3D physics is now built in G develop the physics engine being used is jolt an open source 3D physics engine that's already being used in a number of AAA games in this video we're going to go over a couple of quick examples and show you how it works and what it's actually going to look like in a game so I have this 3D box here and it doesn't currently have any behaviors so I'm going to add the 3D physics behavior named 3D physics engine and the 3D physics engine is basically the same as the 2D one where you select the type of object be it Dynamic static or kinematic select the shape of the object so sphere box capsule or cylinder capsule and cylinder being the most common ones for characters in a game and then tweak the settings of the object picking between the density gravity scale and things like that so all you need to do is add the behavior to the object and press apply and now this box is a 3D physics object I've already given the ground the behavior and made it a static object and I also have this box object that I'm using as a camera so I can control the camera in the scene so now if I preview the game I have it set up so that the boxes will continually fall over and over and over again and we can see the physics in action you can see the boxes bouncing off of each other and basically just being 3D boxes so the 3D physics Behavior works on 3D boxes as well as 3D models so if I grab one from the asset store and add it to the project I can drag it into the scene and just like before I'll give it the Behavior Keep It set as Dynamic and change its shape to a sphere because it's a ball and we can see that because it's so big the boxes didn't really push it much so if I go to the object go to the behavior and change its density down to something really small and then preview the game it gets knocked right off the map so you can play with the settings to make objects react and behave differently but then you can also get more into game related mechanics by using the different actions and conditions that come with the behavior and by trying out a bunch of the other 3D behaviors to create more of a game and less of a physics test so in this game example for example it's using the third person camera extension along with the 3D platformer character extension to work with the 3D physics engine to make a game so for example these boxes are down here and I can go push them I can go push them and knock them off the level the 3D physics behavior is relatively new so some things are bound to change in the near future but but you can check out this game example and how it works in the engine in the create tab when you create a new game just search for 3D a number of the other 3D examples have also been updated with the 3D physics Behavior as well as the physics character 3D Behavior so you can try those out in the engine right now but if you want to learn more about how to use gdevelop then check out this playlist [Music]
