Additional Info:
This example shows how two objects are put into one view. It was made in simple GML, but with comments to make sure you know what is going on. It requires no credit whatsoever. Also, you can use the graphics without giving credit, which were made in seconds.
Here is the simple script to use when you want two objects in a view:

/*
TWO OBJECTS IN VIEW SCRIPT

No credit is required to use this simple script!
How to use: two_object_view(otherobject,viewnumber)

By: daman123125*/

view_hview[argument1]=(distance_to_object(argument
0)*1.5)+150 //sets the height of the view to the distance to the second object times 1.5 plus 150
view_wview[argument1]=(distance_to_object(argument
0)*2)+180 //sets the width of the view to the distance to the second object times 2 plus 180
view_xview[argument1]=((x+argument0.x)/2)-(view_wview[argument1]/2)//sets the x position of the view
view_yview[argument1]=((y+argument0.y)/2)-(view_hview[argument1]/2)// sets the y position of the view

hey thats a very nice example! I never hought it would be that easy to change the view like that. Everything is very well documkented except the script, which i think would need the most. I don't understand which parts of the script do what and why you chose those numbers :s
But it might just be me because I'm already busy making a game and trying to learn a thousand things at once so I don't have too much time to be tweaking code I wont need.

but i'll definetly find this usefull in the future! thanks alot!

[daman123125]

Ok. I've edited the first post to show the script, with comments.
Thanks for the comment.

[Snotrocket]

i totally get it now! thanks alot that was really helpfull!

[daman123125]

No problem.

I've been seeing a lot of people trying to get 2 objects in a view. Anyone else want to comment?

[Mocgames998]

Congratulations, you perfectly emulated the SSB camera system without much GML!

[daman123125]

Well, this tutorial only has two objects, and in SSB, there's 4 players...
But, anyways, thanks for the comment!

[deric007]

Very ce example!!

[appledave42]

Dude, ty. This is v. easy way but it works well. You could make it so the camera stays on screen, but I'll add that myself 4 my game.

[digidog08]

SSB Camera Lite!


A few request:
I am making an action battle sidescroller. I want the camera to focus on the closet object parented with par_enemy and the main player's object. And when it destroyed, set the view back to normal until another object parented with par_enemy is close.

I also want it to set the view back to normal if the distance_to_object(hero) and any instance with the parent "par_enemy" is out of view (or 400 pixels away).

I'm decent in GML, so i should be able to follow any reply given.

Hmm...how would you do this with one object and the mouse? Since the cursor pretty much moves along when the view changes, so it goes crazy.

[daman123125]

You can just edit the script:

view_hview[argument1]=(distance_to_object(argument0)*1.5)+150
view_wview[argument1]=(distance_to_object(argument0)*2)+180
view_xview[argument1]=((x+argument0.x)/2)-(view_wview[0]/2)
view_yview[argument1]=((y+argument0.y)/2)-(view_hview[0]/2)

To this:

view_hview[argument1]=(distance_to_point(mouse_x,mouse_y)*1.5)+150
view_wview[argument1]=(distance_to_point(mouse_x,mouse_y)*2)+180
view_xview[argument1]=((x+mouse_x)/2)-(view_wview[0]/2)
view_yview[argument1]=((y+mouse_y)/2)-(view_hview[0]/2)

[piedude04]

I still get the problem: it still goes crazy. Since the cursor changes position in the room as the view changes size, the view would keep getting bigger or smaller even when the user isn't moving the mouse.

[daman123125]

Try using window_set_mouse to change the position.
I'm not sure how you would do it though.

[chocoblock]

I really like how this works its a very nice and easy to implement.

[digidog08]

I solved my problem. I edited to where i created an invisible object that turns into a "zoom in object"
SO like, if you are moving towards an area (such as a hill) It will zoom in as you approach it, and zoom out as you leave it.

[capitankl]

thanks so much I have made a 4 players race but I hope this can work very googd your example, I understand everything Thanks!!!

[Strickendead]

view_xview[argument1]=((x+argument0.x)/2)-(view_wview[0]/2)//sets the x position of the view
view_yview[argument1]=((y+argument0.y)/2)-(view_hview[0]/2)// sets the y position of the view

In the last part of these two lines "(view_hview[0]/2)", is there a reason you used 0 on this one or should it be argument1? "(view_hview[argument1]/2)"

Edited by Strickendead, 20 January 2010 - 09:51 PM.

[daman123125]

It doesn't exactly matter, since there is only one view.
You probably wouldn't need multiple views, unless in the rare case you do, argument1 is there.
argument1 is just what view you are using, and goes from 0 to 7.

[Braden]

if anyones interested im in the process of making one that uses a ds list for the objects to follow
so you can add an object to the list and the camera will adjust to follow more then 2 objects

for now heres a mod to the script to keep it within the bounds of the room size, enjoy

view_wview[argument1]=min(view_wport[argument1],max(distance_to_object(argument0)*2,view_wport[argument1]/2)); // sets the width of the view
view_hview[argument1]=min(view_hport[argument1],max(distance_to_object(argument0)*2,view_hport[argument1]/2)); // sets the height of the view
view_xview[argument1]=((x+argument0.x)/2)-(view_wview[argument1]/2) // sets the x position of the view
view_yview[argument1]=((y+argument0.y)/2)-(view_hview[argument1]/2) // sets the y position of the view

// keep view within bounds of room
if view_xview[argument1]+view_wview[argument1]>room_width {view_xview[argument1]=room_width-view_wview[argument1];}
if view_yview[argument1]+view_hview[argument1]>room_height {view_yview[argument1]=room_height-view_hview[argument1];}
if view_xview[argument1]<0 {view_xview[argument1]=0;}
if view_yview[argument1]<0 {view_yview[argument1]=0;}

<shameless plug> when i get the new camera script working it will be in my TDS [see sig] </ shamless plug>
