Change Frames like Compass Sprite in 8dir

I was experimenting some mechanics, but this one made waste my time a lot, i tried with it some expressions like pixel distance and angle position, but it didn't work.

There a concept pic what im talking about:

There an unresolved .capx contains 8 frames for yellow head sprite, it contains no events because i removed useless events that never work:

Can anyone help me :o?

No idea of what you want, but I can tell you as far as angles go, 0 degrees would be frame 3, 45 degrees would be frame 2, 90 degrees would be frame 1, etc.

But that's not point, it's like Rotate X degrees toward this donut object but only is changing animation frames without rotating sprite.

I think this is what you are after?

Clever solution, sqiddster! You seemed to have some duplicate frames (maybe wrong version on dropbox?) so I pasted the correct ones in place according to Joannesalfa's drawings, but in the order to match C2's rotation, as you said.

Donut2.capx

Oops, you are right! My animations must have gotten messed up at the last minute! Ah well, you can see the logic, the important thing to appreciate is the angle() expression, which you will come to appreciate ;)

sqiddster and kittiewan, thank you for a great solution!

Apparently, i was figuring out to set animation instead of set frame, i got a type mismatch because it requires a string, not a expression like you did it.

I added an event like compare frame... but it didn't work :(

1-System| Every Tick:

--Sprite| Set Animation Frame to: floor((angle(sprite2.X,sprite2.Y,self.X,self.Y) + 180 + 22.5) / (360 / 8))

2-Sprite| Animation frame = 3:

--Sprite| Set animation to "Random Animation" (play from beggining)

Do you have ideas what i should to do?

Isn't that possible?

I'm not 100% sure what you're asking, but the following capx has changes to sqiddster's example to use animations instead of frames.

DonutAnimation.capx

Just concatenate the result of the expression onto a string to create the animation name string.

kittiewan omg... i knew i should to add & as string and concatenate.

Thank you a lot! :D

You're welcome, but I know you agree with me that sqiddster really deserves the credit for this one.

I know, this topic is old but is there any way, anyone to have any capx from this topic? I'm working on similar project and i'm looking for the code to help me. Thanks!
