[QUOTE=Skibur;44528367]Motion Blur do require render to texture, as well as other post processing effects. Even so, slapping a refraction texture on a plane in front your camera won't do, since refraction is also part of Unity pro feature.

To be honest, there has to be a good reason why you want motion blur for your game. It uses a lot of performance in terms of CPU processing.

Also, just a quick post, I can show you something.

Late reply but I am working on a racing game so it's definitely needed. I'll probably get pro near release if that ever happens, I've hit a bit of a hump lately with the mixed feedback I'm getting.

My school put Unity Pro licenses on two of our computers in class and I happen to be sitting at one.

Once I get back from spring break I will have time to mess around with some of the features that are locked in the free version. :dance:

Building a kind of tile editor :v

[unity]https://dl.dropboxusercontent.com/u/251205348/ShareX/2014-04/html.unity3d[/unity]

I think that's not that hard to use, [url]https://db.tt/KlHHm5gz[/url]
This support lighting and normal maps, it's really basic i guess...So at least use this for learn

How to use:

>Import package
>Create other: Tile Meshed
>Set the texture2d
>Set the normal map if you have one
>Set the tiles on x and Y

I recommend set the snap grid to 0.32f[/QUOTE]

I was making the same thing. I am using prefabs to instantiate it.
[IMG]http://puu.sh/89D3t.png[/IMG] [IMG]http://puu.sh/89Drd.png[/IMG] [IMG]http://puu.sh/89Dqu.png[/IMG]

But I have just one problem. If I instantiate a prefab it is not linked to prefab. So if I want to change example the texture so I have to make it one by one... that is annoying. I haven't solution for it right now :S

A script on one of my gameobjects is being disabled when I press play but I can't figure out why. Is there a way to find out what's calling the script.enabled = false?

Nevermind. I looked at the editor log file, found a null reference exception, and when I fixed that it started working again.

[QUOTE=sarge997;44507299]You should throw some Lerp on there, so it doesn't instantly pop to the wand.

Unless its a level 90 spell or something.. :v:[/QUOTE]

Just wondering, how exactly does Lerp work?
The code I have for getting the object is this:

        //Once in catch state, move the object to the player, go to Occupied state
        else if(physicsSpellState == PhysicsSpellState.Catch){

            rigid.MovePosition(transform.position + transform.forward * holdDistance);
            if(!(isSelectedSpell && SixenseInput.Controllers[1].GetButtonDown(SixenseButtons.BUMPER)))
                physicsSpellState = PhysicsSpellState.Occupied;
        }

        //When occupied, keep object in front of player, checks if bumper or trigger is pressed. If trigger, go to Charge state, else if Bumper go to Release state
        else if(physicsSpellState == PhysicsSpellState.Occupied){
            rigid.MovePosition(transform.position + transform.forward * holdDistance);

            if(isSelectedSpell && SixenseInput.Controllers[1].Trigger != 0.0)
                physicsSpellState = PhysicsSpellState.Charge;
            else if(isSelectedSpell && SixenseInput.Controllers[1].GetButtonDown(SixenseButtons.BUMPER))
                physicsSpellState = PhysicsSpellState.Release;
        }

Also, anybody have any ideas for other magic spells I can incorporate. I have 3 so far and I need a 4th.
Each spell has 2 functions: Light Spell(Pressure sensitive light, shoot light), Physics Spell(Levitation and force push), Fire spell(Fireball and flamethrower).

For the 4th I was thinking like a healing spell but its sort of lame.

Lerp works by interpolating two values by a number between 0 and 1.

So, for example. you do the following:

Mathf.Lerp( 0, 10, 0.5f );

The first parameter is the first value, the second parameter is the second value, and the third parameter is how much the two values should interpolate.

This example would return the number '5'. If the 3rd parameter was '0', the Lerp would return '0'. If the 3rd parameter was '1', the Lerp would return '10'. If the 3rd parameter was '0.25f', the Lerp would return '2.5f'.

What this allows you to do is smoothly move a thing from Vector3 A to Vector3 B as following:

    Vector3 A = new Vector3( 0, 0, 0 );
    Vector3 B = new Vector3( 10, 25, 201 );

    float TimeToLerp = 4; // The amount of seconds it should take to move something from A to B

    float lerpTimer = 0f;

    void Update() {
        lerpTimer += Time.deltaTime / TimeToLerp;   // We add the time since the last frame to the timer, and divide it by the amount of seconds it should take.
                                                    // If we keep adding Time.deltaTime, the lerp would take 1 second.

        transform.position = Vector3.Lerp( A, B, lerpTimer ); // Lerp from A to B by value. If lerpTimer goes over '1', it won't do anything.
    }

So what you could do is Lerp the object's original position to your wand's position by a certain amount of seconds.

Click on your prefab, make changes and then in Inspector, at top near Prefab label, click Apply, so changes will apply to all prefabs.

Ah okay that makes sense man thanks.
Any chance you could help me out with how I could get it working for the code I posted. I'm just not sure does it have to be before the rigid.MovePosition part or after it or what?

This is what I have but it does the same snap motion so sort of stuck with it

        else if(physicsSpellState == PhysicsSpellState.Catch){

            lerpTimer += Time.deltaTime / TimeToLerp;

    Vector3 originalPos;

    /**

        else if( physicsSpellState == PhysicsSpellState.Catch ) {

            // Add the seconds to the timer. The 0.5f means the lerp will take half a second no matter the distance from the object towards you.

That could happen if the value of TimeToLerp is 0. C# doesn't mind dividing by zero, but the result will be ∞

[QUOTE=TuLiq;44543759]Yes that is correct, however adding an outline shader to every material in my gameobject gives me outllines around every model, and I want the outline only to display around the bounds of my gameobject.[/QUOTE]

You can try combining mesh then applying shader on it?

[editline]16th April 2014[/editline]

Hey hey hey guys! I have one fucking annoying problem!

I have horrible stuttering with everything in game when VSYNC is turned on. (both Vblank and every second Vblank). Ok problem is everywhere. In editor and on all mobiles!

The stutter happen every second or every half second.. and it is very ANNOYING, I won't and can't move on until I fix this shit.

I mean c'mon, without vsync I get 1000FPS (PC) and on tablet (Nexus 7) it works smooth without vsync.

And I heavily doubt it is my code because:

1. Rigidbody: It is interpolated (unity rigidbody settings)
2. Visualbody: In Update function it is Lerped to Rigidbody. Both position and rotation
3. Camera: In LateUpdate it is Lerped to VisualBody. Both position and rotation

Also I removed everything heavy from scene to gain maximal FPS.

I'm having a collider problem here. When my game starts, my lander has an initial velocity even though there isn't anything in the scene for it to collide with or exert a force on it. I debugged the velocity magnitude and in OnStart(), the velocity is zero. In Update() the velocity is 0.07769718. So I checked for a collision and it is colliding with something even though there isn't anything to collide with.

I debugged the name of the colliding object; it's colliding with itself.
I debugged the InstanceID of the collider; it doesn't exist in the scene.
Debug.Log()'ing the gameObject.Find( instanceID).name throws a null reference exception.
I debugged the collision.relativeVelocity.magnitude and that's zero.

What the fuck?

So I started disabling components and shit and when I set the mesh collider to concave instead of convex, the problem disappeared. But I need it to be convex.

Any ideas?

Don't use a mesh collider or model the collision geometry manually (not sure if you've done this)?

Hard to say - the more the better. If you have experience with a different language, picking up C# as you go might not be a problem. If you've never programmed before, I would recommend following some more general "Learn C#" tutorials first to at least get a hang of variables, functions and classes. That said, there's things like [URL="http://catlikecoding.com/unity/tutorials/"]http://catlikecoding.com/unity/tutorials/[/URL] which seems to want to teach C# in the context of Unity scripting and that might work for you.

I found the problem. I was spawning another prefab then disabling it a frame later. That prefab and the lander were both spawning at the origin so they would spawn inside each other and shoot apart. No idea why the lander said it was colliding with itself though.

Pretty much any general-purpose software development bug/task tracker is suitable for game development.

I/we use Bitbucket for project hosting (usually), so tend to use its task tracker which is decent although simple (Attlassian would prefer you to buy JIRA).

I have also used bugzilla hosted on my web server which is good if you like looking at a website made by programmers (it "gets the job done" - what more could you want?) or have strange privacy concerns or something.

For smaller projects or having "unskilled" people involved you should consider a google spreadsheet, which with a small script or two you can get colour coding based on status/type and automatic sorting etc. (obviously the auto-sorting is not helpful if more than one person is trying to look at the thing). Speaking of which, if you want end users to be reporting bugs, google spreadsheet with form/s could be a good idea.
