make enemy follow footsteps

[blurymind]

Hi,
I am trying to make some enemy AI logic in fusion.
So far so good, but got stuck on the part where the enemy is following the player .

Its a stealth game, where running on top of a certain type of terrain leaves footsteps.
The footsteps are one object being created every half a second while the player is running. Each instance plays slowly a decay animation and when that animation is over the footstep object gets destroyed.

So Right now what I am trying to achieve is get my enemy to pick the oldest instance of a footstep object and move towards it (bouncing ball movement+aim at). When coliding with it, move towards the next footstep in line and so on.


How do I get fusion to pick one object out of an instance by how long it has existed on the frame? Or by how close it is to the enemy.

Basically I want the enemy to follow the player's crumbs.

Is there an example out there I could look at?

Thanks in advance

I have an open source example on my website. The player leaves dots and the enemy follows that, thus tracking the player. "Node Example".

Hi Marv,
I will have a look on that thank you

Hi Marv, the example is really nice, but it is very specific.
In my case the player is creating a different number of footsteps depending on the environment and I dont want the enemy to destroy the footsteps when coliding with them, so as to be possible for other enemies to pick them up.

I think in this case if the nodes were not destroyed the enemy would stop, as the enemy is programmed to follow the oldest node.

so maybe using a variable instead of the oldest node? And on each collision the variable gets updated?

Try that and see if it works. To tell you the truth I can't get my head around that and if it works throw me an example.

Thanks,
Marv

Here's a solution, although it lacks a distance check: https://www.dropbox.com/s/zb9pz2m97g...step2.mfa?dl=0

this is a great example casleziro
It solves things for me. I will try to use it in my game
