 # Animation basics
 
-## Explanation
 This C# Intermediate tutorial covers the basics of animation with Stride. All animations exist as animation clips assets in your project. From there on we can start, pause and fade animations by using Stride's animation component.

 # Async scripts
 
-## Explanation
-This C# Intermediate tutorial covers the usage of asynchronous scripts or 'async' scripts. Up until this point every tutorial has been using Sync scripts. That means that those scripts are executed right after each other. If one particular sync script would take 1 second to completion, our game would freeze that 1 second, untill the update loop is complete. All of the previously made Sync scripts can be made in to an Async script.

 # Collision triggers
 
-## Explanation
 This C# intermediate tutorial covers the use of collision triggers. It teaches about rigid bodies and how to set those up in the editor.
 
-Rigid bodies determine how entites in our scene behave on gravity, whether they collider with other objects or in the case of this tutorial": trigger collision events in our code. We do this by setting up a collider box in our scene and letting a sphere roll through this object. The events that are triggered are then processed by the script that we will make for it.

 ### Rigidbodies and collisions
 The code below looks for the rigidbody component that is attached to our entity. The rigidbody component contains all information we need for setting up triggers. The "IsTrigger" property determines that our collider doesn't stop other physics objects, but that it does trigger events in code (if they are set up at least).
 
-We spawn a sphere which also has a rigidbody. This sphere has a mass and is affected by gravity. The sphere will fall down and eventually roll through our collider box. In our update loop we check if there are collisions happening. If there are collisions, we get the colliding object and print out some text on screen. Once there sphere leaves the trigger box, our update loop sees that we no longer having collisions.

-The 3D to 2D or projecting happens for instance when you have 3d quest marker. When the target you need to travel to is somewhere in front of you in the word, then you want to draw a 2D quest marker on screen that gives you an indication of where in the 3D world that target is located.

-This script send out a raycast from the weapons barrel and sends it to an endpoint a little further. We check if hit something along the way. If we do, we calculate the distance between the weapon barrel and the hit point. We than scale a laser to that distance to visualize the actual raycast. Depending on the collision group and filters, some objects are ignored.
