How to Simulate distance travelled?

EireStudios

Hi Guys and Gals, I'm trying to simulate distance travelled in my game but I can't seem to get it to work.

I'm trying to just simply do,

when any

self.positionX = self.positionX+50

when self.positionY = self.positionY+50

when self.positionX = self.positionX-50

when self.positionY = self.positionY-50

change miles to miles+1

But this doesn't seem to work, I'm not looking for anything super advanced just something simple that works.

Any ideas guys? Thanks in advance

If the character were always moving, like in an endless runner you could just start a timer and say every X number of seconds add 1 to Miles.

If the character isn't always moving but you're using some sort of movement controls, like the keyboard. You could add to Miles whenever a movement key is pressed.

It's a top down boat game and I'm using a joystick to control the player, two good ideas mate but I'd like to do something along the lines of 50 pixels = 1 mile

Is the boat constantly moving forward? Would you want to check miles if they go left and right constantly, or is it for monitoring fuel etc?

Here is a little demo I put together that should work. It only keeps track if you move to the right by holding down the arrow key, but it should give you the info you need I hope.

Create attribute LastX, LastY, Miles, and Self.Distancefrom

Constrain Self.DistanceFrom to magnitude(SelfX-LastX, SelfY-LastY)

At the start
Change Last X to Self X.
Change Last Y to Self Y.

When attribute self.distancefrom is greater than 50
Change Miles to Miles +1
Change Last X to Self X.
Change Last Y to Self Y.

Think that should do it so it tracks in all directions, cant test right now though.

Yep, that is basically what the demo is I posted.

Nice. @Soulstealer Well there ya go, demo and all!

Thanks guys, I won't get a chance to test it until tomorrow but I think that's exactly what I'm looking for
