Functions ¶
func CheckCollision ¶
func CheckCollision(col1 BoxCollider, col2 BoxCollider) bool
func CheckOffsetCollision ¶
func CheckOffsetCollision(col1 BoxCollider, col2 BoxCollider, offset Vector2) bool
func LoadEmbeddedImage ¶
LoadEmbeddedImage loads a png from the embedded filesystem
Types ¶
type BoxCollider ¶
type CollisionData ¶
type CollisionData struct {
GameObject1 *GameObject
GameObject2 *GameObject
}
type GameObject ¶
type GameObject struct {
Position Vector2
CurrentSheet *SpriteSheet
Speed float64
Collider *BoxCollider
}
GameObject is the core component of ebitextras. It contains common information most objects in a game would need to have.
func (*GameObject) ChangeSheet ¶
func (gameObject *GameObject) ChangeSheet(newSheet *SpriteSheet)
func (*GameObject) DrawGameObject ¶
func (gameObject *GameObject) DrawGameObject(screen *ebiten.Image, ops ebiten.DrawImageOptions)
DrawGameObject draws the sub-image of the SpriteSheet for the current frame at the GameObject's position.
type SpriteLayout ¶
type SpriteLayout int
SpriteLayout defines whether a sprite sheet is formatted horizontally (rows are animations), or vertically (columns are animations).
const ( // Horizontal declares that a sprite sheet is formatted horizontally (rows are animations). Horizontal SpriteLayout = iota // Vertical declares that a sprite sheet is formatted vertically (columns are animations). Vertical )
type SpriteSheet ¶
type SpriteSheet struct {
// Image the ebiten.Image of the sprite sheet, or just the sprite if it is not animated.
Image *ebiten.Image
// Animated is whether the SpriteSheet is animated or just a single static image.
Animated bool
// Cells defines how many rows and columns the sprite sheet contains.
Cells Vector2i
// Frame is the current sub-image of the animation.
Frame int
// DelayFrames is the number of frames each sub-image of the animation is shown before changing to
// the next one.
DelayFrames int
// Layout specifies whether a sprite sheet is formatted in Horizontal (rows are animations) or
// Vertical (columns are animations) form.
Layout SpriteLayout
// SelectedAnim specifies the row or column (based on the Layout) that is currently selected.
SelectedAnim int
// Flipped flips the image when drawn to the screen
Flipped bool
// contains filtered or unexported fields
}
SpriteSheet stores the image of a sprite sheet and all necessary information to render and animate it. To use a non-animated static image, set Animated to false and do not call UpdateAnim on it. There is currently no support for animations composed of separate image files
func (*SpriteSheet) UpdateAnim ¶
func (spriteSheet *SpriteSheet) UpdateAnim()
UpdateAnim manages the timing and updating of a SpriteSheet. Call this during ebiten's Update function on each SpriteSheet that needs its animation to play.
type Vector2 ¶
Vector2 Utility struct to hold 2 floats.
