Mode7 VX Options

Mode7 VX
From 2chan

Introduction

Adds 3D like functionality while riding an Airship.

Screenshots



How To Use

Plug and Play. Place the scripts in the demo above 'Main, but you have to import the 'bg.png' file included in the demo to your project's 'Graphic/Pictures' folder.

To activate mode7 anywhere on the map, make a call script command with this '$game_map.mode3D = true'.

Read my post here on how to change the angle of incidence (lolwut).

Demo

Compatibility/Known Bugs
-Any other visible events (those with graphics) will offset in the map while in Mode7.

Credit and Thanks
-RGSS2 scripters at 2chan for letting me post this.

Author's Notes
This is a basic Mode7 script. Unlike it XP counterparts (Neo Mode7, among others), it doesn't include rotation/zoom/tilt/ functions.

And also,

I suck at scripting.

i actually was looking for a script like this I will be using it and give credit to you, now i just need my game to work

[Silverelick]

1 you need the Image from the Demo 2 I was looking for something like this http://www.youtube.com/watch?v=6RRF5KGseek
.

1.I don't comprehend what you are saying. Really.

2.I believe for that, you have to specify terrain tags for tilesets for objects to drawn verticaly (i.e not rendered into the map). Unfortunately VX doesnt support terrain tags (no wait, i think it is, via scripts, but like i said, this is a basic Mode7 script).

Actually, the objects stick up because they're events. If they were simply added as a layer on the map, they'd be as flat as the maps themselves. Hope this clears things up.

No, im certain the Mode7 in the video uses terrain tags. I have a copy of it. Actually, you can use events in this script to make it 'stick out.

Like this:



But if you walk around with it...



This script doesnt apply depth for events.

[miget man12]

Would it be possible to make it so a certain map uses mode7 while walking? instead of just an airship...? Other that that, great script! Does credit go to you? if not, who?

[Chronno]

you could make a event in with a call script with this code: $game_map.mode3D = true
that maybe works

Do credit '2chan RGSS2 Scripters' but of course it would be nice if you also credit me.

Correct.

Anyone know how to change how much the surface curves? It'd be really nice to know.

In TIleSprite, go to line 287 and you'll find this.

CODE

$game_map.set_angle(90 - (45 / 8 * (@altitude / 4 + 1)))

Change the value 45 to 90 - the angle you want, for instance i want an angle of 70 that would be 90-70 = 20

hence,

CODE

$game_map.set_angle(90 - (20 / 8 * (@altitude / 4 + 1)))

Another change, go to line 293.

CODE

@altitude == MAX_ALTITUDE ? $game_map.set_angle(45): set_angle

Change the $game_map.set_angle value it to the angle you want i.e 70.

hence,

CODE

@altitude == MAX_ALTITUDE ? $game_map.set_angle(70): set_angle

Can I publish this script in other forums?

[PhantomH]

Thanks pain . I'll be sure to credit you for the help.

Can I publish this script in other forums?

You'll need to get permission from the original scripters. There's a link to their site in the credits.

EDIT: Hm, your instructions only works for the airship. I was hoping we could get one for walking since my game won't be using airships :| .

[miget man12]

For walking with the Mode7 effect refer to Chronno's Post:

you could make a event in with a call script with this code: $game_map.mode3D = true
that maybe works

Thanks Chronno!

Feel welcome to post to other forums, But do give credit to 1. 2chan RGSS2 Scripters and 2. Painhurt.

[chorrol]

Really cool script, i WILL use this in my game!

[Genshyu]

Hmm, if only you could make this where you could walk around like this, that would be Freakin sweet.

[Dusk noun]

Well it's a very requested for VX script. But it needs to be emproved

And you CAN make it work always but i'm not agree with the method. Yes, if you make a script call with "$game_map.mode3D = true" it turns on, but once you get on an airship, the angle sets again so you a return to 2-D and then again to conic perspective. And once you get off, the variable turns to false, so it turns off (not when you get off an airship, actually, it's when the altitude is 0 but it has the same effect). A scripter can solve that but here there are people that don't want to edit the scripts or don't know how to edit them. So to make that way work ever. you need that code to be updated everytime you get off an airship. To avoid that i've made an "alternative" TileSprite script taking out those effects. So if you want the game to be always in conic perspective, replace the whole code of the TileSprite script with this one.

NOTE FOR THE SCRIPTERS WHO WATCH THIS CODE: If you think i've done something wrong or i removed a critical proccess it shouldn't been removed, instead of complaining polite or impolitely, try to emprove it yourselves. And you should know this is a fix i improvised in 5 minutes, it makes the conic prespective always on and disables the airships changes on the angle and the critical variable. It works without bugs at least on my PC.

But the script has another problem apart from that. The objects (events) aren't fully synchronised with the map so sometimes when you walk, the events end being in the space (the background on the backside). This must be fixed but i can't request to the scripters (everytime i search it in 2chan i end in pages with erotic content), and i can't make it on my own (my scripting skills are great for windows but i don't know much about spriteset) so i let it on the air, if someone read this, maybe that one can fix it.

[PhantomH]

Someone should also fix the autotile problem as well for those who're using it in towns and/or cities. I was testing this script on one of my maps and then when the game is in Mode7, the roof for a house would either disappear or cover the walls until I go back to plain view. It would also be nice to somehow modify this script so it can use KGC's Tileset tool but we should worry about the first two issues first.

[Ziosin]

This script is freaking cool! I used it in the demo and feel in love with it .

Thanks for bringing it over here!
