Time.deltaTime and Texture.width

Questions & Answers
1

Hi,

I am trying to periodically “move” a texture from outside of the screen towards its center. The texture I am currently using is 500 px (but I will add more, later on, with various widths). In order to determine the coordinates of the rect (only x changes, not y), I am using textureName.width * Time.deltaTime in the Update function.
Given the multiplication I have to do with deltaTime, the final calculation is going to 515 pixels, which, as a result, moves the texture plus 15 pixels than the original plan.

//This runs in OnGUI()

if (startCounting) {
			GUI.Button (new Rect(Screen.width - infoX, Screen.height/2, infoPanel.width, infoPanel.height), infoPanel);
		}

//This runs in the Update()
if (infoX <= infoPanel.width) {
				infoX += infoPanel.width * Time.deltaTime;
			}

Mind telling me how to deal with this? I also want to add a static duration. I want the sliding to always last for 0.7 seconds, regardless of the texture’s width (which is how the calculation on infoX will deal out). I tried (infoPanel.width*Time.deltaTime)/0.7f, but given the aforementioned problem, I can’t get a precise calculation.

What can I do in this case?

Any reason you are using legacy? This task become trivial with the UI system. Simply create an image and Lerp Transform.position from the edge of the screen to the centre.
