List of all members.

Public Attributes
ObjectTypes	type
	the type of the object, one of the ObjectTypes enum values
NSString *	imageFileName
	the image file for this object
NSString *	proximityWarningFileName
	the image file for the proximity warning used by this object
ImageOrientations	imageOrientation
	define how the image is oriented, Right means the sprite image is oriented to the right, Up to top, etc.
float	speed
	how fast the object moves, good values are in range 5-40
float	rotationSpeed
	how fast the object will rotate to face the direction it is moving to, it's in fractions of a second, a good value is 0.5f
float	touchRadius
	how big the touch area of the object is where it recognizes a touch, typically twice the size of the collision radius
float	collisionRadius
	how big the collision radius is, if anything gets closer than collisionRadius pixels the object will collide (crash)

Member Data Documentation

float ObjectDef::collisionRadius

how big the collision radius is, if anything gets closer than collisionRadius pixels the object will collide (crash)

NSString* ObjectDef::imageFileName

the image file for this object

ImageOrientations ObjectDef::imageOrientation

define how the image is oriented, Right means the sprite image is oriented to the right, Up to top, etc.

If you notice that your images are rotated at 90 degrees or backwards compared to the movement direction then you need to adjust this property and set the correct orientation for your images. I assume most images are drawn pointing upwards so the most commonly used value will be ImageOrientationUp.

NSString* ObjectDef::proximityWarningFileName

the image file for the proximity warning used by this object

float ObjectDef::rotationSpeed

how fast the object will rotate to face the direction it is moving to, it's in fractions of a second, a good value is 0.5f

float ObjectDef::speed

how fast the object moves, good values are in range 5-40

float ObjectDef::touchRadius

how big the touch area of the object is where it recognizes a touch, typically twice the size of the collision radius

ObjectTypes ObjectDef::type

the type of the object, one of the ObjectTypes enum values
