Game Engine

Git ; No I didnt ;)

I figured out part of the problem from Plenderj's project, and Kedaman's post... Now the offsets are basically 100* the scale of the map (aka an offset of 10,9 is 1000,900).

I'm still having problems though, i can only go in the direction of about 315 degrees. Here's my source.

Code:

---

    Do
        GameForm.Cls
        If GetAsyncKeyState(vbKeyLeft) Then
            Cars(PlayerCar).Angle = Cars(PlayerCar).Angle - 1
            If Cars(PlayerCar).Angle < 1 Then Cars(PlayerCar).Angle = 360
        ElseIf GetAsyncKeyState(vbKeyRight) Then
            Cars(PlayerCar).Angle = Cars(PlayerCar).Angle + 1
            If Cars(PlayerCar).Angle > 360 Then Cars(PlayerCar).Angle = 1
        End If
        If GetAsyncKeyState(vbKeyUp) Then
            XOffSet = XOffSet + Int((Sin(100 * Cars(PlayerCar).Angle * 1.74532925199433E-02)))
            YOffSet = YOffSet + Int((Cos(100 * Cars(PlayerCar).Angle * 1.74532925199433E-02)))
        End If
        Dim XTemp2 As Integer
        Dim YTemp2 As Integer
        XTemp2 = 0
        YTemp2 = 0
        For XTemp1 = 1 + Fix(XOffSet / 100) - Fix((GameForm.ScaleWidth / 100) + 1) To 1 + (XOffSet / 100) + Fix((GameForm.ScaleWidth / 100) + 1)
            XTemp2 = XTemp2 + 1
            YTemp2 = 0
            For YTemp1 = 1 + Fix(YOffSet / 100) - Fix((GameForm.ScaleHeight / 100) + 1) To 1 + (YOffSet / 100) + Fix((GameForm.ScaleHeight / 100) + 1)
                YTemp2 = YTemp2 + 1
                If XTemp1 < 0 Or YTemp1 < 0 Or XTemp1 > MapXSize Or YTemp1 > MapYSize Then
                Else
                    BitBlt GameForm.HDC, (Fix(XOffSet / 100) * 50) - XOffSet + ((XTemp2 - 1) * 50), (Fix(YOffSet / 100) * 50) - YOffSet + ((YTemp2 - 1) * 50), 50, 50, PicSource(0).HDC, (Map(XTemp1, YTemp1, 1).Type - 1) * 50, 0, vbSrcCopy
                    BitBlt GameForm.HDC, (Fix(XOffSet / 100) * 50) - XOffSet + ((XTemp2 - 1) * 50), (Fix(YOffSet / 100) * 50) - YOffSet + ((YTemp2 - 1) * 50), 50, 50, PicSource(1).HDC, (Map(XTemp1, YTemp1, 1).Type - 1) * 50, 0, vbSrcCopy
                End If
            Next YTemp1
        Next XTemp1
        Dim CarWidthOffsetCount As Integer
        Dim CarWidthOffsetWidth As Integer
        CarWidthOffsetWidth = 0
        For CarWidthOffsetCount = 1 To PlayerCar - 1
            CarWidthOffsetWidth = CarWidthOffsetWidth + CarTypes(CarWidthOffsetCount).Width
        Next CarWidthOffsetCount
        'CarBlitCodeHere
        GameForm.Refresh
        Sleep 50
        DoEvents
    Loop

Anyone know what's wrong? FYI the Sleep 50 is in there cause this is a BIT fast on my Duron 800. ;)

Well...
Why not just copy the code out of Craft and blit your car instead of a spaceship :)

Anyway, in relation to the Sleep part, why dont you use some GetTickCount().

IMHO, Thats the best way of slowing down games.

Thake a look at my "Dilemma" post. its somwhere on thise forum. It should help you out (try both formulas that are there, the one that shouldnt work, and the one that makes sense). Also, there is code in there to create a lookup table, so you dont have to call sin and cos (they are slow). Hope that helps.

Also, 1.74532925199433E-02 = PI / 180. Make your life easy, and create a constant. =)
