[EO2.x] Roof System

[Justn]

Ok this is a simple roof system. Basically it adds a new layer, the roof. When I player steps on the new threshold tile attribute the roof layer is invisible.. This was ripped from Alatar’s house system so all credits to him..

**Server-**

**modConstants**

Add this to the bottom of your tile constants:

```
Public Const TILE_TYPE_THRESHOLD As Byte = 15
```

**modEnumerations**

Find : **Public Enum MapLayer** and add this before the layer count:

```
Roof
```

**Client-**

**modEnumerations**

Find : **Public Enum MapLayer** and add this before the layer count:

```
Roof
```

**modDirectDraw7**

Find: **' blit out upper tiles**

Under: Call **BltMapFringeTile(X, Y)** add this:

```
Call BltRoof(X, Y)
```

Next add this to the bottom of **modDirectDraw7**:

```
Public Sub BltRoof(ByVal X As Long, ByVal Y As Long)

Dim rec As DxVBLib.RECT

Dim i As Long

With Map.Tile(X, Y)

i = MapLayer.Roof

If .Layer(i).tileset > 0 Then

rec.Top = .Layer(i).Y * PIC_Y

rec.Bottom = rec.Top + PIC_Y

rec.Left = .Layer(i).X * PIC_X

rec.Right = rec.Left + PIC_X

If Not Threshold = True Then

Call Engine_BltFast(ConvertMapX(X * PIC_X), ConvertMapY(Y * PIC_Y), DDS_Tileset(.Layer(i).tileset), rec, DDBLTFAST_WAIT Or DDBLTFAST_SRCCOLORKEY)

End If

End If

End With

End Sub
```
**modText**

Find:

```
Case TILE_TYPE_SLIDE

DrawText TexthDC, tX, tY, "S", QBColor(BrightCyan)
```

Under it add this:

```
Case TILE_TYPE_THRESHOLD

DrawText TexthDC, tX, tY, "T", QBColor(BrightCyan)
```

**modGameLogic**

Find this:

```
' Check to see if the map tile is blocked or not

If Map.Tile(X, Y).Type = TILE_TYPE_BLOCKED Then

CheckDirection = True

Exit Function

End If
```

**Above** it add this:

```
If Map.Tile(X, Y).Type = TILE_TYPE_THRESHOLD Then

Threshold = Not Threshold

Exit Function

End If
```

**modConstants**

Add this to the bottom of your tile constants:

```
Public Const TILE_TYPE_THRESHOLD As Byte = 15
```

**modGlobals**

Add this to the bottom:

```
Public Threshold As Boolean
```

**modGameEditors**

Find this:

```
' slide

If frmEditor_Map.optSlide.Value Then

.Type = TILE_TYPE_SLIDE

.Data1 = MapEditorSlideDir

.Data2 = 0

.Data3 = 0

End If
```

**Below** it add this:

```
' Threshold

If frmEditor_Map.optThreshold.Value Then

.Type = TILE_TYPE_THRESHOLD

.Data1 = 0

.Data2 = 0

.Data3 = 0

End If
```

**Form Work-**

**frmEditor_Map**

First add this code to the bottom of **frmEditor_Map**:

```
Private Sub cmdRoof_Click()

Threshold = Not Threshold

End Sub

Private Sub optThreshold_Click()

' If debug mode, handle error then exit out

If Options.Debug = 1 Then On Error GoTo errorhandler

ClearAttributeDialogue

picAttributes.Visible = False

' Error handler

Exit Sub

errorhandler:

HandleError "optThreshold_Click", "frmEditor_Map", Err.Number, Err.Description, Err.Source, Err.HelpContext

Err.Clear

Exit Sub

End Sub
```

1.Now in the frame: **fraLayers.** Copy and paste one of the map layer radio buttons (make sure to paste inside of fraLayers) and set the index to 6 (or the next number if u have more layers).

2.Next create a **command button** in **fraLayers** and name it: **cmdRoof**

Set the caption to: **Roof**

3.Find the **map attributes** and create a new radio button on **fraAttribs**. Name it: **optThreshold**

And that should be it.. Its pretty basic and the only issue I can think of is one found here:

[my one issue](http://www.touchofdeathforums.com/community/index.php?/topic/128934-function-for-getting-the-players-last-position/)

If anyone has a solution for that it would be perfect but still works well as is….

I actually really like the idea. I'll have to try it out.

[tslusny]

Of course this is from house system right?  But gj i was always too lazy to rip it 

[Murdoc]

This is great, thanks for sharing.

[Whackeddie99]

Damn, I programmed one from scratch into Cinder. Oh well, I guess you can't make something unique anymore these days.

[lollicat]

Not sure if this is an error or me being stupid. In the client,

"Compile error: Method or data member not found"

Highlights ".value" in If frmEditor_Map.optThreshold.value Then within modGameEditors

Believe it or not there are about 9000 other games that also have the same system.

Also I think that instead of completely making the layer invisible, putting its alpha down would look much better.

When i said unique, I mean't unique to eclipse.

*Sigh* exactly what I did. You guys are killin me

[Justn]

What do u mean by putting the alpha down? Sorry I'm.slow

[Guest]

Making it transparent.

[Justn]

Oh.. but this was intended for dx7 so I take it thats not possible :/

[hisherwin]

i suggest to make 2 attribute for roof system , so there will be no issue , AnonMica did 2 Attribute 1 attribute is to remove the roof layer and the second is to make back what it really looks like , And we also add a saveoptions system on the roof system , So when they are inside the house and log out , the roof will be on what it looks like before you log out..

sorry for my english

[Justn]

Yea that's what I was thinking about doing just seems like a waste of tile space though.. might just do that tonight :/ wish there was a better way

[hisherwin]

Actually that was a better way 

[Zetasis]

Ignore this I'm retarded.

Make a single tiletype and just alternate between the two states of visibility as you move over it.

[Justn]

> Make a single tiletype and just alternate between the two states of visibility as you move over it.

That's what it currently does though?

[Kemerd]

It makes a layer over other layers, that when you step on a certian tile, it makes it look like you stepped inside the house, or makes that tile disappear.

[Justn]

I'm confused are u asking a question? 

[Stein]

> That's what it currently does though?

Then what's the problem? I'd reckon that works just fine. Adding another tiletype would just be a waste.

[Justn]

Yea i know having another tile type is a waste thats just how it is in sherwins project…

I know its not a huge deal but with the way it is now u can step on the tile type turn back around and walk out of the house and since u didnt step on tile a second time the roof layer is still gone yet ur outside or if u did it the other way ur in the house with the roof on.. just alittle unrealistic 

[Stein]

Could always set up a directional parameter for it. Say, if you walk OFF OF it facing direction x it switches off, and direction y switches it on.

[Justn]

Ah yea that's what I was trying to do basically but ur way seems much easier ill try it

[Ganjika]

Are there any screenshots of this? - That would be epic. =]

[PVJsquad]

must delete all maps ?
