DEVIGN : Construct2 query : Having a uniform Walk Cycle

I am not able to find a way how to have a uniform walk cycle.Seems like the code below works everywhere except on Solid objects.

What mistake I am doing ?

DEVIGN : Construct2 query : Assign a path to AI creature

I have been working on Construct2 recently.Want to know how to achieve the following:

(a) Player to move in any direction ( 8-direction movement)

(b) Bad guy (AI) to follow only the path defined say on the bridges and the trees

The images below might explain my query clearly

Hence, the player stays safe as long as he is away from the tree and the bridges

more queries ?
