I am trying to place a button onto a canvas background using C script. I want the button specific to the canvas i. My C script is below. I have attached it to an empty game object. When I run the game, the Heirarchy panel of Unity shows that the canvas and button are created OK, and that the button is a child of the canvas.
The canvas appears in game view at the right size x The button is definitely present ; clicking on its name the Heirarchy panel shows me a location and size in the scene view that are exactly as specified in my C script. But nothing happens when I click the region in game view where the button is supposedly present.
Unity's Inspector panel shows that a "Button Script " has been attached to my button object, with Rect Transform parameters as specified in my C code. I tried messing with the colors, but still no button. The "On Click " window contains nothing except the message "List is Empty". As you have already fixed the positioning problem, I'll only address the second question about the button, which appears to not function at all.
First of all, I really recommend to set this up via the inspector, it's a pain to set it up manually in a script, but here we go:. In CreateButton Delete the following line as you already have a canvas.
Adding a Behaviour that inherits from BaseInputModule will automatically add an EventSystem component, if it doesn't exist yet. Add the following, it's probably the best if you do so before you start to build up the canvas. Last but not least, you also need a GraphicRaycaster component. Add this line when you added your canvas component. Now you're be ready to go - so far. But i still really, really recommend to set this up via the inspector. Instead of. The Canvas co-ordinate system is a bit different.
The origin is at the centre of the canvas. And the size of the canvas gets divided evenly with respect to the origin. So in your case the canvas width isso the left extreme co-ordinate becomes Your button position is which exceeds hence it doesn't lie inside the canvas. OK, here is the exact code I am using, including stuff that might not be relevant to the problem. I tested it first and then just pasted it all straight in. For me, it creates a canvas with text, and a button right in the middle.
But the button does not function. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered. Why does a UI button that is child to a canvas not appear in game view?Creating the visual elements of a game is only half of the work. Once you have your monsters in place, and you have primed all your catapults to fire, a colossal battle may appear underwhelming when the greatest of explosions fail to produce even the tiniest whisper.
But when you add sounds to your game — even terrible ones at that — you may be shocked to discover the depth that they provide. Throw in some awesome sounds and you may discover an entirely new game.
This tutorial will show you how to add sounds to the game Barn Blastervia the Unity editor and added code. If you are new to Unity or need a refresher on the basic concepts, check out our Introduction to Unity tutorial.
You can download the materials for the project using the Download Materials button at the top or bottom of this tutorial. Open the project in Unity minimum version When you press the Spacebar key, a farm animal launches into the air. The goal of the game is to land the animal in the barn without it getting hit by a tractor.
The game is set up to launch a random animal: a cow, pig or sheep. Each one will play a different sound, so your first task is add the sound effect of the animal being launched. The project has already been set up with prefabs for each animal. The first thing this prefab needs is an AudioSource component to play sound.
Then, select the Audio Source option that appears. The cow prefab can now play audio, but it needs an AudioClip to play. Currently, the AudioClip on the component you added is empty. You may be wondering: what exactly is an AudioSource? How does it differ from an AudioClip? An AudioSource is what will actually play the sound in 2D or 3D space. You can set an AudioSource to play sound in 2D spacewhich means it will play at a consistent volume regardless of the distance from the AudioListener.
One important thing to note is that the AudioSource is a component. The AudioClip is a variable that can be set on the AudioSource i. You can attach components through the Unity editor and through code, though this tutorial only uses the editor. A key part of playing sounds is setting up triggers for AudioSources to play.Audio is quite an interesting concept to cover, not only in game design but when studying its nature in general.
The way it's perceived depends on a lot of factors, which have to be taken into account when you're trying to control or use it. Perception of audio generally involves the position of the source and how fast it's moving if it's moving at all If you've studied Physics, you may be familiar with the Doppler Effect. In Unity, the positioning of a source of audio is important to characterize its source.
For example, we need to make sure that a gameObject playing the sound of a waterfall matches with an actual waterfall gameObject, and that the player's perception of that sound feels real. Getting louder as the player gets closer, making sure the audio panning varies as the relative position of the waterfall changes with respect to the player, and so on. This is a component that's automatically attached to the main camera every time you create a scene.
It doesn't have any properties, since its only job is to act as the point of perception. Leaving the Audio Listener as it is, is recommended. This is the component that's actually responsible for playing the sound. In common development practice, it's generally a good idea to make an empty gameObject to act as the Audio Source and make it a child when you're dealing with large, complex structures, so you have a clear idea of where the Audio Source is.
The Audio Source component has quite a few properties which we can tinker around with. This includes its pitchpanningspatial blending We'll get to that laterand if you open the 3D Sound Settingsyou will find options for adding Doppler Effects and volume rolloffs.
What interests us the most here is the AudioClip slot, however. That's where the sound effect to be played goes. Unity supports quite a few common sound formats, including. Until sound-supportive documents are supported, we'll have to create our own sound effects. We have made a package of a pair of small sound effects, which you can download from here.
Let's import these sound effects into our project by creating a new folder for sound effects and adding the sounds to it. Now, since the main camera already has an Audio Listenerall we have to do is add Audio Sources to our relevant gameObjects. First off, we'll have a sound effect that plays when our character fires a fireball. For that, we'll simply attach an Audio Source to our character's shooter gameObject. In the AudioClip slot, drag in the sound effect you want to use. If you downloaded the soundpack, drag in fire1.
Now, untick the Play on Awake checkbox. This makes sure that this sound doesn't play as soon as the gameObject awakes, which in our case is as soon as the game starts. In the tutorial Prefab Instantiation and making them movewe created a class Shooter which was instantiating a new fireball every time Spacebar was hit, let's add sound when a new fireball is fired. Besides the declaration of the AudioSource variable initially, the magic happens when we call, source.
This line of code makes the referenced AudioSource play the AudioClip that's loaded into its slot.Hello, I'm a student game dev and I need help with the hover features in one of my games. I've tried to implement some makeshift keyboard controls using code I understand GetKey KeyCode.
GetKeyDown KeyCode. Because I only have two possible buttons Play game and quit game I've decided to use this code. This code works, the only problem is there is no effects for the player to tell what button they have selected. After selecting the index of the button, find SetActive true on the hightlight-gameObject.
SetActive false on all the other objects. Create a monobhehavior script, and make it inherit not only from Monobehavior, but also from IpointerEnterhandler. This will force you to specify a function void OnPointerEnter. It will be automatically called by unity whenever a UI element a gameObject with this script and with an image gets a cursor hover over it.
Use this function to perform any highlighting to the button its attached to. Recall, you can get refrence tot he gameObject from the script its attached to by this. Recall that UI elements require you to add using UnityEngine.

I use image effects to create an early morning sunrise look. These are before and after screenshots of a scene with no image effects, and then the same scene with several image effects added. Click the image to see the before and after at full size. Unity 5 introduced the Standard shader, which is now the default shader used for materials and 3D objects.
When you import a 3D model or when you create one of the built in primitives like a cube or a sphere Unity will apply a material that uses the Standard shader. HDR stands for high dynamic range, which means that your camera in Unity will be capable of capturing luminance values that are beyond the range of your computer screen.
Rendering paths are beyond the scope of this post, but the Unity documentation provides some good explanations. This will bring up the Import dialog box, and you can simply click the Import button. Image effects are scripts that can be added to a camera object in Unity from the Scripts folder mentioned in the previous paragraph. When the game runs, the camera renders the scene, and then each image effect manipulates the rendered 2D image in some way. Many of the effects that can be applied are the same types of 2D manipulations that could be done in an image editing program like Photoshop.
To add an image effect, simply select the Camera in the Hierarchy window, and then drag one of the scripts over to the Inspector window.
One fun effect you can try is the Vortex effect. This will twirl and warp the image, and the Inspector has several adjustments that allow you to change the parameters of the effect. This scene looks decent, but we can make it and just about any scene look better by carefully applying some image effects.
On a camera in Unity, each image effect will be applied in sequence from top to bottom. Click each image below to see a larger and more detailed version that includes the Inspector settings for this particular scene. The default Bloom image effect will take the high luminance pixels from the HDR camera and effectively blur them outwards.
Computer screens have a limited range of brightness values, so this helps create the illusion of overly bright parts of the image without clipping the values and blowing out the colors. Tonemapping does this automagically and allows you to safely and predictably apply more effects. Screen space ambient obscurance SSAO is an image effect that will apply small shadows in the crevices of geometry and underneath objects.
If you look at this image full-size, you can see that there are now subtle shadows around the objects and below them to help visually fix them to the ground plane. Ambient occlusion is a naturally occurring phenomena you can see it best in a sunlit room where two walls meet at 90 degreesand screen space ambient obscurance is the fastest way to create this effect. The Noise and Grain image effect adds a small amount of animated random static to the image.
Rather, adding some noise and grain to the image will help smooth out any color-banding that may appear in subtle gradations from one color to another. Noise and grain helps to fill in some of the gaps in color.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I have a 3d-object cubewhich I want to use as a button. I've written the code in order to detect, if the cube was pressed but it doesn't look like it was pressed, since it lacks the "clicking animation". How can I create a clicking animation on my 3d-object? A good idea is to play an aninimation which skrinks the cube a bit and releases it immediately afterwards. The handler code you want to execute on a click might block the game loop, e.
Then it might be useful to load the level aysnchronously to be able to see the animation. Or you execute the handler code after the animation.

Or you play the scale down animation on the press event and the scale up animation on the release event. Technically you can use the build in animation editor, the Update method, start a coroutine or use the assets iTween or HOTween. Unity makes it easier now to do this using Unity Canvas UI. Instead of real 3d buttons, you could place a canvas UI in world space at the location where you want the buttons.
Now, you have out of the box several clicking effects.Button Animation (Using Animator) - Unity 3D[Tutorial][C#]
The default it color tint, but you can choose sprite swap, or animation. If you do want animation, when you select button animation it will create an animator for you. Click on your UI button Game Object in the scene hierarchy and open the animation window.
Now when you click on the button it will animate a cool scale down for you. Sorry, I know that is a lot of information dumped!
But you will find it pretty great once you start working with it in world space. On mouse up, rescale or recolor it. You can implement your button using new Event system of unity.
