hi am new in Android game development i use AndEngine i need to ploat a path but there is a problem
look at the image.The path i need is like the first one the object should move from the bottom to the middle of the screen.but while i plot my path it move to the middle of the screen but goes back to the 2nd point as in the Second image.The image is moving through the path but it is like the 2nd image.i need it as the first one.it should stop in the 3rd point and should start from the first point again.
My code is given below

please help me.Thanks in Advance
If you have three points you should specify it in your Path constructor:
instead
