Overworld Gunplay in SciFi RPG

Hey there folks,


I am currently developing a SciFi Rpg in MV and has been having trouble with one of the concepts that I wish to implement to the game. If anyone has ever played Lufia the Legend Returns then they know about the dungeon mechanic of swiping your sword or more importantly using a wave attack. In the game players were able to press the Action button and swipe their sword to reveal secret passages, cut down shrubs to reveal chests and traps.


Holding down the button made the sprite ready a wave animation that would send a particle effect in a straight line in the direction that the player was currently facing. Any monster that was hit by this wave animation effect was stunned for a small amount of time. The wave would also cut down any shrubs in its path, and open hidden passages if it struck textured walls. Here is an example:

Anywho I would love to try and implement this game mechanic into my game. My idea is that the player can hit an enemy with a close ranged melee strike in the overworld, that would trigger a preemptive battle. The player could also hold the action button (or another key like "F") to do a slower, yet ranged attack that would hit an enemy event and also trigger a preemptive strike. 


I'm currently using Yanfly's Region plugins and the Stealth Plugin so that enemies when spotting the player will either trigger a battle screen automatically (ranged Human enemies) or cause the enemy to chase the player for a melee strike (melee creatures or humans). Having this other mechanic would allow the player to gain a chance to control when battles happened.


Imagine a player in a corridor and they see an enemy coming toward them. They hold down the action button and prepare to take a pot shot at the enemy sprite, when all of a sudden another enemy comes out of a door and spots the player first. A battle is triggered, but now instead of a single enemy, the player  has to deal with two enemies that now have the upper hand!


What do you folks think? Is this possible using Region controls or would it require more extensive events and Java Scripting? Anywho, thank you for your time!

 

I can't really say anything about the plugins but it should be possible with events at first glance.


Not exactly going to be easy by any mean, but it's possible if you can handle some advanced level eventing.

 

It's possible to do this. Problem is, RPG Maker's event collision detection is really basic. Event creation is also very basic.


There's plugins that expand on the basic event interactions used by the RPG Maker engine.


The level of difficulty, if evented, is around the intermediate-expert level. And it would require javascript commands to be used in the eventing. Using plugins it gets a lot easier, depending on the plugin used.

 

I figured it would have to be done with a common event. I would assume that I can find a plugin in the master plugin list? I'm currently learning javascript and am up to the challenge. How can I access the Java Script for the MV program? I probably don't want to mess around too much with it, I imagine that it would quickly crash the software.

 

Some detail questions:


1.


How many Enemies maximum per Map?(Enemies, slayable Bushes counted together)


2.


If you make a Sword slash, in which distance do enemies get hit? 1Maptile infront of Player or more?


If more tiles, do all enemies get hit by that blow or just 1 of them?


3.


Can the Energy Wave atack shoot through Walls or does it need, to not going through walls?


4.


Does only one enemy get hit by energy wave atack or all enemies in a line?


My English aint always the best but this would be interesting to know for me.

 

1. I'm thinking 10 max to start. 


2.The sword slash (or in the case of having a gun equipped, a gun bash), would only affect one map-tile in front of the player. Holding the button for the wave attack would affect multiple tiles depending on the gun type equipped (Shotgun=2, Pistol =3, Repeater/Cannon = 4, Rifle = 5). Just one would get hit, but it would trigger a battle for all of the mobs next to them. In my first map I have three mobs grouped together, conversing. You hit one with a rifle shot or bash and it would trigger a battle with all three as enemies in a single troop. One of the enemies would be heavily injured because you triggered the battle this way. Win the battle and the three mobs would disappear.


3. The energy shot would not be able to go through walls.


4. It would only hit one enemy.

 

Find your game's folder in Windows.  Click the "js" folder.  Edit the appropriate file, or open the "plugins" subfolder and write a new .js file that aliases/overwrites/adds methods to the existing code.  Make sure to add your plug-in to the Plugin Manager in the editor and to turn it ON.


I agree that this kind of thing is best done with a script.  Some people mention that hit detection is not so great in RPG Maker, but this kind of thing can be solved with very basic JS skill, since you can check an event's location, direction, etc. and compare it against the player and all other events.

 

it's possible with events. You're just calling your map xy and button presses right? I'll work on this today. I have a game with a similar mechanic...

 

Okay i saw this earlier but had other stuff to do. Now i had some Time and made a little Demo Map.


I just have the Demoversion but  posting the Mapfile here should be enough for you to Test it, right?


-Melee Attack W-Button


-Range Attack Q-Button / Walls get detected


-10Enemies / Bugfree Hitdetection through Screencoordinates


-Uses only standard Editor Commands


-Uses Less than 10Variables


-No FPS Drop on my end on a Windows System, other plattforms i dont own to Test.


Only one possible Way of many to structure this Eventcode, hope its ok to get into this a bit more.


I hope you like it it was kind of like stuff i was experimenting on in the MV Demo, so it helped me too, to get finished/started.


Just Create a New Project and create a MapID 1 if there is non, than close MV and copy the DownloadMapfile and replace the Mapfile in that Project.


In Ace this worked, hope this also works in MV, i hope this File contains all.

Edit: Download removed, new download further down in the thread.

Didn't think of it that way, but yes. Thank you for working on it, I will tinker around with variables and such on my end.

 

Sweet, is there any good editor programs that you can recommend? I'm thinking Ace editor might be a good idea.

 

I use Sublime Text 2, and I've had a pretty good experience with it.

 

..........................................................................Forum Failure at the moment this Post was created........

 

Thank you so much for making this! It looks like it's working fine in MV....the W works but the "Q" brings up an error message of not being able to audio/se/Bowl.ogg. Which I assume is an audio file that I don't have, and wasn't transferred. 

 

Ah ok its just the missing Bow Sound, you should be able to find that in the Eventcode and just delete or replace it.

 

Figured out the sound issue and it works flawlessly. I will tweek the audio and animation bu this is exactly what I'm looking for. Thank you Bex!

 

Sure no Problem, if you have questions about understanding the code i still have 16 Days on the Trial Version and even after that it should be possible to Help.

 

So I'm gathering that the variables really have to do with the player's position? I wonder if I can tie a variable to the gun switch being turned on. Fire your gun too many times and an alarm goes off and enemies will start to chase the player or something.

 

Ok but for that we have to change the structure of the eventcode a little bit so Mechanics can be easier implemented.


I will take a look at it.

 

Sorry for double Post.


I split the Eventcode from 2 to 3 Events, i hope its easier now and the code should be a bit cleaner.


Yes your Question is possible, just count up a variable, i implemented a example just cast fire 5 times and watch what happens.


Edit: Uploaded new Mapfile, first one was buggy.
