Package venture

Overview ▾

Package venture provides a game engine powered by ebiten.

Overview

The building blocks of venture games are nodes. Everything displayed on the screen is a node. For instance, a node could be a single line of text on the screen, a bouncing ball, or a scene which contains a line of text and a bouncing ball.

Nodes

Nodes may be any type which implement the following:

type Node interface {
    AddNode(Node)
    Nodes() []Node
    Update(screen *ebiten.Image) error
    Draw(screen *ebiten.Image)
}

Three types of nodes are provided by venture:

- Logic, an invisible node

- Sprite, a graphical node

- Scene, an organizational node

Event Loop

Once a venture game has started, with each tick the game's UpdateFunc is called, followed by calling the Update method of the root node and any contained nodes.

While a reference to the screen is provided to Update, any modifications must be made in Draw.
