Horizontal zigzag

Hello everybody ,

I'm developing a game that enemies must traverse a predefined path (horizontal zigzag crossing the screen), but I can not configure this movement.

Besides the movement, the enemy will appear in random locations.

Could someone please help me?

Use Sine behavior and Triangle option, or, a easiest way, use destination points with IDs.

When the enemy overlap the destination point with ID 0, and his ID is 0 too, make him follow the next destination point with ID 1, then, change the enemy ID for 1 and ahead.

To make your enemy go to the destination point is simple, and have many ways:

Setup your enemy to have the instance variable ID, the first valor is 0;

The same for the points, each point with a different and crescent ID number;

Everythick:

Enemy.posX < Destination_point.posX;

Enemy.ID = Destination_point.ID;

< Enemy.posX = Enemy.posX +1;

Enemy.posY < Destination_point.posY;

Enemy.ID = Destination_point.ID;

< Enemy.posY = Enemy.posY +1;

Enemy is overlapping Destination_point;

< Enemy.ID add +1;

Got it?

If you still needing help I'll do a sample for you.
