[FEATURE REQUEST] Isometric game character movement.

Well I finally made a tutorial about this.

I agree with Katala's idea of having a top view layout in the back.

For pathfinding and other motion in iso the simple thing is to do it in top view and then position some isometric objects from the top view positions to isometric positions.

The math is simple:

IsoX = x-y

IsoY = 320+(x+y)/2

Example:

I left the top view stuff visible but in practice you would make it completely invisible. The advantage of doing it that way is all behaviors can now work as an isometric motion.

The animation aspect is basically the same as changing animations in 8-direction.

To me z-sorting is the hardest aspect of isometric. In the capx I sorted by Y which doesn't sort right in some cases.

Yep, it doubles the number of objects, but it simplifies things enough to make it well worth it.

I was hoping to use tilemaps for just the 2d part, but I found that containers work better, and the two don't work well together.

Although it might be worth it if you used it for just non movables, borders, buildings, etc.

Heh that is much simpler than what I have been using. What would you use from iso to top view. Like mouse click for example.

Here's the reverse.

x = iy-320+ix/2

y = iy-320-ix/2

With mouse I got it to work like this.

mouse.Y-(LayoutWidth/2)+(layoutwidth/2+mouse.X)/2

mouse.Y+(LayoutWidth/2)-(layoutwidth/2+mouse.X/2

Too much MATH is not good for a graphic designer's stomach ... ugh

I took one look at this - and I almost puked.

So like I said before, if someone from Scirra (or anyone else for that matter) is willing to make full behaviors, events, etc. for this and have it in the Asset Store, that would be great.

What else would you need that is not provided here? https://www.scirra.com/tutorials/1169/basic-isometric-projection

I think Rojo and I already provided everything you need.

This might seem like very complicated but, isn't so much in the end. And you don't have to bother with it anymore. It just shows some principles if someone is interested.

Im working on more of a complete game now.

I'll try to have it out next week.
