MV - MV + MZ Make an Action Game! Chrono Engine Advanced Features and Scripts (gamepad, status effects, fighting followers)!

AquaEcho · 2024-04-27T02:14:46+0900

Following up from my Chrono Engine beginner guide, I bring you an advanced features guide! I have a lot of Chrono Engine scripts I've written over the past year so I will be organizing them here, and regularly adding new ones. Feel free to share your own! How to add controller support to Chrono Engine: By default the following gamepad buttons are mapped in the engine: Code: Input.gamepadMapper = { 0: 'ok', // A 1: 'cancel', // B 2: 'shift', // X 3: 'menu', // Y 4: 'pageup', // LB 5: 'pagedown', // RB 12: 'up', // D-pad up 13: 'down', // D-pad down 14: 'left', // D-pad left 15: 'right', // D-pad right }; In the Chrono Engine plugin settings it's simple enough to assign or change buttons among the default keys METHOD 1 To add the missing controller buttons (Start/Select, LT/RT), or overwrite those buttons, or if you want to add new keyboard keys, create a new plugin file (create a new file in a text editor like Notepad and save it as a .js file. You can name this file whatever you want because it has no parameters. Paste the following code in it and add the plugin to your project after Chrono Engine. Code: Game_Temp.prototype.loadInput = function() { //keyboard Input.keyMapper[65] = 'item';//A key Input.keyMapper[67] = 'c';//C key Input.keyMapper[68] = 'shield';//D key Input.keyMapper[83] = 'skill';//S key //gamepad Input.gamepadMapper[0] = 'ok'; //A Input.gamepadMapper[1] = 'cancel'; //B Input.gamepadMapper[2] = 'skill'; // X Input.gamepadMapper[3] = 'item'; // Y Input.gamepadMapper[4] = 'pageup'; //LB Input.gamepadMapper[5] = 'pagedown'; //RB Input.gamepadMapper[6] = 'lt';//LT Input.gamepadMapper[7] = 'shield';//RT Input.gamepadMapper[8] = 'start';//start Input.gamepadMapper[9] = 'select';//select }; You will need to edit what's in the ' ' quotation marks of each key to what you want it to do, and update the plugin parameters in Chrono Engine to refer to that command instead of the button/key name. This is because Chrono Engine can only take one reference at a time in those plugin parameters, and 'a', 'b' , 'x' and 'y' mean different things for the keyboard and gamepad. If you want to add keyboard keys, you need the key's keycode number. To get the keycode use this link Then add it in the Input.keyMapper[x] section above As you can see in the Chrono Engine plugin settings below I have the Shield button set to 'shield'. In the plugin we just made we have the D keyboard key and RT gamepad key set to 'shield' so pressing either of those will use the shield in game. Rebinding keys during the game: You can remap keys or buttons during the game using the script calls for a key or gamepad button. For example, if I want to remap the S key to the use an item I just redeclare it in a script call. Running these scripts during gameplay will only apply the rebind for the current gameplay session, you will have to reapply it every time the game is loaded. Input.keyMapper[83] = 'item';//S key If I want to set the X gamepad button to item Input.gamepadMapper[2] = 'item'; // X gamepad button Spoiler: Method 2 (Old) Note: This is an old method that had issues with registering a button being held down (e.g. the shield) I use, Hakuen Studio Button Common Events because it offers support for all the buttons on common controllers. The list of scripts you'll need is: Use item: $gamePlayer.commandRasItem() Use weapon: $gamePlayer.commandRasWeapon() Use skill: $gamePlayer.commandRasSkill() Use shield (note: doesn't work in a common event, you need to redirect the button if it's RT/LT/Start/Select): $gamePlayer.battler()._ras.guard.active = true; $gamePlayer.updateGuardDirection(); Skill menu: $gamePlayer.commandToolMenuSkill() Item menu: $gamePlayer.commandToolMenuItem() Main menu: SceneManager.push(Scene_Menu) Create a common event for each button. Name it after the button, then put in the script for what you want the button to do. Go to the plugin settings for Eli Button Common Events and add your buttons That's it! Plug in your controller, then start a new playtest. It may not work if you plug it in after you start the game. Also, make sure you are testing from a new game and not a save file as plugin settings may not take effect on a save file. An additional script that someone requested to make dashing share the 'Ok' button. This overwrites an engine method so you need to copy and paste it in .js file and add it as a plugin to your project. Code: //Make Dashing share the ok button Game_Player.prototype.isDashButtonPressed = function() { var shift = Input.isPressed('ok'); if (ConfigManager.alwaysDash) { return !shift; } else { return shift; } }; HP Bars over the Enemies! RPG Maker MV + MZ Chrono Engine HP Bars over Map Enemies by AquaEcho A mod to MOG_EventIndicators to allow Chrono Engine to show HP bars above Enemies aquaecho.itch.io Make status effects work in ABS mode (also see Yanfly Buffs and States Core patch below): By default status effects don't work in ABS mode because they use turns and turns don't happen in ABS mod…

Hello, I want to add something. It's known how to make status effects, but when you have more than one state at the same time (Let's say poison and bleed) they both check the turn count, making both states end twice as fast. And I figured out a way to make several at the same time work fine. Should I post it here?
The parallel event checks every state. You should not be using that block of code more than once. If you have another state that can do damage, or recover it, you copy and paste the line checking for the poison state that many times and then just change what number state you're checking and the percentage life damge it does.

A question: In Chrono engine, by default, events are only able to spot the player by proximity, not sight. There is a way to make an enemy activate and begin to attack the player on sight?

If you are using Cross Engine use Dahlys Distance Calculator which has vision cones. I gave scripts and examples on how to use it in my Fighting Followers post.

I don't understand it very well. I don't use followers, so how could I make it to the enemy noticing the player, attacking the player, and then leave the player alone if the player goes too far?

Code:
if(Dahlys.distCalc.canSee(this._eventId,-1)){this.setSelf('D', true);}
That will make it so if the enemy sees the player, it will toggle its self switch D.
Code:
if(Dahlys.distCalc.distance(this._eventId, -1) >256){this.setSelf('D', false);}
If the distance between this event and the player is more than 256 pixels turn off self switch D.
Code:
if(Dahlys.distCalc.distance(this._eventId, -1) >128){this.tLoc($gamePlayer.x,$gamePlayer.y);}else{this.turnTowardCharacter($gamePlayer);this.act(73);}
If the distance is greater than 128 pixels (but less than 256 pixels), move toward the player, else turn toward the player and attack with tool 73.

I'm using the first two codes in the enemy and is not working. Is not activating the Self Switch D.

You need to be using Dahlys Distance Calculator and Cross Engine

Yes, I'm using both. I tried the third code in a moment and it worked.

Does the enemy or the player have a custom collider? Could you delete any custom collider and see if that fixes the issue? Also place Dahlys Distance Calculator right under Altimit in your plugin list.

Ok, I think the Issue was that I placed the plugin in a wrong place. And how I would make it that the enemy can't see the player if he or she is behind a wall.

You make the wall a certain region ID or terrain tag and set it in the plugin parameters

Ok, Thank you. Now I have it like I want. I guess the enemy lose aggro when you leave it's vision cone? Or how it lose aggro exactly?

I have a new xbox controller and i managed it to partially work fine with Chrono Engine but I get this error everytime I press RB button. I used the plugin code for gamepad mapping and key mappings. How can i remove this bug?

If it's only happening with the RB button and none of the others then something is wrong with the line of code where you assigned the RB button

Is there a way I can make the follower have different pattern attacks depending on equiped weapon?

You'd edit the common event where the follower's attack and movement pattern are stored to have conditional sections where you check that party member's equipped weapon
