Question - Code Clamping the view

[spaceman_games]

I would use the 'view_xview = clamp...' function to stop the view from going out side of the room. But with the new functions I'm having a hard time figuring out what is a similar solution in GMS:2.

Any suggestions?

var cw = camera_get_view_width(view_camera[0]);
var ch = camera_get_view_height(view_camera[0]);
var vx = camera_get_view_x(view_camera[0]);
var vy = camera_get_view_y(view_camera[0]);
camera_set_view_pos(view_camera[0], clamp(vx, 0, room_width - cw), clamp(vy, 0, room_height - ch));

It's a lot more complicated, but definitely possible.

Yeah, it for sure if much more complicated! I actually tried using the camera_set_view_pos but I def didn't try making variables to hold the values. Can you not make it happen without make the local vars?

Thanks for the help by the way it does work very well.

Yes, simply replace the variables from the camera_set_view_pos() function call with the functions that I've called-and-assigned to them. But as you'd see, the code becomes unreadable and hard to follow, so I've used local variables to increase readability.

camera_set_view_pos(view_camera[0], clamp(camera_get_view_x(view_camera[0]), 0, room_width -camera_get_view_width(view_camera[0])), clamp(camera_get_view_y(view_camera[0]), 0, room_height - camera_get_view_height(view_camera[0])));

Oh yeah I see now haha. Much cleaner with the vars implemented.
