Hey all,
having a bit of a problem with a mini RPG sample game I am converting from a mac C++ sample (though I don't know C++ so I am doing the whole thing from VB in scratch, those of you who read "Tricks of the Mac Game Programming Gurus" would have seen this). I have barely gotten into this game yet because I am having trouble with the basics..."movement", also this would be an easy task to accomplish with the keyboard, with with mouse this type of collision detection proves more difficult (for a novice like me anyways :)). If you all look in the Picture1_MouseDown procedure
-------------------------------------------------------
Dim OldX As Integer
Dim OldY As Integer
Dim MonsterIndex As Integer
Dim NewTerrain As Integer
OldX = Chars(0).X
OldY = Chars(0).Y
If (X / 32) > (Chars(0).X + 1) Then
Chars(0).X = Chars(0).X + 1
End If
If (X / 32) < Chars(0).X Then
Chars(0).X = Chars(0).X - 1
End If
If (Y / 32) > (Chars(0).Y + 1) Then
Chars(0).Y = Chars(0).Y + 1
End If
If (Y / 32) < Chars(0).Y Then
Chars(0).Y = Chars(0).Y - 1
End If
NewTerrain = TerrainVal(Mid(MapValues(Chars(0).Y), Chars(0).X, 1))
If NewTerrain = 1 Then
Beep
Chars(0).X = OldX
Chars(0).Y = OldY
ElseIf NewTerrain = 2 Then
GetGold Chars(0).X, Chars(0).Y
ElseIf NewTerrain = 3 Then
End
End If
'If IsMonster(Chars(0).X, Chars(0).Y) Then
' MonsterIndex = MonsterAt(Chars(0).X, Chars(0).Y)
' Chars(0).X = OldX
' Chars(0).Y = OldY
' Attack 0, MonsterIndex
'End If
'RandomizeMonsters
PaintMap
End Sub
-------------------------------------------------------
(The whole project file is available on the site mentioned at the end of this post)
I have tried many variations of this method, however this one seems to be the only light of hope. However it seems that it always detects walls (NewTerrain = 1), though if the following lines are commented out
If NewTerrain = 1 Then
Beep
'Chars(0).X = OldX
'Chars(0).Y = OldY
it moves quite smoothly, however you can tell it is still constantly thinking that you are on a wall which is proven by the ever annoying "Beep". Turn these lines off and you quickly find out that you cannot move far at all.
I know this method works fine with the keyboard, but the mouse is the wave of the future :), so I really wanna get that going for this sample :) :). PLuS the original Mac C++ sample used the mouse and I wanna make an exact replica of it for practice, and likely turn it into a PSC code tutorial.
Any help is appreciated and will be added to the "Credits" section of the game (once I get the menu created, heh).
And I know that code snippet above doesn't tell you guys much so I'll post the whole project here:

BTW I am using VB3 for this code simply because I usually code on an older machine (for now anyway), however I have also included a VB6 version in the above zip file.
Any questions or comments send to "alyien@yablue.com" or simply reply to this post ^_^.
Keep VBing everyone |
