Hi everyone!
I was looking at the WalkingCharacter code, and I don't understand how it manages to change the image of the KID when he walks.
Can any of you tell me exactly how to do it? or send me an example?
In short, if a dynamic object wants me to change the sequence of images to the ones I want, I don't know how to do it.
best regards


Regards

Tip: start with X2 with B4J.

It happens in Kid.Tick:
B4X: 
Dim right As Boolean = bw.mGame.RightDown
    Dim left As Boolean = bw.mGame.LeftDown
    If right And left Then
        right = bw.FlipHorizontal = False
    End If
    Dim vx As Float
    If right Then
        vx = 3
        bw.FlipHorizontal = False
        IncreaseFrame = InAir = False
    Else If left Then
        vx = -3
        IncreaseFrame = InAir = False
        bw.FlipHorizontal = True
    Else if InAir = False Then
        vx = 0
    End If

The WalkingCharacter is quite complicated example.

The Mario example changes the graphics with this code (Mario class):
B4X: 
If InAir Then
            bw.GraphicName = GetGraphicName("jumping")
        Else If Abs(bw.Body.LinearVelocity.X) < 0.4 Then
            If bw.Body.LinearVelocity.X <> 0 Then bw.Body.LinearVelocity = x2.CreateVec2(0, 0)
            bw.GraphicName = GetGraphicName("standing")
        Else
            bw.GraphicName = GetGraphicName("walking")
        End If
And see Game.LoadMarioGraphics.
