CROSS ENGINE: Combining Chrono Engine with Altimit Movement

Restart · 2020-06-09T14:38:33+0900

Latest Version: Cross Engine Alpha 0.20.06.26 Demo Project What is Cross Engine? Over the course of the last few months I've been working on my game, and I decided I wanted to combine Altimit Movement and Mog's Chrono Engine. Cross Engine is what I call the big pile of functions that makes both of them work together, giving both pixel movement and ABS mode. It also includes bugfixes, and QoL features that came up when I was doing things (most of my notes to self thread is included). Basically, this is all stuff I found useful, and hope that other people will find useful as well. Why's it called Cross Engine? Partially because it's a Cross-Compatible Engine for making games, but mostly because it's a followup to a beloved classic which killed off Chrono. Compatibility Patches Cross Engine now works with yanfly's itemcore, altimit movement, yanfly's item spawner, yanfly's doodads, and galv's camera plugin (the last of which is actually essential to avoiding event/doodad jitter). Also, Ultra Mode 7. Spoiler: Other New Features: 8-directional, 2 directional, and 1-directional Spritesheets: Sure, a lot of people have 8-directional spritesheets (and I support all the major formats), but how many people have ONE-directional spritesheets? With Cross Engine, you can take any old image, give it a filename, and put it in. Save it as $Angel(f1)(d1).png, and BAM, it's usable as an event. No mucking around in photoshop making a spritesheet with four versions of the same sprite. But that's not all! I also added intelligent sprite flipping, as well. If you named that angel $Angel(f1)(d-1).png instead, it will flip to face left if it moves left, and flip to face right if it moves right. Split poses and actions One of the things really dragging down the pace of a chrono engine game is that characters were locked in place while they animated. I have changed the engine so now you have a separate 'pose duration' and 'act duration'. Pose duration means your character is playing an animation, act duration means they can't move or cast anything. I've also added a 'cooldown duration', which lets you move, but doesn't let you cast any abilities. Intelligent Tag Parsing 1) Tags parse from right-to-left, instead of left-to-right. This seems super minor, but it means that if your base character sprite is $Harold(f4)(d8), and he has a casting pose "_casting(f8)(d1)", then the new spritesheet sizes will take precedence! 2) Filename Completion: Let's say your idle sprite for harold is "$Harold(f4)(d8)_idle(f1)(d1)". In base Chrono engine this would cause rpgmaker to screech to a halt, because it can't find "$Harold(f4)(d8)_idle". However, upon starting up the game, Cross Engine makes a list of every file in your characters folder. When it checks for poses, it will first check for an exact match. If it doesn't get it, it will check to see if there's any longer versions of that filename. If it checks for "$Harold(f4)(d8)_idle", and can't find it, it will return "$Harold(f4)(d8)_idle(f1)(d1)". What if there's no match at all? The event keeps its base sprite. In playtesting, it will whine about it in the console. No crashing. 3) Negative values are now allowed for x and y offsets. Walking actions You know how in megaman you can shoot your little gun and megaman keeps on walking? Using the tag (walking) will keep your character in the same part of the animation cycle when transitioning into the new pose. Practically speaking, that means you can do the megaman things. If the character isn't moving, it will fall back onto a _static pose, so you don't run in place whenever you shoot. Standing Pose One of the big constraints on having fluid animation in rmmv is that your walking frames have to include a static pose used for standing. If you define a 'standing' pose, your character will use that instead when they aren't moving. While you can technically do this with an idle pose, I wanted to have both in my project. Faint Poses Mog was going to implement faint/death poses distinct from damage poses, but didn't end up finishing it. I have an implementation of this, so you can have a robot get banged up a bit when it gets hit, then violently explode into a miserable pile of circuits when it dies. Basic Preloader Function One thing you'll notice using chrono engine is that whenever creatures change poses for the first time, you'll sometimes see a flicker as the file loads. I have added a function which preloads all poses for a creature. If you enter ImageManager.preloadPoses('Ralph'), it will find 'Ralph_attack', 'Ralph_defense', 'Ralph_is_unstoppable(F4)(d8)(s2)(x4)', et cetera, and preload them. This doesn't happen automatically - you have to invoke it each time you're worried about preloading. New plugin command: disable_idleposes Turns off idle poses. Good for cutscenes where characters mugging at the camera is unwanted. Turn them back on with enable_idleposes Intelligent Rotations Do you want a magic circle of spinning runes? I've got you covered…

Hello, I was playing/testing with the plugin but there's something wrong with the sprite image

I don't know why the box only fill that small portion

and the result when testing the game is like this

why is that, and how to fix something like this ?
and I don't change anything from the plugins demo

Hey there, I recently tried using this plugin and it stops Yanfly's Region restrictions and region events plugin. It also stops Mog's weather plugin. I've rearranged the plugins and it just causes more glitches. Is there a way around this? I've also noticed the download for the file comes with Mog's character poses plugin turned off which causes graphical glitches, there's another thread looking for a solution to this, but it is old.

Try going into the plugins settings and turning on MOG's Character poses. It seems it was turned off in when it came with the download by accident.

Hi there!

Thanks for your work,
my game with the cross engine run well on desktop but when I tried to play it on web/html it doesn't work and show "require is not define"

It worked when it was only chrono engine but doesn't with cross engine, and to be sure I try to upload only the demo without any modification and the same problem here

Can you help me please ?

Thanks again for this!

This line seems to be the problem

I tried to change it to this

var fs = require? ("fs");

And it work i can launch the game but animations of fight like sword are junky and doesnt work well

sounds like it's searching image files on computer so it works on desktop but not on html or android...

Any idea how to fix that ? anyone already made a game for browser or mobile using crossengine ?
thanks again

Hello there!

I too have tried to upgrade my existing project from Chrono Engine to Cross Engine and it didn’t work out well. Some of the features that were supposed to be upgraded in the updated engine did not work. The Cross Engine play test also had some issues, I believe the author incorrectly named some files which messed up animations.
Overall Cross Engine butchered my project and I was disappointed because it has great features. You may have to revert to Chrono Engine like I did, also keep a backup of your project before Cross Engine so it doesn’t break your game.

The ._inMotion fix works for the player but not for events. Is this intentional and is there any way to detect if an event is moving (since .isMoving() doesn't work either)?

Works: $gamePlayer._inMotion
Doesn't work: this._inMotion, this.character(0)._inMotion, $gameMap.event(id)._inMotion

Edit: Finally figured it out. I had the block of code in CrossEngine.js and it doesn't work there for some reason. I had to create a Conditional Branch on the event page with Script:
this.character(0)._inMotion

and this block of code had to go at the end of rpg_objects.js

Code:

var Game_CharacterBase_update_for_ismoving = Game_CharacterBase.prototype.update;
  Game_CharacterBase.prototype.update = function() {
    //.isMoving doesn't really work in altimit
    //this fixes it with the addition of a new function which I can use to tell
    //if the character is actually like, moving
    // the problem seems to be that the isMoving gets cleared midway through
    // this update step (because the .updateMove in rpg_objects sets ._realX to equal .x)
    // but lots of things break if I monkey around with _isMoving
    // so I'm creating my own clone of it here.
    // this is true if the character is in motion and false if they aren't.
    if (this.isMoving())
    {
      this._inMotion=true;
    }else{
      this._inMotion=false;
    }
    
  Game_CharacterBase_update_for_ismoving.call( this );
}

Hello! I'm making a game with cross engine and I have some (maybe dumb questions)
How does the hurtboxes work and is it possible to edit them?
From what I noticed the collision box from Altimi movement is different than the hurtbox - if so, can I change how big the hurtbox is for enemies? like change numbers etc?
Thanks in advance!:kaoslp:

For me the only problem was the hookshot, its collision is all buggy, even using the debug I didn't understand why it's buggy. I activate the hookshot forward and it grabs what I don't want it to grab, if anyone knows a solution I'd appreciate it.

In the screenshots below I'm trying to miss the hook on purpose, but it hits the wrong hitbox and pulls my character:LZSteary:

AquaEcho did you try something like this in a conditional branch?

ev = $gameMap.event(this.eventId()); ev.isMoving();

That's what I use to detect my event's movement.

Speaking of which, does this version do anything to fix states like poison on a moving enemy in ABS mode? Or does anyone know a way to combine this event move check with a way to see if that event's enemy has a current state? That way you could manually assign damage by calling a 1 tile radius skill on top of the event. I do that right now to combine GALV's projectiles with MOG's Chrono ABS.

I'll look at this issue later today but poison is probably something I'd use Galv Event Timers for.

Hi! Does anyone know how to set up the new enemy defeated sheets that Restart added as a new feature? I wasn't able to find anything for that in the demo file.

you can make it appear by adding Death(Xframes etc) suffix like in my screen, though before the enemy vanishes you can display 1, max two frames. You can also do a damage sheet that way

thanks! Have you experimented with jump commands at all? Running into an issue where you can jump straight into regions restricted by YEP Region Restriction and YEP Smart Jump because of how Altimit works I assume.

I actually did in the past but i dunno as well, you might try to post in Altimit thread for this though

You'll need to put a conditional check on your jump commands to check for region id of the destination tile and not allow it if it's a restricted region. Altimit just draws borders around impassable tiles, you can jump over them, and Yanfly Region Restrictions won't stop a jump into it either.

This will check region ID of the tile
$gameMap.regionId(x,y)
This will check terrain tag if you want to check terrain instead
$gameMap.terrainTag(x,y)

I wrote this code to check every battler on screen every 60 frames/1 second for status conditions/states/buffs. Put it in a parallel common event. There's a line in there for poison damage (default state 4) to do 10 percent of the battler's max hp every second. Don't forget the Wait 60 frames at the end, otherwise it'll run 60 times a second. To control how long the state lasts you need to go to the MOG_ChronoEngine in the plugin list and change the States Duration value in the parameters.
Code:
for (var i = 0; i < $gameMap._battlersOnScreen.length; i++) { battler = $gameMap._battlersOnScreen[i].battler(); if (!battler.isDead()){ if(battler.isStateAffected(4)){ this.changeHp(battler, -(Math.floor(battler.mhp*.10)), true);} battler.startDamagePopup(); battler.updateStateTurns(); battler.updateBuffTurns(); battler.removeStatesAuto(1); battler.removeStatesAuto(2);}}

Sorry, novice at scripting so I'm sure I'm missing something here, I added the if check as the following:
Code:
$gameMap.regionId(x,y) != 10
and it returns an error: "X is not defined"

EDIT:

Think I got it, I set additional if checks for direction and defined the x and y based on the facing direction and that's working so far. will do some more testing. thank you!

Yes...you need to define what x (and y) are. What are the coordinates you are jumping to? You know, I don't, so I gave you variables to fill in. If it is 5, 6 then you need to put in (5, 6).

Figured it out while you were typing and updated my post, thanks for solving this for me!

EDIT: your method does not work. oh well
