Syntax

DrawAlphaLine( x as INT,y as INT,x2 as INT,y2 as INT,col as UINT,alpha as UINT,opt buffer as POINTER )

Description

Parameters

x, y - Starting coordinates of the line

x2, y2 - Ending coordinates of the line

col - Color of the line

alpha - Alpha blending value. From 0 to 255

buffer - Optional. Can be one of BACKBUFFER (default), FRONTBUFFER or SPRITEBUFFER
