| obj.SetSpeedX(10) If (obj.xPos >450) Then obj.SetSpeedX(-10) How come my obj. stuck in one place. It's like its trying to move but it cant. |
| ||
| are you adding speedx to the position of your object? |
| ||
| I'm trying to make the object to move back (bounce) |

obj.SetSpeedX(10) If (obj.xPos >450) Then obj.SetSpeedX(-10) 1. try setting the if/then on one line. using "Then" with "If" is usually one line. use "If" and "EndIf" if using multiple lines. 2. you should SetSpeedX to "0" unless your function is cumulative "speed=speed+myNewSpeed". |

| If you always set speed to 10 and only set speed to -10 when the object is over the border, the object will not return, but keep staying at the border! Try this: If obj.xPos<0 Then obj.SetSpeedX(10) If obj.xPos>450 Then obj.SetSpeedX(-10) This needs a definition of SpeedX when creating the object. Method New()
...
Self.SpeedX=10
And it works only if there is anywhere a line with... obj.xPos=obj.xPos+obj.SpeedX By the way... I would encapsle all this things into the Object-Class OnRender()
obj.Draw()
....
End
Class Object
Field SpeedX%=10, xPos%, yPos%
Method Draw()
DrawRect xPos,yPos,5,5
xPos=xPos+SpeedX
CheckBorders
End
Method CheckBorders()
If xPos<0 Then SpeedX=10
If xPos>450 Then SpeedX=-10
End

| Nicolas, by any chance. Are you using fantomEngine in your app? |
