I'd like to move an image horizontally to the middle of the screen, stop and wait x seconds and then continue moving off the screen.
matibee posted a nice chunk of code :
SuperStrict
Type lerpStage
Field startTime:Float
Field endTime:Float
Field startPos:Float
Field endPos:Float
Function Create:lerpStage( st:Float , et:Float , sp:Float , ep:Float )
Local ls:lerpStage = New lerpStage
ls.startTime = st
ls.endTime = et
ls.startPos = sp
ls.endPos = ep
Return ls
End Function
Method Position:Float( time:Float )
Local t:Float = time - startTime
t :/ endTime - startTime
Return startPos + t * ( endPos - startPos )
End Method
End Type
Type LerpAnimator
Field stages:TList
Field time:Float
Field lastMS:Float
Function Create:LerpAnimator( stage:lerpStage )
Local la:LerpAnimator = New LerpAnimator
la.stages = New tlist
la.stages.addlast( stage )
Return la
End Function
Method addStage( stage:lerpStage )
stages.Addlast( stage )
End Method
Method Update()
time :+ 0.001 * Float(MilliSecs() - lastMS)
lastMS = MilliSecs()
End Method
Method Position:Float()
For Local ls:lerpStage = EachIn stages
If ( ls.startTime <= time And ls.endTime >= time )
Return ls.Position( time )
End If
Next
Return lerpStage( stages.Last() ).endPos
End Method
Method Start()
lastMS = MilliSecs()
time = 0
End method
End Type
Graphics 800 , 600
Local animator:LerpAnimator = LerpAnimator.Create( lerpStage.Create( 0 , 1 , 800 , 300 ) )
animator.addStage( lerpStage.Create( 1, 6 , 300 , 300 ) )
animator.addStage( lerpStage.Create( 6 , 7 , 300 , - 200 ) )
animator.Start()
While Not AppTerminate()
Cls
DrawRect animator.Position() , 200 , 200 , 200
DrawText animator.Position(), 0, 0
Flip 1
animator.Update()

This is similar but probably over complicated for me. Any simple examples ? Thanks.
