calculate the nearest CPU object ahead of the player along a pathfinding route

Hi,

I have a set of sprites that follow a pathfinding route, mimicking automatically going along a race track. One of these sprites is the Player (Yellow) while the others are all CPUs (Red).

I would like my game to work out which CPU is the next one in front of the player so that I can attach a sprite to it (For draft purposes). I have tried by picking the nearest CPU object but i'd like it to be clever enough to ignore any CPU objects which are behind the player (No matter which direction the sprites are travelling).

Any ideas?

The simplest method would be to use the Line Of Sight behavior in conjunction with pick closest.

Or trig it with pick closest to: player.x+cos(player.angle)*distance, player.y+sin(player.angle)*distance.

Just adding another alternative to Newt Ideas for variation

it could be to do a (Ranking System) you have a really nice example from R0J0hound on this thread:

https://www.construct.net/wf/forum/construct-2/beginners-questions-19/how-do-i-make-a-positioning-sy-87052

-Put all the (CPUs(Red) & the Player) in a Family

-Create an (Instance Variable: Ranking) and use the system Ranking from the Link

Now whenever you need to Pick who is in front of the Player then just compare the Variable Ranking

Example:

Pick Family: Where >>>>>>Ranking) = (Player.Ranking-1) >>>>>> Do your Staf

Thanks both. I got it working with the first answer but I'll play with the second as this will also help with all the positions :)
