Welp, I realized I didn't quite explain what I was wanting to do correctly. My goal is to make a controllable row of destructable units, that stay in formation. You control the entire row, not the individual units. Kinda like a unit of fighters in Home World. Each fighter in the row can be destroyed individually, but the player controls the entire row.
The original idea I had was to use a container and turrets. You take a rectangle, attach 4 turrets to it in a row, and attach a soldier sprite to each turret. The problem is that if you pile everything into a container, and you destroy 1 turret, all turrets in the container get destroyed.
Honestly, I think the RTS template included with Construct was a better way to do this. But I don't know of a way to make the units move in a row instead of an unorganized mob. I thought the container/turret idea was a simpler way to try to do it, but it might not work.
Anyone have an idea on either option?
