Query - Drawing to Camera/View - camera_get_active() vs. view_camera

[Bulletech]

I was recently 'pulling my hair out' trying to figure out why my code for drawing a cursor (without mouse_x and mouse_y) to a camera view wasn't working... and I'm still not sure.

I was using functions like camera_get_view_x(camera_get_active()); as suggested in a YT video I found "Using and Drawing With Views in GameMaker Studio 2 Tutorial" and no matter what I did it wasn't working as expected, even though my debug to see what the function was returning seemed fine.

I then found view_camera[0...7] in the GameMaker Manual and tried camera_get_view_x(view_camera[0]); and so on instead and it worked with no issues. But I'm not sure as to why? I think it might've been an issue with switching between rooms with no cameras/views to a room with a camera/view?

example code where view_camera[0] works, but camera_get_active() doesn't:

if (cursor_x < camera_get_view_x(view_camera[0]))
{cursor_x = camera_get_view_x(view_camera[0]);}
if (cursor_x > camera_get_view_x(view_camera[0])+camera_get_view_width(view_camera[0]))
{cursor_x = camera_get_view_x(view_camera[0])+camera_get_view_width(view_camera[0]);}
if (cursor_y < camera_get_view_y(view_camera[0]))
{cursor_y = camera_get_view_y(view_camera[0]);}
if (cursor_y > camera_get_view_y(view_camera[0])+camera_get_view_height(view_camera[0]))
{cursor_y = camera_get_view_y(view_camera[0])+camera_get_view_height(view_camera[0]);}

When you say it didn't work, do you mean it was drawing your cursor in all views rather than just one? All cameras are active every draw event; you have to check the id of the currently active one. By using view_camera, you are essentially limiting it to the particular camera.

 

[Bulletech]

No not specific to drawing the cursor, more to do with checking where the cursor is, like the example code above

If you want a custom cursor use:
window_set_cursor(cr_none);
draw_sprite((CursorSprite),0,mouse_x,mouse_y);

If you want a custom cursor use:
window_set_cursor(cr_none);
draw_sprite((CursorSprite),0,mouse_x,mouse_y);

The first line of OP says: "trying to figure out why my code for drawing a cursor (without mouse_x and mouse_y)"
