This is really a nice example. You draw objects with your finger and they almost come to life: 288562763 Run with debug drawing to see the bodies structure: https://www.b4x.com/basic4android/images/SS-2018-09-06_18.25.59.png Note that chain shapes cannot collide with other chain shapes in box2d. Instead we create bodies with multiple polygon shapes. You can play with the angle interval to make it more accurate: X2.GraphicCache.PutGraphic2(gname, Array(sb), antialias, 3) The example...

In B4A the DrawBitmap method has a SourceRectangle parameter to draw a part of the source bitmap. In B4i the SourceRectangle parameter is missing. Same for DrawBitmapRotated. Is this an iOS limitation ?...

You can draw polygons with B4XCanvas.DrawPath. The following code calls B4XCanvas.DrawPath on B4A and B4i and calls a different method in B4J. DrawPath in B4J is slower than the other drawing methods... if you encountered a performance issue with B4XCanvas.DrawPath in B4J: 'Example Sub Page1_Click DrawPolygon(cvs, Array (Array As Int(100dip, 100dip), Array As Int(200dip, 0...)), _ xui.Color_Red, True, 2dip) cvs.Invalidate End Sub Sub DrawPolygon (cvs1 As B4XCanvas, Points...
