I have this program that has an enemy walking back and forth on a platform. The display is in three parts, in the middle part the platforms scroll in the opposite direction of the player. This gives the illusion that the player is moving. When the player is in the mid zone and the enemies move at the opposite speed of the platform there appears to be no movement because they are set at 10 and -10. What I want is the platform enemy to continue to move back and forth at the same speed of the player character and bottom walking enemies. I tried changing the speed of the enemy to 20 and it moves back and forth, but it is to quick.

Here is the video:

Here is the code:

				platform::SearchVectorForPlatforms(vectorPlatforms, window, -10, 0.0f, 0);
				character.EnemyObject->moveEnemies(window, 20, -10, 0);

				character.gPlatformsMoved = "none";
			}
			else
			{
				miscObject.moveEnemies(window, 10, 0, 1);

				platform::SearchVectorForPlatforms(vectorPlatforms, window, 0, 0.0f, 0);
				character.EnemyObject->moveEnemies(window, 10, -1, 0);
			}

Sorry about the comments, thank goodness they appear dull.

I'm not understanding. Everything is 10 or -10 except moveEnemies that is changed to show motion. Does anyone else have an explanation, please?

Oh, fleabay, I have had much trouble trying to long on to this site. There seems to be real problems that keep surfacing. I would really appreciate if you could get the movement working. Its not that I think you are incorrect, it is just that I desire it to work at the apparent speed. I think the jump key was disabled when I was working on decoupling. I don't know why it wouldn't work in debug, probably something is different on your end, I guess. There are different libraries for release and debug on the SFML site. If you can fix it I would have some great experience totally! I have been meaning to get the jump working, when I do, I'll notify you.
