ANIMATIONMANAGER Provides per frame paths for stimuli We integrate dyn4j java physics engine for rigid body. The plan is to also support sinusoidal, brownian, circular etc.
screen = screenManager(); % create a screen object
ball = imageStimulus('size',4,'filePath','moon.png','name','moon');
ball.speed = 25; % will define velocity
ball.angle = -45; % will define velocity
world = animationManager('timeDelta', 0.016);
screenParamaters = open(screen); % open screen
% initialise stimulus with PTB screen parameters
setup(ball, screen);
addScreenBoundaries(world, screenParamaters); % add floor,ceiling and walls based on the screen
addBody(world, ball); % add stimulus as a rigidbody to animationManager
% initialise the simulation and pass the PTB
% screen so that the world can be related
% to the PTB dimensions.
% The mapping is 1° visual angle = 1 meter.
setup(world, screen);
for i = 1:120 % run for 120 frames
draw(ball); % draw the stimulus
flip(screen); % flip the screen
% step the simulation one step (0.016s) forwards
% true flag will update the ball stimulus at the new position
step(world, 1, true);
end
@TODO build the code for the different types of motion paths apart from rigid body 2D physics. These could be static methods.
