I need help with scripts! NECESSARY! IMPORTANT!

[JamesTerrano]

I was looking for a simple vehicle script for a long time.
Today I found this: http://www.universomaker.net/t313-rpg-maker-xp-usar-vehiculos-advance-vehicle-system
This is exactly what I wanted. It's perfect! But there is one problem. In my game I use Caterpillar script. At the beginning of the game is character alone. In this part everything works normally. However, later in the game is more characters. When I try to load a saved game where is more characters in party, the game crashes.
Am I right that it is Caterpillar script that causes problems?
Is it possible to somehow modify the Vehicle Script to be compatible with Caterpillar script (if that's the problem)?

And one more thing. I'm also looking for some Ammo Script. I found some scripts, but some of them were difficult and another didn't work.
I found something I like, but it looks like for RMVX and I use RMXP.
Is it possible to do what is on the screenshots here for RMXP?: http://rmrk.net/index.php?topic=45699.0 (http://rpgmaker.net/media/content/users/96/locker/ammo1.png)

First: I would recommend putting your request as a separate topic to keep the thread organized. Feel free to post requests in the Script Requests board.
Second: What exactly is the error message? No one can help you if we don't know what the problem is. And what caterpillar script are you using? There are a handful of them out there so knowing which exact one you use is also important.

[JamesTerrano]

I apologize for my mistakes.

This is the Caterpillar script that I use.

And this is my problem with the Vehicle Script:


May that Caterpillar script cause these problems? Or is the problem something else?

[G_G]

Try placing your vehicle script below everything else, but above main. According the the caterpillar script, it doesn't even modify Game_Player whatsoever, so it's probably another script causing the issue. Probably, overwriting the initialize method in Game_Player, so your vehicle script can't properly declare the @fdelay variable, hence the "Nil" error popping up.

[JamesTerrano]

This is all scripts that i added to my game. Maybe you'll find cause of that problem in something else. This list of scripts is in the same order as they are placed in the game.

Chaos Project Debug System by Blizzard
AMS - Advanced Message Script - R4 IMPORTANT FOR GAME!
Party Changing System by Leon_Westbrooke
Simple Event Sensor by LiTTleDRAgo IMPORTANT FOR GAME!
Anti Event Lag Script
Caterpillar walking script IMPORTANT FOR GAME!
Dynamic Effects Engine by Ryex
Ryex's Dynamic Sounds
Ryex's Dynamic BABS Monster Sounds
Vehicle Script by albertfish NOT WORKING!
Lagless Path Finder by Blizzard
Path Finding by Near Fantastica
Syn's Ammo Requirements by Synthesize IMPORTANT FOR GAME! NOT WORKING! (Does nothing.)
Timed Choices by KK20 IMPORTANT FOR GAME!
Advance vehicle system 2.0 Falcao script IMPORTANT FOR GAME! NOT WORKING! (Game crashes after loading a saved game.)

Perhaps there is an error in other script than Caterpillar.

[G_G]

For starters, you probably shouldn't have two vehicle scripts in your game. Secondly, I don't see the point in having Ryex's Dynamic BABS Monster Sounds unless you're using Blizz-ABS. If you are using Blizz-ABS, then you have no need for an ammo requirement script because Blizz-ABS already has it implemented. Is this the exact order of the scripts? Maybe you can upload a demo somewhere and we can have a better look.

[Heretic86]

If you can be patient for a while longer, I'll hook you up with a Caterpillar and Vehicle Script, and a Compass Script, and a, oh nevermind.  It may not be the easiest thing to use, but it will suit your needs.



This does work with the Caterpillar just fine, but in order to get the Player in the Boat, I temporarily get rid of the Caterpillar by just making them all jump in the Boat, then fading them out.  It seems to communicate the idea well enough.

Its coming, I promise!  As always, one thing leads to another...
