![enter image description here][1]please I need some help, this should apparently be something very simple and basic to do, but maybe I'm missing something.
I'm quite newbie to Unity3d, I had no much problem with creating a somewhat flashy 2.D scene (I mean 2D with different layers in Z level), scripts, etc. But I'm having trouble to create a "UI Slider" object: when I create it, it just shows nothing on screen. How can I make it visible? I just need to create a very simple, plain slider whose value can be controlled at runtime by means of a script.
thanks.
Well.. since you give nothing to go on, I suggest that you take a look at a tutorial for the UI:
https://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/using-the-ui-tools
If you have troubles after this tutorial, come back with an example of your problem to make people more willing to sacrifice their time in helping you.
Hope this is somewhat useful
Take a look at the Unity3D docs here.
http://docs.unity3d.com/Manual/script-Slider.html
It should have what you are looking for.

I got an assignment to create a website that looks like this. I have all of the images but I am stuck.
I am a pretty rusty coder.
Some of the things I can't seem to get are.
Image cropping: how do I make it so that it shows part of an image.
Moving objects around: do I use float or grid or flex?
Overall just feeling overwhelmed. Help?
Good test project I would recommend you get you requirements on this down first, like ACVM stated then you have to also consider your strength on this requirement the break down to sprints and chunks/milestones before you start coding.
Language I would recommend for easy development:
php - to handle mailing and contact us
html5 and css5 - creating the layout/design (preferably bootstrap check wrapbootstrap.com and startbootstrap.com)
I am new to coding and wanted to get some hands on practice with a project I have in mind. Here it is:
Let's say you have blank page and on the side of a screen you have several items you can choose to draw on the blank page. For example the background can be mountains, the ocean, a forest etc. On top of that you can place a house, a church or another selectable element. Whatever you like.
It is like a picture editor where you can put together a picture with different pre-given elements. Or like in video games where you can create your own character.
What would I need to build a web application for that kind of thing?
This link should get you started but it won't be the complete answer to your question - http://www.webdesignerdepot.com/2013/08/how-to-use-html5s-drag-and-drop/
Essentially, you can achieve your image dragging and dropping using similar techniques. It will require a bit of Spike work from yourself, and looking into how HTML5 can handle drag and drop. I discovered this resource fairly quickly and I think the solution you want isn't as complicated as you may think, it just requires a bit of know-how regarding drag and drop operations within HTML5 :-)
Also, there may already be some JavaScript based API's that do this sort of thing easier but I'm not too aware - I suppose starting this way could be a great introduction for you and you may wish to expand once you've done some work for it :-)
Hope this helps you and your coding journey!
I'm trying to add an image to MKMapView using SWIFT and I have ZERO coding experience. Could someone provide me with ALL the sample code necessary to do this? If there are any placeholder words (like overlay.yourimage.mapView) could you put the place where I need to add my information IN CAPS? I can't even tell the parts where I'm supposed to add my own information.
I appreciate any responses, I'm a first time poster.
Welcome to Stack Overflow.
The short answer is no.
This is not a site where people write your code for you. It's a site where you come when you have specific problems with code you've written and need help.
Be warned that MKMapView is a pretty complex framework. If you have zero programming experience it is way, way, WAAAAAAY over your head. You need to start with "Hello World" type stuff and work your way up.
Starting your programming career with trying to customize a map view is like going down a black diamond ski trail the first time you put skis on. You will fail dramatically, and won't be ready for black diamond trails (advanced APIs like map kit) until you do a lot of groundwork.
You can probably find sample code online that deals with adding an image to a map view, but it's not going to make much sense to you at this point, just like a ski instructor explaining how to get through a difficult mogul field won't make much sense to a beginning skier.
three.js comes with many useful controls, which cause camera movement in response to keyboard and mouse input.
They are all at https://github.com/mrdoob/three.js/blob/master/examples/js/controls and accessed in the code as e.g.THREE.OrbitControls .
However, I can't find any documentation or comments that says what situation to use what control for or what they are intended to do.
Can anyone point me to this information, or do I have to analyze the code to figure out if, for example, I prefer FlyControls to FirstPersonControls?
The documentation for the controls does exist, but it was deleted from the repository here. Seems like a bizarre thing to do, but there is an explanation of sorts here. I guess the docs were very incomplete anyway and it was easier to delete them than to finish them. :-p
The source code for most of the controls contains pretty decent comments. I know this isnt as good as proper documentation but it really helps to get a handle on how to set up the controls
The Controls are named by their purpose or the idea they implement. OrbitControls allow you to orbit around some kind of object. Same for Trackball-Controls although the trackball-scheme implies that the camera will rotate around without the up-Axis staying as it was like in orbit-controls. Fly and FPS-Controls are self-explanatory.
Just try the examples and you will see what the difference is. No need to analyse code. Just depends on what you want to achieve.
I am new to OpenGl, almost new to C++.
I am looking for some code that does the following things.
Open an OpenGL window (maybe using glut)
Rotate the view point when the user press the left mouse button
zoom when the user press the right mouse button
translate the point of view the user press the central button
Basically what I need is a very simple graphics platform in which I will plot results coming from my algorithms. I have tried using the glut library and some code coming from the web, but no luck!
This should be a basic project, can you please point me where to find it. It just seems unreal to me that a so simple project turns to be so hard to find, but I have been googling for hours and no results.
I really appreciate your help,
thank you very much
You're asking for a fair amount of code there. Basic, but not insubstantial. Even if we do provide the code to do what you've asked, I'm not sure if you'll be able to use it to do what you want. The Red Book is a "bible" of openGL programming of sorts and will provide you with many of the functions and how to use them. I found the entire thing online here. Look into Chapters 1-3 for your drawing and rotating. Also, Lighthouse 3D has some great tutorials for you to look at for mouse events (Link). Some knowledge of linear algebra really helps, but you can manage without it.
I don't think it directly implements everything you want, but you might want to look at the 3D graph control on Code Project. This is hardly unique though -- you might want to Google for something like "opengl activex" and look at some of the alternatives. I doubt any will directly implement all you've asked for -- they'll probably include most of the basic operations, but it'll be up to you to make the connection between the mouse operations and the actions in the window.
