The RPG Maker Resource Kit

• <Version 1.0> 04.05.2010 - Original Release

---

This script allows the player to take a screenshot of any area in the game that he/she wants. Useful for sharing achievements I suppose. I made it for my own nefarious purposes and without thinking whether it would have any real purpose in an actual RM game.

• Allows the player to take a screenshot at any time by pressing the button of your choice.
• You can set where the pictures are saved and what preface they have
• You can force take a screenshot at any time through a simple script line, $scene.take_screenshot

Please see the header. It's very simple.

Please post in this topic at RMRK for support.


No currently known compatibility issues. The script will be unable to take screenshots in any custom script that makes a scene that does not inherit the update method from Scene_Base however.

this is badass and way more useful than you think. is there a way to take a screenshot of areas of the map that aren't within the window of VX? Specifically, can you make this puppy screenshot the entire map? If you dig through our guild game, you'll notice an XP version of what i'm talking about. We're using it to build our maps in XP, screenshot the whole map, use the image as a background image in VX and build the game on top of that from VX. Complex, but very cool effect. Curious if this could do the same, but for VX.

No, it can't take a screenshot of a whole map. Probably wouldn't be too hard to do though, if you want me to.

Modern Algebra, I love you. This is, as grafikal stated, a badass script. :3

That would be amazing. If you'd do that, i'd love you more. I don't know how i could do that though. Maybe i'll find a way to get roph to send you nudies.

Hm, looks like I won't have to: Omegas7 wrote a script to save the map as a picture, so you can send the nudies to him: http://www.rpgmakervx.net/index.php?showtopic=28578

I think he miscredits the PNG Saver script though, unless 66rpg.com is woratana.

Whoa awesome. Maybe he updated the credits? It looks like Wortana is credited for the PNC Saver Script. Very cool :D

Yeah, the author of the PNG Saver is 66rpg.com I think, not Woratana.

ooohhh ok, I thought you had meant the other way around. Well if I get around to use it, I'll have to delve in and check it out.

I have a question could you this with a save screen script that shows a picture to show where you are and if I can how would i do it

I can't change destination folder, it saves images to in project folder but I want it save them in graphics\pictures\. :C (sorry for my bad English)

Wow, tried Graphics/Pictures/SS rather than Graphics\Pictures\SS and it is working. Great script, thank you very much... XD

There is a edit button you are not supposed to double post.

There is a 'report' button too. You're not supposed to back-seat moderate!    ;D

<Scratches head> Hmmm, I always thought SephirothSpawn wrote the screenshot.dll ???
