Fit to Browser Window


Designed for browser deployed games, this automatically fits the game screen to the width and height of the client's browser window.


Plug and play, though it is up to you to create appropriately sized maps and graphics, and to understand how and why this script should or should not be used.

The creator can specify a maximum size and minimum size for their game; the game will not go beyond these boundaries. Leave blank or 0 and the game will just fill the available space.

When testing this plugin please note that the size of the game's title screen and first map are for a small screen, so you won't initially notice that the plugin is working! As I said it is up to you to tailor your game to the plugin.


Credit to YanFly for a few lines from the resolution changing script. I have just plugged my own variables into these lines.


I am not used to releasing my plugins publicly so I apologise if I have broken any unwritten rules in my plugin; I've tried to keep to the standards set in the plugins I've seen.

I want to do a new version eventually which will resize the game when the client resizes their browser window, but I am not sure if this is possible. Currently the player will have to reload the game if they change their window size.

The plugin has no benefit whatsoever to a standalone release.

My first game is going to have the main character more or less create monsters as his party members.

Thanks to the plugin creators still producing content for MV, I might be able to give each of the monster members a personalized range of tactics during combat. I liked how the devs made it like that in FF6.
Stream will be live shortly! Tonight will be the PREMIERE of Killer 7 for the first half of the stream, and at half-stream, we will switch to a session of the Interactive Text Adventure! Feel free to drop by!
Watching the launch, I felt a sort of detached excitement. Usually I'd think something like this would be extremely exciting. I'm fascinated by space exploration and am a big Sci-Fi fan. I guess it's just current events.
What did everyone else think about it?
Doing ep 1 of my RPG!
For those still craving more Konosuba madness
I'm new here, any tips welcome

Hope you fun! :LZSgrin: :LZSkiss:
I set my goal to be finished with Knight Bewitched 2 by sometime in July. Based on my current work schedule and progress, I'm not sure that's going to happen, but by golly I'm gonna try!
