Moving platform code

It adds the platform’s speed to the player’s position (x coordinate) and its own position (x coordinate).

This is old code! And it is combined with “pixel perfect” functions for its collisions.

this.player_touch = false;
this.direction = 0;
this.SPEED = 5;
project.TILES.push(eval(this._identifier));

this.update_hitbox = function () {
    this.hitbox = project.get_tile_hitbox(eval(this._identifier));
};

this.update_hitbox();

onEvent('update', function () {
    if (this.x > 245 && this.direction === 0) {
        if (this.player_touch) {
            player.x -= this.SPEED * player.delta_time;
        }
        this.x -= this.SPEED * player.delta_time;
        this.update_hitbox();
    }
    else if (this.x < 465 && this.direction === 1) {
        if (this.player_touch) {
            player.x += this.SPEED * player.delta_time;
        }
        this.x += this.SPEED * player.delta_time;
        this.update_hitbox();
    }
    else {
        this.direction = ((this.direction === 0) ? 1 : 0);
    }
});

Lockable door

It checks if the “key” or moved block has reached the “key hole”. If it did, then open the door; else, lock it. For the locking part, it just disable the “teleportation”.

the “key hole”'s code:

onEvent('update', function () {
    if (this.hitTest(box1)) {
        door.locked = false;
    }
    else {
        door.locked = true;
    }
});

the door’s code:

this.locked = true;

onEvent('update', function () {
    if (this.locked === false) {
        if (this.hitTest(player)) {
            gotoNextFrame();
        }
    }
});

Thanks! I’m watching this forum, but I’m inactive for making games, proof of concepts, and stuff. School is the first priority! Even when I don’t want school. . .
