McAvatar

McAvatar is a Minecraft Spigot plugin for granting players elemental bending abilities. The plugin is not complete, but currently offers earthbending and firebending.

Development

The code is in Kotlin instead of Java because Kotlin is kool (aka, code tends to be more expressive, readable, and concise).

A custom Spigot gradle plugin is used to automatically download the current Minecraft version. In theory, all you have to do is this to get started:

# Download Spigot
./gradlew spigotBuild

# Run the Server
./gradlew spigotRun

If running for the first time, you may need to accept the EULA.

Testing

Testing a spigot plugin is admittedly difficult, but the World can be faked using a test double. Here's an example test:

@Test
fun `entity is in the air`() {
    TestBukkit.world {
        val ground = block(Material.DIRT) {
            at(0, 0, 0)
        }

        val player = entity {
            at(0, ground.y + 1.5, 0)
        }

        assertThat(player located inAir).isTrue()
        assertThat(player located onGround).isFalse()
    }
}
