How To Make GUI/Dragable Object - Att: Video
Hello,
Basically, Right now I have a very simple GUI with a button. What I would like to do is to have that button to be able to be dragged to the scene, in where it will turn into a game object that follows the mouse.
Watch This To See What I Mean: http://olliejones.com/GUIHelp.mov
Like an inventory, but the reversal. So instead of picking up things from scene. I want to be able to drop onto scene from GUI. Preferably with a grid snap feature such as the one shown in the video.
Please help, or point me in the right direction.
Thanks
It doesn't have to be a button in the GUI - Later on, it will soon be a texture of some sort *
I haven't - I mealy edited it slightly and placed a bounty on it.
Oliver, instead of pasting code, I thought it would be more helpful to send you the scene I've created so that you would understand it better. So I've sent it to your email.
Break it down:
- Drag and store which item was dragged
- Detect where it is dropped
- Convert drop location from screen to world coordinates
- Snap the 3d position
- Create an object based on which item was dragged
Here are some tips:
setup: Use a GUITexture so you can use OnDrag, store a reference to the prefab you want to create inside that object.
- store the Prefab reference associated with the button inside OnDrag in a variable visible from (5.)
- Use Input.GetMouseButtonUp
- Use Camera.ScreenToWorldPoint
- Use the modulus operator for x and z coordinates
- Use Instantiate if your object is a prefab
This sounds like a good approach - I've only been scripting for about a week and I'm poor at making up code. So far I have tried receiving the mouses position according to the scene and having a prefab follow it but no luck there. Also tried initiating a prefab where I click - but that didn't even work too
You can use print statements to check that code is reachable and also to test values. Have a look at the parts which are broken, and ask yourself 'is this code getting executed?' and 'is this value what i expect?', then use print statements to confirm.
Yes, but it does not explain the scripts - I'm really bad at scripts - please help me!!
What I have given you should get you started. As requested I have "pointed you in the right direction". I don't mean any disrespect but we won't write your code for you. $$anonymous$$ake a start and ask specific questions if you get stuck on a certain step. Coding is not so hard, just give it a go and you'll be surprised how quickly you become quite good. :)
Im not very sure but this is experimentation that maybe will work
if ( Input.GetMouseButtonDown(0)){
var hit : RaycastHit;
var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
if (Physics.Raycast (ray, hit, 100.0)){
hit.collider.transform.tag = "drag";
//here you put when you clic to the GUI
}
}else{
if ( Input.GetMouseButtonUp(0)){
if (Physics.Raycast (ray, hit, 100.0)){
hit.collider.transform.tag = "drop";
//Here you put when you clic and that construction its build
}
}
}
Recomendation: For this its not sure to put a GUI in the script, it will be better if you do it in the scene.
why has people voted this one down? please remember to explain when you dont agree.
