Syntax

nil dxCreateScrollingText ( float x, float y, float width, string text, int pixelPer60 )
 

Spoiler

• x: the absolute X coordinate of the top left corner of the text
• y: the absolute Y coordinate of the top left corner of the text
• width: An float representing the width of the text, drawn in a right direction from the origin.
• text: the text to draw
• pixelPer60: An float representing how much pixel should the text be shifted after 60 frames are gone.
