You'll need the Unity browser plugin to try it out. (You can tell this by the z-position being.
It should be public so that we can call it from our colliders later.
So we're going to create them from our watermesh prefab which contains a Mesh Renderer and Mesh Filter. If nothing happens, download the GitHub extension for Visual Studio and try again. In his tutorial, Michael Hoffman demonstrated how we can model the surface of water with a row of springs. Setting Up Our Water Manager.
In his tutorial, Michael Hoffman demonstrated how we can model the surface of water with a row of springs.. We're going to render the top of our water using one of Unity's line renderers, and use so many nodes that it appears as a continuous wave. You can catch me on twitter, or at my developer blog where I write about game design. We'll need to remember that for later.
We only want one function in it: Using OnTriggerEnter2D(), we can specify what happens whenever a 2D Rigid Body enters our body of water. Stick them in the background. A sample of how to do some basic height map procedural generation with sprites. Because our particle system sends out a few sequential bursts of particles, so even though the first batch only last till Time.time + lifetime, our final bursts will still be around a little after that. Animating pixel art tiles isn't going to hurt performance. Also includes character sprites if provided for certain tilesets.
Looks like some good stuff. Remember we added that script to all our colliders before?

The first thing we're going to do is render our body of water with the LineRenderer component: What we've also done here is select our material, and set it to render above the water by choosing its position in the render queue. Generally, though, the Euler method will exponentially introduce kinetic energy from nowhere into your physics system, so don't use it for anything precise. Get access to over one million creative assets on Envato Elements. Well here's where you have to pass the right one. You may be looking at that code and thinking, "Why has he set the startSpeed twice? In this case, we just want the top-left, top-right, bottom-left, and bottom-right corners of our texture. You'll want to make a function called OnTriggerStay2D() which takes a parameter of Collider2D Hit.

The first variable is pretty simple: it contains all the vertices (or corners). We use Aesprite, and wasn't sure if animating water tiles would be … We're going to need objects to hold these meshes too. For instance, you could add the velocity to its current velocity, or you could use momentum instead of velocity and divide by your node's mass. Tilt the particle system to always point towards the center of your body of water—this way, the particles won't splash onto the land. If we changed the position of the first node straight off the bat, by the time we looked at the second node, the first node will have already moved, so that'll ruin all our calculations.

We'll start off by creating these: Now, Meshes store a bunch of variables. I think you could look at this tutorial and possibly make some adaptations for your game. You may have noticed that SetWidth() takes two parameters; these are the width at the start and the end of the line. First, we want to set the parameters of the splash to change with the velocity of the object. I've heard how powerful Unity is as an engine. We can calculate that like this: Now we set the velocity of the object that hit our water to that node's velocity, so that it gets dragged down by the object. Tip: For precise physics, we would use Verlet integration, but because we're adding damping, we can only use the Euler method, which is a lot quicker to calculate. Let’s get started! First, we need to make sure that the specified position is actually within the bounds of our water: And then we'll change xpos so it gives us the position relative to the start of the body of water: Next, we're going to find out which node it's touching. Therefore, we want to make an array that contains six integers, reflecting exactly that: This creates our quadrilateral. We will use a mixture of a line renderer, mesh renderers, triggers and particles to create our effect. Wrong! Now, we make our splash, and tell it to die a little after the particles are due to die. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. By using our Services or clicking I agree, you agree to our use of cookies.
Finally, you'll want to call SpawnWater() from somewhere. Now we have water that flows, and it shows. We want a game object that can hold all of this data, act as a manager, and spawn our body of water ingame to specification.
Now to actually set the values of our arrays. We publish 2D Top Down Tank Game Assets.
We'll start with the nodes: Here, we set all the y-positions to be at the top of the water, and then incrementally add all the nodes side by side. Is shadergraph an option for doing this to look nice/save performance in the long run?? (We'll also multiply all values by a spread constant). We set their position to be halfway between the nodes, set their size, and add a WaterDetector class to them. We set the mesh, and we set it to be the child of the water manager, to tidy things up. Why a little afterwards? We finish the loop by setting each node in our LineRenderer (Body) to their correct position. We'll use FixedUpdate() to modify them all incrementally. Here, we're making box colliders, giving them a name so they're a bit tidier in the scene, and making them each children of the water manager again. To do that, we're going to use arrays. You can change it … If nothing happens, download GitHub Desktop and try again.
First, the particle system we're going to use for our splashes: Next, the material we'll use for our line renderer (in case you want to reuse the script for acid, lava, chemicals, or anything else): Plus, the kind of mesh we're going to use for the main body of water: These are all going to be based on prefabs, which are all included in the source files.
