One or more lines.
If an element can end on its own, you don't need to set end conditions for it in property end (unless you want it to maybe end earlier).
No—runs until a condition you set in property end.
You can vary or allow the subject to adjust the following input properties of an object of this type in real time when it's running. If you need to make other properties adjustable, you can edit the element type code—see Element Type Programming Manual.

nn_eyes
rotation

No default
A 1×4 vector <cd>[x1 y1 x2 y2]<cd> setting line start and end points (deg). Coordinates are relative to element position which you can set in position (default relative to screen center).
Or if you want to show multiple lines at the same time, use an n×4 matrix with rows corresponding to lines. This is more efficient than using multiple line elements. Lines are layered front-to-back in the order you specify them. If you show multiple lines then for each of the properties below you can set one value for all of them, or you can set different values for different lines using a vector or matrix (see property).
Default: 0.075 deg
A number setting line width (deg). Or a 1×n vector for different widths for different lines.
Default: white
A 1×3 RGB vector with numbers between 0–1. Or an n×3 matrix for different colors for different lines.
PsychBench uses record properties to record information during experiments. You can't set record properties but you can see them in experiment results by listing them input property report.
