This might be an old topic, but it's the only one about 'two object views'.

I didn't like the current one so I editted it a lot.
And now I cannot help myself posting my version up here...

I made my script compatible with every kind of aspect ratio.
It doesn't matter what the room width and height are, this will work.

I've also declared a couple of new variables so the script doesn't look difficult.
Don't pay attention to them. And don't pay attention to anything beneath it.
Just pay attention to the variables minzoom and maxzoom.
Oh, and change objects player1 and player2 to what you like.

minzoom=1                           // sets the minimal zoom
maxzoom=2.5                         // sets the maximal zoom

min_wview=room_width/maxzoom        // sets the minimal width of the view
min_hview=room_height/maxzoom       // sets the minimal height of the view
max_wview=room_width/minzoom        // sets the maximal width of the view
max_hview=room_height/minzoom       // sets the maximal height of the view

// calculates the size and position of the view

xdistance=point_distance(player1.x,0,player2.x,0)
ydistance=point_distance(0,player1.y,0,player2.y)

if xdistance/room_width>ydistance/room_height {
    view_wview[0]=xdistance+room_width/4
    if view_wview[0]<min_wview {view_wview[0]=min_wview}
    if view_wview[0]>max_wview {view_wview[0]=max_wview}
    view_hview[0]=view_wview[0]/room_width*room_height
}
else {
    view_hview[0]=ydistance+room_height/4
    if view_hview[0]<min_hview {view_hview[0]=min_hview}
    if view_hview[0]>max_hview {view_hview[0]=max_hview}
    view_wview[0]=view_hview[0]/room_height*room_width
}

view_xview[0]=(player1.x+player2.x)/2-view_wview[0]/2
view_yview[0]=(player1.y+player2.y)/2-view_hview[0]/2

// keeps the view inside the room

if view_xview[0]+view_wview[0]>room_width {
    view_xview[0]=room_width-view_wview[0]
}

if view_yview[0]+view_hview[0]>room_height {
    view_yview[0]=room_height-view_hview[0]
}

if view_xview[0]<0 {
    view_xview[0]=0
}

if view_yview[0]<0 {
    view_yview[0]=0
}

You are a genius, thank you!

Pretty flashy, but it zooms in way too much. It needs a limiter or something of the kind.
Overall the example was smooth and worked well!

why like this?

[ironmaneleven]

I am making a 2D multiplayer game with 2 players and I want it to zoom out when they get further away from each other, but I also don't
want it to zoom in too far when they are close to each other. How should I alter this script to function this way? Please help

Thankyou for this code, but how do I apply to my code. sorry I am very new to adding scripts into my game.
