i consider myself as a new user for this darkbaic pro + dark ai. but i hope i can help u. Basically, u have to start with AI START NEW OBSTACLE, then u start to plot the 4 point of vertex in counter-clockwise if u are plotting for boundary, if u are plotting for obstacles, u have to plot in clockwise. after that u have to end it by AI END NEW OBSTACLE. If u are finish all the obstacles, then u have to call out AI COMPLETE OBSTACLES.
AI START NEW OBSTACLE
AI ADD OBSTACLE VERTEX -WIDTH#/2,-(DEPTH#/2)
AI ADD OBSTACLE VERTEX WIDTH#/2,-(DEPTH#/2)
AI ADD OBSTACLE VERTEX WIDTH#/2,(DEPTH#/2)
AI ADD OBSTACLE VERTEX -WIDTH#/2,(DEPTH#/2)
AI END NEW OBSTACLE 0,1
REM FINISH CREATING OUR BOUNDARY
AI COMPLETE OBSTACLES
i tried to create boundary for shape "F" but don't know it fail. so i just create with 4 vertex and add static obstacle within the 4 vertex to create the shape "F"..
