Constructor & Destructor Documentation

JAM_ParticleEffect::JAM_ParticleEffect	(	std::string	fileName,
		JAM_Vec2	emitter,
		bool	emit,
		SDL_Renderer *	renderer,
		int	screenHeight
	)

Constructs the ParticleEffect Object.

Parameters

objectName	The file name of the texture that the Particle will use.
emitter	The position that the particle effect emits from.
emit	The new value of the emit boolean.
renderer	A pointer to the renderer.
screenHeight	The screen height.

		int	screenHeight
	)

Constructs the ParticleEffect Object.

Parameters

emitter	The position that the particle effect emits from.
emit	The new value of the emit boolean.
renderer	A pointer to the renderer.
r	The red value (0-255).
