Help with passage eventing! - StormOfSouls - 06-25-2010

So I am currently working on a part of my game in a cave in the desert, so I am using the default "Cave of Earth" tileset. Using this, on any given cave map I have put the "light" tiles to evidence where you came from at the bottom of the map, and regular cave entrance tiles to use as passages., as shown in this pic:

http://i725.photobucket.com/albums/ww257/StormOfSouls/forumhelppic.jpg?t=1277435835

Going forward has been no problem.
What I have been unable to do, however, is create an event at the bottom of the map that takes you to the previous map by simply being in the light at the bottom of the screen and pressing down, essentially "going through" the passage. Is it possible to do this WITHOUT altering the map?

So I think I finally figured it out. It works to an extent, which I am happy with for now. If anyone wants to see what I came up with I'll be happy to post it.

But I do have another, non-related question if anyone could help me out. I want to create an item that works in scope on both an hp 0 ally and an ally regularly. However I can only seem to get it to be one or the other. Is there a solution to this?

NO! THAT IS NOT POSSIBLE AT ALL!

Just joking around, while it is not possible by default, I made you a script for it.

Here is what you need to do:

Go to the script editor in your game, create a new script above main and past the script above.

Now, to make an item have the scope you requested, make it's name end with %.

So for example, if you want an item called "Potion" to be like you requested, change it's name to "Potion%". The "%" will not be shown in the game, it is visible only in the editor ;)

Wow! Thank you so much, it works just fine!

Obviously I am a bit new to RMXP, so the help is appreciated. I might get into learning the scripting language later, if I get more time, but for now I'm just concentrating on making a good game.

Just curious, how long did it take you to "make" that script?


Help with passage eventing! - deValdr - 06-30-2010

Half an hour ;)
No need to hurry about learning to script, there are plenty of scripts on rpg maker sites like this that you can use.
Why don't you post some info about your game in the projects section? :)


Help with passage eventing! - StormOfSouls - 06-30-2010

Okay, well thank you very much!
I'll probably get around to posting info later too... :)

There is one more thing I've been searching for, and I don't feel like making a new thread... and that is either one of two things:
1. A way to trigger an event based off of a certain character leveling up. I want to create a way for players to choose their skills as they level, and so I think if an event could be triggered on level up to bring up a menu of sorts for them to do this, that would be awesome.
2. A way to create the aforementioned menu, and have access to it through the touch of a button. (Like the "Press A for email" program in the sample game - KNight Blade).

Could you or someone else point me in the right direction?

Sort of, though not exactly. The idea of accessing said skill menu from the menu is good, I'll want that.
However,correct me if I am wrong, but that system needs to link equipment to the skills you are learning, as that does not seem necessary. More of what I want is a system that goes more like:
1. Player Character attains level in which they learn a new skill. (Example, a elemental mage)
2. The player goes to a skill menu or tree. From there they have a few choices of what to learn. (Example: choice of earth skill, fire skill, water skill, air skill)
3. They choose which skill they want, which opens up further options for further levels. (Ex: choose earth skill, get the option next skill level to gain a more advanced earth skill, while retaining the abilities to learn the fire, air, water, etc)
If there is a way to do this with the aforementioned system, please let me know!!

Also I have seen this system, and am thinking of using it, just for skills -

I think it might work for my purposes, we will see though. It's a lot of extra eventing, and I would almost prefer a menu system instead. But hey, i'll use what I can find, eh? :)

That looks good. You should use a common event for the triggering.

Here is a demo. You'll have to change/modify it to your liking though.
