v2.96.2

fixed SetCenter() bug.

BUG: The SetCenter() method does not set the TempTargetX and TempTargetY values ​​when the cam.SmoothType value is SmoothDamp or Lerp.

Full Changelog: v2.96.1...v2.96.2

v2.96.1

fix: platformer example window size.

Full Changelog: v2.96.0...v2.96.1

v2.96.0

• Removed unnecessary getter/setter methods. (breaking change.)

• Unnecessary Camera fields have been removed.

Full Changelog: v2.95.2...v2.96.0

v2.95.2

Change Log

• Added: (c *Camera) SetCenter(x, y float64)
• SetCenter() and SetTopLeft() resets follow position

v2.95.1

Change Log

Added

// Right returns the right edge position of the camera in world-space.
func (cam *Camera) Right() float64 {
	return cam.TopLeftX + cam.w
}

// Bottom returns the bottom edge position of the camera in world-space.
func (cam *Camera) Bottom() float64 {
	return cam.TopLeftY + cam.h
}

// SetTopLeft sets top-left position of the camera in world-space.
//
// Unlike the LookAt() method, the position is set directly without any smoothing.
//
// Useful for static cameras.
func (cam *Camera) SetTopLeft(x, y float64) {
	cam.TopLeftX, cam.TopLeftY = x, y
}

Changed

cam.topLeftX and cam.topLeftY are now exported.

cam.topLeftX -> cam.TopLeftX
cam.topLeftY -> cam.TopLeftY

v2.95.0

Change Log

• Fixed the issue where axis smoothing could not be disabled.
• Optimization with per-axis calculation has been improved.

Added:

(cam *Camera) XAxisSmoothingDisabled bool
(cam *Camera) YAxisSmoothingDisabled bool

(cam *Camera) smoothDampX(targetX float64) float64 // internal
(cam *Camera) smoothDampY(targetY float64) float64 // internal

Removed:

(cam *Camera) smoothDamp(targetX, targetY float64) (float64, float64)  // internal

v2.94.0

Change Log

Added

• (c *Camera) DrawWithColorM()
• /director_colorm example

Removed

• BB{}
• (c *Camera) BB()
• Internal vec2 struct

Renamed

CameraShakeOptions -> ShakeOptions
SmoothingOptions -> SmoothOptions
cam.Smoothing -> cam.SmoothType

Fixed

• retract v2.93.0
• Missing doc comments
• Bugs in examples

Updated

• Refactoring
• smoothDamp() belongs to the camera class and does not use vec2.

v2.92.0

Changelog

• Closes the #9 (Ability to control X and Y axes separately for smoothing settings.)

  func DefaultSmoothOptions() *SmoothOptions {
      return &SmoothOptions{
    	  LerpSpeedX:          0.09,
    	  LerpSpeedY:          0.09,
    	  SmoothDampTimeX:     0.2,
    	  SmoothDampTimeY:     0.2,
    	  SmoothDampMaxSpeedX: 1000.0,
    	  SmoothDampMaxSpeedY: 1000.0,
      }
  }
