make a divebombing enemy.

I'm trying to recreate the behaviour of these dive bombing hellicopters from cutmans stage in megaman 1.

Basically they fly straight then when they get within range they will dive up or down in an arc to hit you.

So far basically I've got a a bullet behvaiour on the hellicopter, and a big object matched to the hellicopters postion to reperesent it's detection radius, when that colides with the player it creates a target where the player was standing and the hellicopter rotates to target the radius. But I'm stuck on how to get it to do the actually kind of arcing motion when it gets to the target like they do in megaman.

Any suggestions?

Use pin behavior for the helicopter then temporary attached to player and also add rotary movement to simulate arc movement. That is one method, however you can use math expression using sin and cos operation.

You can check the distance(DiveBombing.X,DiveBombing.Y,MC.X,MC.Y) < a number, then Rotate toward MC position.

Something like this maybe?

With behavior method:

With expression (less object, less behavior)

The beahviour method you posted Alextro kinda had an idea I wanted and it looks like I'll be able to retrofit it into how I want the behviour, cheers.

Sure if that works best for you and fit the gameplay.
