Objects without code

You want a floor, a wall or a spike: things that just sit still in the level. They don’t need code.

Create

In Recursos (Resources), right-click a folder and choose Novo objeto (sem código)… (new object, without code). The object is created with the data only: sprite, Sólido (solid), mask, physics and everything else in the Inspector.

Drag it into the room like any other object.

React to it in the code

An object without code has no class, so you can’t write onCollide<Espinho>. Use the object’s name in quotes:

void Player::onSpawn() {
    onTouchStart("Espinho", [this](Entity&) { restart(); });
}

The functions that take the name:

To	Functions
Know whether it touches	touching("Espinho"), collidesAt("Espinho", x, y + 1), findAt("Espinho", x, y)
React to contact	onCollide("Espinho", ...), onTouchStart("Espinho", ...), onTouchEnd("Espinho", ...)
Count and loop	count("Moeda"), any("Moeda"), each("Chao", ...), destroyAll("Moeda")

They also work for objects that have a class.

Floor and walls

To keep the player from going through an object, just check Sólido on it: moveAndStop and placeFree already respect every solid, with or without code.

When to create the code

An object without code has no events and no variables in the code. If it needs to move, count time or keep a value, create it with Novo objeto… (new object).
