Blood On/Off Button Tutorial by Craselin
Hey everyone,
before i start the tutorial I want say "MASSIVE" credit to Sweek who pretty much taught me how to do this and without him this tutorial would not exisit. Also please bear in mind this is my first tutorial.

**What does this tutorial do?**
This tutorial will guide you on create a checkbox in the options menu which allows players to turn blood on or off.
**Are there any known bugs?**
Yes, sadly there is a pretty big bug which causes blood not to appear on login until unchecking the box then re-checking it. There are no other known bugs.
**Is it hard?**
Not very hard it all, that is, if you follow the instructions.

>! **_ALL EDITS DONE IN CLIENT_**
**1\.** Open up client.vbp using visual basic professional or enterprise edition.
**2\.** In the project explorer click "Modules" then "modConstants"
**3\.** At the end of modConstants add this:
```
'blood on or off
Public bloodvisi As Boolean
```then close modConstants
**4\.** Once again in the modules section but this time open "modDirectDraw7"
**5\.** Find this code using Ctrl+F
```
Public Sub BltBlood(ByVal Index As Long)
Dim rec As DxVBLib.RECT
```Underneath it add this:
```
If bloodvisi = False Then Exit Sub
```then close modDirectDraw7
**6\.** Under the Forms section open frmMain
**7\.** Now for the more graphical part, in the corner you will see a big picture box (refer to picture below) right click it and select send to back, do this again until you see the music and sound options
**8\.** Now make a small label by clicking on the label button and place it below the other options, then click in the caption section at the side and name it "Blood" make the backstyle "0 - transparent" change the font to "georgia (bold)" and make the font colour "white (highlighted text)"
Then you need to make a checkbox next to the blood label, name it "bloodchk", make the backcolour "black (button text)" and change the value to "1 - Checked"
**9\.** Double click on the checkbox and a window should pop up, you should see a code like this:
```
Private Sub bloodchk_Click()
>! End Sub
```In the middle of that code, in the blank space, type (or copy) this:
```
If Check1.Value = 0 Then
BloodSwitch = True
Else: BloodSwitch = False
End If
```**10\.** Close that window and select File > Make Eclipse Origins.exe. A window should pop up so click ok then yes, now wait until the compile bar at the top is done. Now close VB6 (it will ask if you want to save, click yes)
**DONE!**

>! Oh and, sorry for the werid flashing at the start, Camstudio is werid like that sometimes.http://www.youtube.com/watch?v=4RoK29wV_VU

**GOOD LUCK! And enjoy!**
kind regards,

Perfectly written. I wish all the tutorials were in this format.

Thank you. Actually i might add a poll to see what more people think

There's no need, as long as you're happy with it yourself.

[Craselin]

Meh, i did it anyway XD

[Conra]

Nice tut! Anyway why will you turn blood off?

[Craselin]

I dunno, edgy parents? XD. I've just played some games where people have commented on not wanting blood. And thanks :D

[Conra]

Oh right! Awesome and no prob.

[Helladen]

You should use radio buttons and add a blood option to the OptionsRec and have it save this so it won't cause the bug you described above.

[Craselin]

Only one problem, i've got no idea how!? :/

[Helladen]

Can't really explain it well, try Ctrl + F OptionsRec, add Blood as Byte at the bottom of that. Then look for SaveOptions and LoadOptions, copy a line and rename the things to Blood.

After that copy a set of radio buttons and rename them, then set it and save options when it is modified.

You should know the basics of programming enough to figure this out on your own with this help though, don't feel like going through this in extreme detail.

You should also add the exit out where its called, because it would stop from calling the sub in the first place. So if the blood count is greater than 1 it would have to exit out as many times as what the blood count equaled.

[Craselin]

hmm, thanks. I'll look into that

[Conra]

DOnt you think it will slow your engine down a bit? Every time a player is supposed to "bleed" it checks whether "bleeding" is on or off. And it might be a little bit but it does affect the final speed of your client.

[Helladen]

No. The values are cached it takes like a millisecond to check.

[ToshiroHayate]

Ironically, Craselin has a bloody signature. XD

As for the tutorial, very nice. Should help quite a few people.

[Carim123]

An Option Button is simple.

Get rid of
```
If Check1.Value = 0 Then
BloodSwitch = True
Else: BloodSwitch = False
End If
```
And make two buttons, in one picture.

On the On button, simply put
```
Private Sub optBOn_Click()
        bloodvisi = True
End Sub
```
And on the Off, simply put
```
Private Sub optBOff_Click()
bloodvisi = False
End Sub
```
It's so simple even I got it, and I'm a programming wreck. It actually works.

EDIT: Although, this doesn't save it. Need to save it to the .ini.

oh. Someone told me differently today. :)

[Helladen]

@Conra:

> oh. Someone told me differently today. :)

I am not sure how fast it is to get the cached value, but I was trying to say that it is nothing to notice.

Thank you, i will test it and see if i can add a saved option

[gdog12356]

haha this is awesome. I love ur accent :D. It is really cool, you should add a tut to hide player names/levels lol.

[Craselin]

Hmmm, i just might do that :)
Thanks (and also, your like the 8th person to mention something about me accent to me XD)

i think if you add a few things that need checking it starts getting noticeable.

[Craselin]

@Conra:

Not really, think of it like this. How many lines of code does it take to say, you an item in EO or fight an NPC? The answer: quite a few, yet it still loads pretty fast.

nice tutorial, thanks :)
