Tiny Heist

Test when your player is moving not sure what method of input your using but you could create a variable and when you are moving for example keyboard w is down add sub event trigger once set value player moving to 1 then test if player moving is = to 1 on the enemy use path finding or whatever system you have in place then on w released same thing add sub event trigger once set player moving to 0

Eaxample

Add variable: player moving=0

Set enemy pathfinding diagnols off so guards only move up and down

W is down:

Trigger once while true: set player moving =1

W released:

Trigger once while true: set player moving =0

Player moving =1 : guard find path to

Trigger once wherever. X .y

Guard On path found:Move along path

Player moving =0 Guard pathfinding stop

Trigger once

Note you could also do this with out the variable by searching for path when w is down trigger once in sub bracket

Then on w release stop enemy path finding.

If you remove verticals from the path finding they will move in a grid like fashion under behaviors there is grid movement give the guards that behavior. There are some youtube videos on grid movement for construct 2 for enemy ai grid movement it depends how you want your enemies to move patrol a path or random.

Sorry the behaviors official name is tile movement.
