Camera following the player

[Rabagast]

Hi!

I have a FSM on the camera with the action "Smooth Follow Action"
But I only want the camera to follow horizontal not vertical. When I jump, the camera is following the player vertical. Is is possible to freeze the Y-axis on the camera or something?

Did you try to just overwrite the Y Pos every Frame with Set Position XYZ just setting the Y Value?

I actually like the "Move Towards' action. I've had success just looping it into itself for a good camera follow.

redikann:

But how can I stop the Y-axis with "Move Towards action"?
Do I place it on the camera in the same state as "Smooth Follow action"?
I think I need a little bit more specific help.

[redikann]

It has an option to ignore vertical movement(y axis)

[redikann]

I use it to replace smooth follow. Just add a Finished event and loop it back into itself. But do not set the finish event for the Move towards action.

But now the camera is just moving towards the player until the player is disappearing. This is a 2D platform game.

[redikann]

Hehe well yes that's a problem there. You can set an offset so the camera is limited on any axis.

[redikann]

If you set a target game object then set a target position that position becomes an offset. I do not know the axis you are viewing from but I bet you can mess around and figure it out. The action will assume that Y is your up axis.

[Rabagast]

How can I set an object to an offset then?
The problem is now, when I'm walking to the left, the camera is ok, but when I turn to the right, the camera just fly through the player.

I apologize for leaving out something important to my set up. I parent my camera to an empty and I place that empty at the players origin. I do not parent the empty to the player but just place it at the same local space. You can move the camera wherever you want to in the scene because the logic will be run by the parent. It works great for my 3rd person cam but I haven't worked with it in 2d. Seems like it should work.

Ok! Just see if I have understood correctly. I make an Empty GameObject and place it as a child to the player. On the camera, I create a FSM with these actions:
-Move Towards
-Set Parent.

On Set Parent, I use the empty GameObject.
Am I in the right way?

But I know something is wrong here, because it doesn't work.

 :)Alright I am gonna walk you thru this again Sir.

1. Parent your camera to an empty gameobject.

2. Place your gameobject(camera Parent) at the origin of your player.
    Do not parent the gameobject to the player.

3. Place all playmaker logic for the camera movement on the parent gameobject.
    So place a "Move to" action on the gameobject(camera parent) that will
    move to the player.

You can see that I loop back into it with a finished event. I do not call the Finish event from a FSM action. It will automatically loop itself when ready ( granted you do not use an action that loops every frame). I find this to be a better solution than smooth follow for a 3rd person set up.
Also because your camera is parented to another object that moves it, in the editor you can move your camera around  until you find the correct viewing angle/distance and that should give you your camera offset. Move towards gives you the option to ignore vertical and the speed slider should be enough that your camera never lags if you need that.

Is it iTween Move To you mean I should use? And this I'm placing it in State 1?
And is it other Actions I need in state 1?
