I'm posting a couple in-dev Scruffy scripts to help out some people doing 2D like games (as everybody has my 3D scripts.)

This is the balloon snake, he's a snake built up of a bunch of balloons. Every hit pops up a balloon and speeds up the snake a bit. All the snake does is get spawned and then go until it hits something and then turns around (very much like a green mario turtle.)

Code:

var balloonPop=0;

var balloonDamageTick=0;

function snakeConstruct(obj)

{

    obj.model.on=true;

    obj.model.name="Balloon Snake";

    obj.model.lit=DIM3_MODEL_LIT_VERTEX;

    obj.model.shadow.on=true;

    obj.setting.suspend=false;

    obj.setting.damage=true;

    obj.setting.invincible=true;

    obj.setting.ignorePickUpItems=true;

    obj.setting.singleSpeed=true;

    obj.forwardSpeed.acceleration=100;

    obj.forwardSpeed.deceleration=100;

    obj.turnSpeed.facingWalk=360;

    obj.turnSpeed.motionWalk=360;

    obj.lock.z=true;

    obj.size.x=1400;

    obj.size.z=1400;

    obj.size.y=5500;

    obj.size.weight=10000;        // don't be pushed around by explosions

    obj.melee.strikeBoneTag='base';

    obj.melee.strikePoseName='Idle';

    obj.melee.radius=2500;

    obj.melee.distance=0;

    obj.melee.damage=5;

    obj.melee.force=10;

}

function snakeSpawn(obj)

{

    var            i;

    obj.model.animation.showOnlyMesh('Seg0');

    balloonPop=0;

    obj.model.offset.y=0;

    obj.size.y=5500;

    obj.forwardSpeed.walk=30;

    obj.angle.rotateTo(270);

    obj.model.rotate.y=280;

    obj.motionVector.go();

    obj.model.animation.start('Walk');

}

function snakeCollide(obj)

{

    if (obj.angle.y==90) {

        obj.angle.rotateTo(270);

        obj.model.rotate.y=280;

    }

    else {

        obj.angle.rotateTo(90);

        obj.model.rotate.y=80;

    }

}

function snakeTouch(obj)

{

        // reverse snake

    snakeCollide(obj);

        // hurt player if touching

    if (obj.touch.objectId==map.object.findPlayer()) obj.melee.spawnFromObjectBone();        

}

function snakeDamage(obj,tick)

{

        // can only damage once per 1/2 a second

    if (balloonDamageTick>tick) return;

    balloonDamageTick=tick+500;

        // pop balloon

    balloonPop++;

    sound.play("Cloud Pop",obj.position.x,obj.position.z,obj.position.y,(0.5-((4-balloonPop)*0.15)));

        // snake all gone?

    if (balloonPop==4) {

        obj.motionVector.stop();

        obj.setting.hidden=true;

        obj.setting.contact=false;

        return;

    }

        // remove a balloon

    obj.model.animation.showOnlyMesh('Seg'+balloonPop);

    obj.size.y-=1400;

        // speed up snake

    obj.forwardSpeed.walk+=20;

        // turn snake around

    snakeCollide(obj,tick);

}

//

// events

//

function event(obj,mainEvent,subEvent,id,tick)

{

    switch (mainEvent) {

        case DIM3_EVENT_CONSTRUCT:

            snakeConstruct(obj);

            return;

        case DIM3_EVENT_SPAWN:

            snakeSpawn(obj);

            return;

        case DIM3_EVENT_COLLIDE:

            snakeCollide(obj);

            return;

        case DIM3_EVENT_TOUCH:

            snakeTouch(obj);

            return;

        case DIM3_EVENT_DAMAGE:

            snakeDamage(obj,tick);

            return;

    }

}
