Details

Primitive entities in jasmines are tibbles with four columns: x and y specify co-ordinate values, the id is a number identifying the object, and the type is a character label indicating what kind of entity it is. By default, entities are assigned a random integer as the id code, but it is often wise for the calling function to assign the id in a more predictable fashion. The shape parameter can sometimes be a list.

Value

A tibble with four columns: x, y, id and type

Locate entities

Description

Locate entities

Usage

locate_entity(entity, xpos = 0, ypos = 0, size = 1, angle = 0, ...)

Arguments

The entity to be placed
xpos

The horizontal location of the entity
ypos

Details

When a jasmine entity is created it is implicitly assumed to be located at the origin (xpos = 0, ypos = 0), to have size 1, and to have a horizontal orientation (angle = 0). The locate_entity function allows the entity to be transformed in simple ways: translation, dilation and rotations
