Chase the hero

[ER]

Hi,

How do I get the enemies "chase" after the hero ?

Right now I have one enemy on screen and moves until it hits a wall or
whatever
then randomly chooses a new direction to go. Which is ok but dull,
and robotic if you will.

I would like the enemies to chase after the hero but don't know how to
do that.

Enemy(1) is the array with current enemy.


Thanks.

You know the coordinates of the hero right?

So calculate a vector between the enemy and the hero. Have the enemy move along that vector.

Path determination and assignment is one of the more frustrating elements in game mechanics. Especially if you have a lot of obstacles on the map that the characters must take into consideration.

Apple has a relatively straight-forward guide to Pathfinding and Chasing here:
https://developer.apple.com/library/ios/documentation/General/Conceptual/GameplayKit_Guide/Pathfinding.html#//apple_ref/doc/uid/TP40015172-CH3-SW1

It’s aimed at iOS and Swift, but the logic still applies.

Not a direct answer, but it may get you looking into the correct direction.

HTH,
Tim

Ah I see. I'll take a look at it.

If it becomes to problematic I cloud just turn it in to a side
scroller a not have to worry much about that or
just make dumb enemies. HA!

Thanks.
