Roatating object

[Tiger]

Im making a bullet hell shooter, and want to have a special type of bullet rotate around the player getting ever so slowly closer with each orbit. How can i do that?

Do you want it so that it gradually moves in on the player, or do you want it so that it specifically only moves in when it's completed an orbit?

I want it to gradually move in.

Trigonometry is the key word here. You want to position the object based on your players location so that its offset at polar coordinates, lowering the distances to make it get closer.

Generally these are given by equations like:


X Position of "Bullet" = X Position of "Player" + Cos(BulletAngle) * Distance
Y Position of "Bullet" = Y Position of "Player" - Sin(BulletAngle) * Distance


An easier way to do a similar effect if thats a bit much, would be a cheap workaround- give your bullet a "ball movement" and then set its directions like this:

Always - Make Bullet look in direction of "Player"
Always - Set Direction of Bullet to (Direction of Bullet + 7)

And then to make it move in closer, just keep decreasing "Distance" by whatever, and to control the speed at which it orbits the player, just keep adding some sort of "Speed" value to "BulletAngle"
