How do I Tower Defense turret behaviour

How to create such a behaviour for the bullets of the tower so they chase the target of the tower and dont just travel in a straight line ( like for example in warcraft tds) ?

Add Turret behavior for the bullets and set the target as whatever the bullet should chase. If you don't know how to use the Turret behavior, there's a tutorial for it in the C2 documentary.

You could also do it by storing the target's UID into a variable within the bullet and then change the bullet's direction every tic, but that's a bit complex to make. I'd recommend going with the turret method.

The turret behaviour bullets travel in a straight line , i want them to be homing on the target.

Also tried to tweak the tower defense example that is provided with construct and the result was the all bullets were chasing a single enemy.

Homing bullet : every tick set angle toward target.x, target.y

Hope this helps
