[edit] Definition
INT fget_dist ( <INT pointA-X> , <INT pointA-Y> , <INT pointB-X> , <INT pointB-Y> )
Returns the distance between two certain points.
[edit] Parameters
INT pointA-X | - The X-coordinate of point A. |
INT pointA-Y | - The Y-coordinate of point A. |
INT pointB-X | - The X-coordinate of point B. |
INT pointB-Y | - The Y-coordinate of point B. |
[edit] Returns
INT : The distance between point A and point B.
[edit] Example
Program angling; Const screen_width = 320; screen_height = 200; screen_depth = 8; screen_fps = 60; screen_frameskip = 0; Global int distance; int tempID; Begin // Set the screen mode set_mode(screen_width,screen_height,screen_depth); set_fps(screen_fps,screen_frameskip); // Change this to see what happens resolution = 100; // Create mouse graph, assign to mouse.graph mouse.graph = new_map(20,20,screen_depth); map_clear(0,mouse.graph,rgb(255,0,0)); // Create arrow, assign to graph graph = new_map(30,30,screen_depth); drawing_map(0,graph); drawing_color(rgb(0,255,0)); draw_line( 0,29,29,30/2); draw_line( 0, 0,30,30/2); // Set position x = screen_width /2 * resolution; y = screen_height/2 * resolution; // Display distance write(0,0,0,0,"Distance:"); write_int(0,60,0,0,&distance); // Always point to the mouse Repeat // Get the angle and distance between this process' coordinates and those of the mouse. angle = fget_angle(x,y,mouse.x*resolution,mouse.y*resolution); distance = fget_dist (x,y,mouse.x*resolution,mouse.y*resolution); frame; Until(key(_esc)) End
Used in example: set_mode(), new_map(), map_clear(), drawing_map(), drawing_color(), draw_line(), write(), write_int(), fget_angle(), fget_dist(), resolution, mouse, graph, x, y, angle
This example could also be done with get_dist(), but that would be more work. It also gives a much less accurate distance when the resolution is >1.
Resolution is 100:
