This question has been asked many times... See this thread, it might help:

Screenshot of the scaling mode:

CigarOfSinatra : I mean your camera, see the pictures. The screen jumps around and has different positions in different layouts or stages of the game. (See screenshots below)

Also, what kind of scaling do you use for your project? Letterbox scaling? (see screenshot below)

Sure you set it up like this in C2?

Thought so, you are welcome!

Btw, I just wanted to post a problem with some lerping on rotation, when I took a look at the manual about your issue, and found anglelerp solving my problem

thren this is a great example about a platform-behavior-object following the player, but it might help:

heliogame

Take a look here:

That should help...

CigarOfSinatra what are your settings concerning scaling? There seems to be a problem with that, and also positioning.

Maybe this helps?

thren: you move the enemy by set position +1 px every tick. Of course it does not stop at the solid walls. You need to add some sort of behavior minding solids, like 8-dir movement. If you use path-finding (which I saw in your file), you need to register obstacles. But i would not recommend doing that, takes too long. Rather do the same (set direction towards player) but then move with 8-direction-movement towards the player. Then the enemy wont pass the walls.

Maybe you should check out lerp (ease out) and cosp (ease in and out) functions.

Also mind anglelerp for easing angle rotation.

See my example. It is really easey <img src="{SMILIES_PATH}/icon_e_wink.gif" alt=";)" title="Wink"> Hope it helps.

Radulepy : No, as I did in the first file, but then you always go forward, relative to the car (forward is not always up). You said that is not, what you wanted. So I swapped it to 8-dir movement, to have absolute directions (up always up).

@ekajuan

Also I would put the origin points not in the center, but where you want to have the joint between the body-parts. then it rotates around that. Otherwise you rotation, and set the position at the same time, cause the rotation center is off. That might cause the delay too.

Like a chain, the joints are not in the middle, but at each end of the nods (or always the one in front in your case), thus causing the chain effect. Better to use that as rotation center, I am quite sure!

Still you can try that, no matter how you model movement itself. Even a snail consists of backbone-joints with this mechanics, def. better, you simulate that right.

As far as Pinning goes, I meant: You can also pin position only, and detect/calculate the angle for the right behavior. Of course rope style etc. is not what you need. A snake has muscles in each part of its body, producing rather sine-waves when moving, than pulling itself along, like paralyzed. Sure that's not gonna work

But you got that part right, I'm just saying, you could rework the joint-points, anyhow you solve positioning and angles.

And yes, you do round: abs(round(Snake.Angle-Snake.old_angle)) and round(Snake.Angle) in your file...
