How do I do this :^)

I need help... I want to create following enemies, but I don't know how. All that I did is this:

Do the following:

Enemy: Has Line of Sight to Player:

• Enemy: Set angle to [angle(Enemy.X,Enemy.Y,Player.X,Player.Y)]
• Enemy: Move forward X pixels

(replace X by the amount of pixels you prefer. The higher, the faster the Enemy moves.)

Thanks, but I want to do that in a Platformer. How?

Here the example in platform.
