Hey folks! I made a new progress. I succeed to make you could change the grid target on the fly. Let say you target a grid and then you could damage the grid next to it. Such as linear targeting. It wasn't so hard. But deciding how the config should be is the hardest part. I didnt remember how many times I rewrote the script config so that I could make it more versatile. Anyway, here is the preview

Here how I decided to make the config. Of course I use TSBS as the base

Some explanation :

• :grid_save is where you could save the grid and you could restore the original grid target anytime
  
• :grid_add is to expand the grid. There're some methods you could use. Here I use :linear method to expand the grid. Put the directional button in []. The directional button is same as the numpad where 2 is same as down, 8 is up, 4 is left, and 6 is for right. Since the target is in troop grid, then the horizontal direction is reversed (4 = right, 6 = left).
  
• :grid_rem is to reduce the grid target. The new target grid will also target the previous target. So I substract the grid target with previous grid target just to make it wont get damage twice.
  
• :grid_setup is to setup how the animation / skill / etc acts. I haven't really thought anything. But will likely add more.
  

That's all for now.

And as for side note, I was listening to this music while doing some experiment and bug hunting
