Does this have audio? Can you hear the heartbeat?

 

@kenlem: It doesn't at the moment as I wasn't sure if this would be annoying, but it is easy to do so I'll add it to the next version with an option to turn it on and off.

 

Very interested but would love to see a video of it an action first.

 

@UnleadedGames: That's not a problem. I'll put up a couple of videos for you.

 

How many drawcalls does this add?

 

This looks really nice! Cant wait to see a video of it.

 

I'm intrested too, but i need to see the video and some more details, like draw calls, how easy is to change it my way, a tutorial to add the asset...

"will that blood come too?"

 

@fholm
@fano_linux: Depending on what you set the heart rate to it will only add between 2 and 3 calls.

@Tapgames: Just looking at getting a video up soon for you to see it in action, but no unfortunately the blood doesn't come with the package

 

SketchWork: This makes it essentially useless for mobile tho, since 3 drawcalls (and also the "dot" I assume) is way to much to pay for such a small effect =(

 

@fholm: That does include the dot, but I'll look at ways to maybe reduce this for mobile.

 

Bought and checked the source. You're going to want to get rid of the call to instantiate for mobiles.

 

@kenlem: Thanks for the purchase and more importantly the feedback. I'll look at adding some additional optimisations.

Thanks again.

Justin

 

@UnleadedGames
@Tapgames
@fano_linux: Added a demo video to the top post.

 

Package updated with some additional documentation.

 

Thank you for the video, would there be any reason this wouldn't work in Unity 3.5.7 if I were to import it into Unity 4 then move it my Unity 3.5.7 project folder?

 

@UnleadedGames: There should be no reason at all. It only defaults to Unity 4 because that is what I exported it from, so should work perfectly

 

I have added some mobile optimisation notes. For mobile users if you turn off the blip you can get the number of draw calls down to 1 to 2. I'm looking at getting this to just 1 for the next release for mobile users.

Have fun and happy new year everyone.

 

New version with full heart sound effects and flatline sound effect submitted to asset store. Waiting for approval

Enjoy!

 

My only problem is that the rhythm strip is not a normal baseline, other than that its pretty cool. A heart beat monitor would show a P wave, QRS complex, and a T wave. Right now your player does not have a P wave, so no AV node depolarization. You also have a lot of noise or artifacts between the beats. The strip should be completely clean between beats, unless of course he has a heart block in which case he will need surgery or die.

Your normal sinus rhythm should look like this http://www.richacls.com/blog/wp-content/uploads/2010/07/Normal-Sinus-Rhythm.png

Dont forget, although your hear rate increases, there should be no change in the appearance of the lines. The only change would be that the beats would be closer together. Any variation in the beats would indicate a problem with the heart.

 

@hellraizerhhh: Thanks for the feedback. I think I was originally going for a more fictitious look and feel, but I think what I'll do is add an option for a realistic baseline too. I'll make the adjustments for the next version. My wife is a nurse - maybe I should have asked her to take a look too

Thanks again.

 

Version 1.4 has been submitted to the Asset Store and now features full sound effects which of course can be turned on and off as needed.

First post updated with release notes.

 

Thank you to everyone who has purchased this asset so far. Version 1.4 has gone live in the asset store today which now includes full sound effects.

Enjoy and thanks again.

 

I put the heart monitor as health bar in my game and it was pretty cool, here's a video (you can see the monitor on top of the tablet, when the camera zooms). It was very easy to use.

 

i got a problem with blip monitor height if i set it low ( 0.01) the beats become random and not on the same level
also i can't find a way to make it in the same position in the screen, every time i change the reselotion it gets off place.

 

I'll take a look for you, can you post an image showing where you are trying to put it and the size of it.

 

I have checked and if you are changing the Height Modifier to 0.01 it makes the blip peaks very small so you can't really see them.

The control is just like any other control in regards to position so if you want it to always been in the centre and at the top of the screen (like Renan Reis's example above) you can calculate the screen size and divide by 2 to get the centre and position accordingly. If you just position it in the inspector and move the camera at runtime the control will also move unless you have a dedicated GUI camera which doesn't move, but you will still need to calculate the position if the resolution changes.

 

if i set it anything bigger it will take more space than it should, i need it to be in the top left screen, here is how i am doing it :
there is a separate camera for my UI
i added a NGUI sprite then i attached UI anchor script (so it stay at the top left all the time) then i added the SWP script to the sprite.
the sprite stay as it should no problem but the heart beats do not.
here at 0.01


and here with 0.06

 

I few things that might be worth taking a look at.

How are you shrinking the controller? If you are using a perspective camera have you tried pushing it back on the Z position or the projection size if using an orthographic camera instead of shrinking it drastically using the monitor width and height modifiers and then use the modifiers to fine tune?

Also, NGUI will create you an orthographic camera with a projection size of 1 which could be why your heart controller is so huge to begin with and I think the reason why your heart line is moving around is probably because the HeartMonitorBlip and HeartMonitorTrail prefabs are being created on the default layer and are being rendered with the default scene camera which is not effected by the anchor.

Last thing, have you checked out Example 1 (Overlay) as this looks pretty much what you are trying to accomplish with regards to size. You'll just need to anchor it to the top left and you are done.

Let me know how you get on.

Take care and all the best. Justin

 

thanks for the support
i got the position to work after adding an empty game object and make it serve as a pivot for the HRM then i attached the UIAnchor script to it.
the only remaining problem now is NGUI camera size, how do i fix this ? do i must add a third camera to my game ? isn't making a camera only for this is a huge performance loose ?

 

Glad you sorted out the anchoring. If the camera is only going to project the HRM and cull everything else then there should not be any performance loss. Give it a try and let me know how it goes. All the best, Justin.

 

Thanks for this little plugin. Can you provide a simple example of how to set the bpm variable with a javascript script? I'm pretty new, and I really don't know how to interface c# variables with javascript (which is the only option for me right now).

Thanks!

 

Firstly, thanks for the purchase - much appreciated.

No problem at all. I'll put together a quick example for you tomorrow on how to interface with Javascript.

 

Thanks a ton SketchWork. And thank you for the quick reply.

 

@GREBENOTS:

To access from JScript you need to put the SWP_HeartRateMonitor c# script into the plugin folder.

1) In the root of your project create a folder called Plugins (if not already there)
2) Create a folder inside the new Plugin folder called SWP_HeartRateMonitor
3) Move the script SWP_HeartRateMonitor \ Scripts \ SWP_HeartRateMonitor.cs file into this new folder so it should now be:

Plugins \ SWP_HeartRateMonitor \ SWP_HeartRateMonitor.cs

This makes sure it is compiled into the editor for use in JScript

4) Now you should be able to access it from your own JScript files. For example: Open the SWP_HeartRateExample1(FullScreen) project.
5) Create a new JScript file and add the following code:

Code (csharp):

1.  
2. #pragma strict
3.  
4. var HeartBeat: SWP_HeartRateMonitor;
5. private var HeartBeat2: SWP_HeartRateMonitor;
6.  
7. function Awake()
8. {
9.     HeartBeat2 = GameObject.Find("HeartMonitor").GetComponent(SWP_HeartRateMonitor);
10. }
11.  
12. function OnGUI()
13. {
14.     if (GUI.Button(Rect(10,10,120,50), "SPEED UP"))
15.         HeartBeat.BeatsPerMinute = HeartBeat.BeatsPerMinute + 20;
16.  
17.     if (GUI.Button(Rect(10,60,120,50), "SLOW DOWN"))
18.         HeartBeat2.BeatsPerMinute = HeartBeat.BeatsPerMinute - 20;
19.  
20. }
21.  

5) Add a empty game object and add the new script to it
6) Drag the HeartMonitor GameObject into the HeartBeat variable on the new gameobject.
7) Run. One button will speed it up and the other will slow it down. The script uses 2 different methods of calling the HeartBeat:
i) By inspector assignment (var HeartBeat)
ii) By assigning with code (private var HeartBeat2)

I hope this makes sense

 

Thanks again for your quick reply. I'll be able to get it tested tomorrow, but the code makes perfect sense, so I'm sure it will work. I'll let you know though.

 

OK who am I kidding here, I tested it right away! Anyways, your directions work a charm. Thanks again.

Will a future update allow the capability to change the color of the lines? Green is ideal for my current app, but I may use this in a future app where I'd like to change colors.

 

@GREBENOTS:

Really glad you got the JScript working. The colour changer is on my list of todo's so should be available for my next release

Please if you have time give me a little review on the asset store page: https://www.assetstore.unity3d.com/#/content/6034

- thanks again.

 

Version 1.5 is now live in the Asset Store and now has support for both Unity 3.5 and Unity 4+.

If you have any questions please ask. I am UK time (GMT) and available throughout the day.

All the best,

Justin

 

Added another YouTube demo (Use for our Time Controller) and features the Heart Beat Monitor. The changes to AngryBots which I used in the demo took only about 5-10 minutes to add complete time control and the Heart Beat.

Video Demo

Enjoy!

Could you make a webplayer version to test it ?

 

@CoderPro Shouldn't be a problem. I'll put one up somewhere for you.

Justin

 

Is it possible to add it to a UI canvas? And move with the canvas animations?

 

Hi @Qwak , at present it is an actual 3D asset so doesn't rely on any form of GUI (UGUI, NGUI, EZGUI, etc). I am however looking at adding a way to add the asset to a Unity Canvas for a future version. I'll post here when this work is completed.

Best regards, Justin.

 

Thats great news!
I'll be waiting.

Thanks!

 

Very nice asset!

I made some tweaks. I added a transparent background sprite behind the HRM.



I added this to set color directly:

Code (CSharp):

1.  
2.     public Color HeartRateColor = new Color(0f, 1f, 0f, 1f);
3.     private Color testHeartRateColor = new Color(0f, 0f, 0f, 1f);
4.  
5.     void Update()
6.     {
7.  
8. ...
9.         if (HeartRateColor != testHeartRateColor)
10.         {
11.             MainMaterial.SetColor("_TintColor", HeartRateColor);
12.             testHeartRateColor = HeartRateColor;
13.         }
14.     }

And created a small class to do some custom animation based on bpm.

Code (CSharp):

1.  
2. using UnityEngine;
3.  
4. public class HRMAnimate : MonoBehaviour
5. {
6.     public AnimationCurve soundAnimationCurve;
7.     public AnimationCurve redChannelAnimationCurve;
8.     public AnimationCurve greenChannelAnimationCurve;
9.  
10.     private SWP_HeartRateMonitor _hrm;
11.     private int _testBPM;
12.     private float _bpmFloatVal = 0f;
13.  
14.  
15.     public void Start()
16.     {
17.         _hrm = GetComponent<SWP_HeartRateMonitor>();
18.  
19.         if (_hrm == null)
20.             Debug.LogError("HRM not found");
21.  
22.         _hrm.BeatsPerMinute = 60;
23.     }
24.  
25.     public void Update()
26.     {
27.         if (_hrm.BeatsPerMinute != _testBPM)
28.         {
29.             _testBPM = _hrm.BeatsPerMinute;
30.             _bpmFloatVal = (float)_testBPM / 240f;
31.  
32.             Debug.Log("BPM changed. BPM: " + _testBPM + ", volume: " + soundAnimationCurve.Evaluate(_bpmFloatVal));
33.  
34.             _hrm.SoundVolume = soundAnimationCurve.Evaluate(_bpmFloatVal);
35.  
36.             _hrm.HeartRateColor = new Color(redChannelAnimationCurve.Evaluate(_bpmFloatVal),
37.                 greenChannelAnimationCurve.Evaluate(_bpmFloatVal), 0);
38.         }
39.     }
40. }
41.  

Some fun stuff to add might be random arrythmias when bpm is > 200.

 

You need to add this bit to CreateClone for the blip and trail to appear on the correct layer:

Code (CSharp):

1.         NewClone.layer = gameObject.layer;
2.         NewClone.transform.GetChild(0).gameObject.layer = gameObject.layer;
3.  

 

it not auto scale like Ugui
How i can do it ?
