Sprites flying out a certain distance and then falling

iCodeForBananas commented 8 years ago

Happens on https://rangersteve.io when shooting. Maybe I should be specifying special slope properties just for bullets?

How I'm shooting the bullets

    let bullet = this.bullets.getFirstDead()
    bullet.body.gravity.y = -GameConsts.BULLET_GRAVITY // 850
    bullet.height = 2
    bullet.width = 40
    bullet.reset(x, y)
    let pointerAngle = this.game.physics.arcade.moveToPointer(bullet, currentWeapon.bulletSpeed) // currentWeapon.bulletSpeed === 2300
    bullet.rotation = pointerAngle

How I'm creating the bullets

    this.bullets = this.game.add.group()
    this.bullets.createMultiple(30, 'bullet')
    this.bullets.setAll('checkWorldBounds', true)
    this.bullets.setAll('outOfBoundsKill', true)

    this.physics.arcade.enable(this.bullets)
    this.game.slopes.enable(this.bullets)
    this.bullets.forEach(function(bullet) {
        bullet.body.height = 15
        bullet.body.width = 15
        bullet.height = 2
        bullet.width = 40

        // Define some shortcuts to some useful objects
        var body = bullet.body

        // Update player body properties
        body.drag.x = GameConsts.SLOPE_FEATURES.dragX
        body.drag.y = GameConsts.SLOPE_FEATURES.dragY
        body.bounce.x = GameConsts.SLOPE_FEATURES.bounceX
        body.bounce.y = GameConsts.SLOPE_FEATURES.bounceY

        // Update player body Arcade Slopes properties
        body.slopes.friction.x = GameConsts.SLOPE_FEATURES.frictionX
        body.slopes.friction.y = GameConsts.SLOPE_FEATURES.frictionY
        body.slopes.preferY    = GameConsts.SLOPE_FEATURES.minimumOffsetY
        body.slopes.pullUp     = GameConsts.SLOPE_FEATURES.pullUp
        body.slopes.pullDown   = GameConsts.SLOPE_FEATURES.pullDown
        body.slopes.pullLeft   = GameConsts.SLOPE_FEATURES.pullLeft
        body.slopes.pullRight  = GameConsts.SLOPE_FEATURES.pullRight
        body.slopes.snapUp     = GameConsts.SLOPE_FEATURES.snapUp
        body.slopes.snapDown   = GameConsts.SLOPE_FEATURES.snapDown
        body.slopes.snapLeft   = GameConsts.SLOPE_FEATURES.snapLeft
        body.slopes.snapRight  = GameConsts.SLOPE_FEATURES.snapRight
    }, this)

GameConsts just in case

// Physics
    MAX_VELOCITY_X: 500,
    MAX_VELOCITY_Y: 1000, // Max velocity before player starts going through the ground.
    BULLET_GRAVITY: 850,

    // Slope Plugin
    SLOPE_FEATURES: {
        acceleration: 1500,
        bounceX: 0,
        bounceY: 0,
        debug: 0,
        dragX: 1000,
        dragY: 100,
        enableGravity: true,
        frictionX: 0,
        frictionY: 0,
        gravity: 1100,
        jump: 450,
        minimumOffsetY: 1,
        pullDown: 0,
        pullLeft: 0,
        pullRight: 0,
        pullUp: 0,
        snapDown: 0,
        snapLeft: 0,
        snapRight: 0,
        snapUp: 0
    },

ugh i figured this out while typing the issue...

        body.drag.x = 0
        body.drag.y = 0

Yeah, be careful of drag, it rarely suits bullets! :grin:
