How to implement when play attack with some weapon then shoot a projectile

[bright steppe]

I used ItemEvents.firstLeftClicked but it will ignore players attack speed.

I don't find a method to get attack cooldown but you can get player's attack speed and do some math to check if the cool down is over.

const MapPlayerLeftClickLastTime = {}
const rechargeTimeRatio = 1 //set this to 0.5, and you can fire again when the attack cool down is 50%.
ItemEvents.firstLeftClicked("iron_axe" ,event=>{
    const tickPerSecond = 20
    const {player, player:{uuid}, server:{tickCount}} = event
    const playerHashcode = uuid.hashCode()
    const lastLeftClickTime = MapPlayerLeftClickLastTime[playerHashcode] ?? 0
    const timeDifference = tickCount - lastLeftClickTime
    MapPlayerLeftClickLastTime[playerHashcode] = tickCount
    const playerAttackSpeed = player.getAttributeValue("minecraft:generic.attack_speed")
    if(playerAttackSpeed * timeDifference >= tickPerSecond * rechargeTimeRatio){
        player.tell("FIRE")
        player.damageHeldItem("main_hand")
    }
})
