Distance Traveled and 8-Direction

I'd like to calculate the distance the player has traveled over the course of the game for a stat. The hero is controlled with the 8 direction behavior. How can I track the distance traveled if I know his speed every tick from 8 direction?

(Sorry, this is a "I'm in the 7th day of the game jam and I'm having trouble thinking about math properly" question.)

hmm.It seems that there is nothing for that right now.

What kind of game are you trying to make?

We may find an easier way if you tell

It's not that hard. I think. On top of my head:

Lets say your character moves with wasd keys. First you could setup a series of condition that detect these input.

Have the player object have lastx and last y instance variables.

Add a global variable named totaldistance.

Then, under every (direction input) condition call

totaldistance = totaldistance + distance(player.lastx, player.lasty,player.x,player.Y)

player.lastx = player.x

player.lasty = player.y

this means, every time you press w, a, s, d, system will check the distance of lastx, lasty position, add to totaldistance, and set new lastx and lasty positions. I hope I could explain it.

That seems right. Wertle,can you try that to see if it works?

Windwalker Actually i was thinking of something much simpler, which of course came to me after a good night's sleep after the jam was over

DistanceTraveled += Hero.8Direction.Speed*dt

It wasn't a critical stat or anything so no big deal, it was just driving me crazy that I couldn't think of it!
