-====== Tutorial de Desplazamiento ======
-===== Sumario =====
-See previous [[main#Basic|basic tutorials]] for more info about basic [[object|object creation]], [[clock|clock handling]], [[frame|frames hierarchy]], [[anim|animations]], [[viewport|cameras & viewports]], [[sound|sounds & musics]], [[FX|FXs]] and [[physics]].
-This tutorial shows how to display a [[wp>Parallax_scrolling|parallax scrolling]].
-As you can see, there's no special code for the [[wp>Parallax_scrolling|parallax scrolling]] itself.\\
-Actually, orx's default 2D render plugin will take care of this for you, depending on how you set the objects' attributes in the config file.
-By default, in this tutorial, the attribute ''AutoScroll'' is set to 'both'.\\
-This means a [[wp>Parallax_scrolling|parallax scrolling]] will happen on both X and Y axis when the camera moves.\\
-You can try to set this value to x, y or even to remove it.
-Along the ''AutoScroll'' attribute, you can find the ''DepthScale'' one.\\
-This attribute is used to automatically adjust the objects' scale depending on how far they are from the camera.\\
-The smaller the camera frustum is, the faster this autoscale will apply.\\
-You can try to play with object positionning and camera near & far planes to achieve the desired scrolling and depth scale rates you want.
-You can change the scrolling speed (ie. the camera move speed) in the config file. As usual, you can modify its value in real time and ask for a config history reload.
-As you can see, our update code simply moves the camera in the 3D space.\\
-Pressing arrows will move it along X and Y axis, and pressing control & alt keys will move it along the Z one.\\
-As told before, all the [[wp>Parallax_scrolling|parallax scrolling]] will happen because objects have been flagged appropriately.\\
-Your code merely needs to move your camera in your scenery, without having to bother about any scrolling effect.\\
-This gives you a full control about how many scrolling planes you want, and which objects should be affected by it.\\
-The last point concerns the sky.\\
-As seen in the [[frame|frame tutorial]], we set the sky object's frame as a child of the camera.\\
-This means the position set for the sky object in the config file will always be relative to the camera one.\\
-In other words, the sky will always follow the camera.\\
-As we put it, by default, at a depth of 1000 (ie. the same value as the camera far frustum plane), it'll stay in the background.
