Tool Task Experiment

Description of how it works

Three different methods of launching a ball, each with a different tool representation. Impact: The user hits a ball or puck. Slingshot: The user pulls the ball back, launching it (very similar to pinball) Curling: The user pulls the ball towards their intended direction.

Setup:

• GameObject.Find's all necessary gameobjects in task prefab, excluding those already found in BilliadsTask.
• Enables the correct tool according to the JSON.
• Sets the tilt if per_block_tilt_after_fire is false.
• Sets timer time based on JSON.
• Sets the surface materials based on JSON, using SetSurfaceMaterial in BaseTask.

Impact:

• Sets whether the user is launching a ball or puck, based on JSON.

Step 0:

Impact:

• Increments when mouse gets close to tool.

Slingshot:

• Increments when mouse gets close to ball.

Curling:

• Increments when mouse gets close to ball.

Step 1:

• Play audio cue and set missed to true if timer runs out.

List of JSON parameters

Key	Value	Description
exp_record_score	Boolean	Whether the "score" of the task is logged to result
per_block_type	"aligned" or "rotated"
per_block_rotation	Float	Perturbation angle
per_block_targetListToUse	List of floats	Angle in degrees of target (90 is forward)
per_block_tilt_after_fire	Boolean	Whether tilt is shown before or after firing
per_block_list_camera_tilt	List of floats	Tilt angle in degrees of camera, back wall, bonus text
per_block_list_surface_tilt	List of floats	Tilt angle in degrees of physics surface
per_block_surface_materials
per_block_track_score	Boolean	Whether this is a practice round
per_block_timerTime	Float	Time in seconds user has to fire pinball in order to receive points
per_block_list_triggerType	List of "impact", "slingshot", "curling"	Whether the experiment task will be impact, slingshot, or curling.
per_block_list_puck_type	List of "puck", "ball"	Whether impact will use a puck or a ball (visual change)
per_block_list_tool_type	List of "quad", "sphere", "cylinder"

instruction: Replaces trial with instruction trial that uses per_block_instruction.

aligned: Perturbation is disabled.

rotated: Perturbation is enabled. Initial ball direction is influenced by per_block_rotation.
