Explosions

Do you wish to spring an explosive trap on your players,? of course you do. For this tutorial you need the following modules:

• Monks Active Tiles
• Sequencer
• JB2A -- Animations

Step 1 -- Some groundwork

First we need an actor that can perform the trap attack. Create a new NPC, name it traps and give it a fitting icon. The NPC also needs to have an attack action, call this action "Explosion"

Next head over to freesound and download a suitable sound file for the explosion. In the macro below, we need the file to be placed under "media/156031__iwiploppenisse__explosion.mp3", replace this with your selection of sound.

Step 2 -- A Sequencer Macro

Click the token-bar or create a new macro from the macro menu. Call this macro "Explode At Tokens". It should contain this:

let targets = arguments[0].tokens;

let sequence = new Sequence()
for(let target of targets){
    sequence.effect()
        .atLocation(target)
        .file("jb2a.explosion.01.orange")
        .sound("media/156031__iwiploppenisse__explosion.mp3")
       ;
}

Make sure you remember set its Type over to script

Step 3 -- Configuring the Active Tile as the Trap trigger

Create a tile that spans the entire area where the trap should be triggered. In my case I used a fitting image spanning only one grid-cell. Remember to hide this image, so that your players can't easily see the trap.

Double click the tile to bring up its configuration, and move over to the "Triggers" tab.

1. Set the tile to trigger "On Enter"
2. Add the "Run Macro" action, and set it to run the macro we created in step 2.
3. Add the "Attack" action, select our Trap actor, and the "Explosion" attack.

And, thats all.
