How do make an sprite rotate 90 deggre in move.

How to move object like that ? im trying rotate but object cant stop rotating, or rotate instantly 90 degree. I need smooth rotate in move, from horizontal to vertical.

There are a few ways.

One is to give the the object the bullet behavior and add an event like this:

Every tick

--- sprite: rotate 10*dt degrees toward -90

Where 10 is the turning speed in degrees per second and -90 is the end angle.

Another way that is useful from a trigger is to add a instance variable "turningSpeed" to the sprite to tell how fast it turns.

Every tick

--- sprite: rotate clockwise self.turningSpeed*dt

start of layout

--- sprite: set turning speed to -90

--- wait 1.0 seconds

--- sprite: set turning speed to 0

--- sprite: set angle to -90

[quote:3rl6g7tj]One is to give the the object the bullet behavior and add an event like this:

Is the *dt necessary in events using a movement behavior, they already include it in the behavior movement according to Ashley's tutorial on *dt that says using it in behavior controlled movements could actually make the event framerate dependant again. Or am I misreading this...

It's needed in that case since the rotation is being done manually. "Rotate" is not part of the behavior.

Ahh ok thanks

Thanks ! Im gonna check it and post if its work for me ; )
