Hi guys, I am very new to Babylon but Im really liking it so far. I have been trying to make a camera follow a target between two players (on the x axis). To show both players on the screen at all times. Think Street fighter etc. Can anyone help me out as i am also very new to any kind of programming.

Hello and welcome to the Babylon community! I think @musk’s solution is a great starting point 🙂 It can be refined and customized a bit by calculating a “general” case, in which, given the two players’ positions, and a desired “margin” to the borders of the screen, you calculate the desired camera’s parameters - camera position, target, field of view (FOV), etc - to result in the proper viewing frustum: ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/8/6/866558c04b7d38193b0c26451904cf293f07bebb.png) The solution to this will involve, fortunately or unfortunately, maths 🙂 I recommend taking a look at Scratchapixel’s camera lessons as they give a nice overview of how a 3D camera works: [The Perspective and Orthographic Projection Matrix (Building a Basic Perspective Projection Matrix) (scratchapixel.com)](https://www.scratchapixel.com/lessons/3d-basic-rendering/perspective-and-orthographic-projection-matrix/building-basic-perspective-projection-matrix). Since Babylon.js already calculates the projection matrix for you, you just need to think about how the parameters will influence on the frustum, and plug them in Babylon. ---

Thanks for getting back so quickly! I’ll look into it and give it a go. This approach sounds similar to this unity tutorial video? [Camera - tracking two objects at once --- Unity Tutorial: short and quick - 125 seconds - YouTube](https://youtu.be/8wWhRG3FWIs) I also came across this unity video [MULTIPLE TARGET CAMERA in Unity - YouTube](https://youtu.be/aLpixrPvlB8) which uses bounds to centre the camera. Maybe this could be done in Babylon also? > **[Drawing Bounding Boxes | Babylon.js Documentation](https://doc.babylonjs.com/features/featuresDeepDive/mesh/displayBoundingBoxes)** > > Learn how to draw bounding boxes in Babylon.js. ---

That’s pretty much on spot! You can use the camera’s transformation matrix ( [Camera | Babylon.js Documentation (babylonjs.com)](https://doc.babylonjs.com/typedoc/classes/BABYLON.Camera#getTransformationMatrix)) to get from world to viewport coordinates, and the bounds approach is also a pretty good one (I like it even more than the first one to be honest) 😃
