. Also, I’ve been a bit silly and set it up so that units are removed from the Unit Array in ATBTT_PlayerController instead of in the Event Graph of Unit_Parent which would make more sense (I’ll change this in the next update), so you will also need to add this after Begin Movement in the event graph of Unit Parent:

Oh man, it’s been a while since my unit_parent looked like that. I rewrote all that a while ago. That said, I spent more time than to admit when I started modifying things trying to find the part where it was writing the end position into the pawn array, though I thought it made more logical sense in the controller, but that might just be due to the context from the kind of game I’m working on. As long as they’re together though it should cut down on confusion for new people working with this.
