spriteplus's Introduction

spriteplus

spriteplus is a golang library meant to be used along side the great Pixel library. It provides a generic SpriteSheet interface, and a few implementations.

Installation

go get github.com/cebarks/spriteplus

Usage

import "github.com/cebarks/spriteplus"

Sprite Sheets

//Create your sheet
sheet := spriteplus.NewSpriteSheet(false)

//Add your sprites to the sheet
err := sheet.AddSprite(gopherSprite, "gopher")
if err != nil {
  ...
}

//Optimize the texture
sheet.Optimize()


//These can be directly drawn to a Window (or any pixel.Target)
sprite := sheet.GetSprite("gopher") 
sprite.Draw(win, pixel.IM)

// or you can efficiently draw them using a batch with sheet.SourcePic()
pic := sheet.SourcePic()
batch := pixel.NewBatch(&pixel.TrianglesData{}, pic)

sprite.Draw(batch, pixel.IM)


batch.Draw(win, pixel.IM)

MakeAnimation always returns nil value

Hi there! I got stucked with MakeAnimation func as it is always returning nil value.

I've tried to make some really simple and basic thing like this:

       p1, _ := loadPicture("01.png")
	p2, _ := loadPicture("02.png")
	sprite1 :=  pixel.NewSprite(p1, p1.Bounds())
	sprite2 :=  pixel.NewSprite(p2, p2.Bounds())

	var Sprites []*pixel.Sprite

	Sprites = append(Sprites, sprite1, sprite2)

	anim, _ := spriteplus.MakeAnimation(Sprites, 2)
	fmt.Println("debug output is:", anim)
	anim.Draw(win, pixel.IM.Moved(win.Bounds().Center()))

debug output is: <nil>
