i cant figure out how my homeless enemy can sense the end of the platform.

I would go for invisible tiles/sprites as bumper and set them on the end of the enemies path and check of collision (tile/sprite vs enemy).

If it collide, let the enemy rest with a timeout and send him back afterwards.

do you use tilemaps for creating your maps?

 

if yes then use tile functions. 

 

If you have a tilemap and have the 2 tiles that are the ends of a platform you can create a function to do pretty much anything when the tile is touched.

 

Heres a post i made a while ago regarding the same thing:http://www.html5gamedevs.com/topic/3932-tile-callback-function-undefined/

the invisible tile will work for me coz my tiled map have too much different type of  platforms and somewhere i wont trigger this effect.

Wow, what a coincidence. This is the exact problem that I was working through today. Here's my solution: http://www.html5gamedevs.com/topic/7942-interesting-phenomenon-with-platformer-cliff-detection/

 

Basically I'm checking to the lower left of the enemy if he's going left and the lower right of the enemy if he's going right (as long as he is on the ground). If there's empty space there, I change the direction. This way I don't have to hardcode specific locations in the map or add invisible tiles.

There are pros and cons to both methods that you should consider. If at some point you want a character to, for instance, walk down some stairs, you will start to have problems with the detection method.
