Initialising our Environment (cont.)

The first variable is simply the number of the box. In this case, we’re located inside box no. 1 (“column1”). The next three variables are the starting and ending number and the number of objects (“startnum”, “endnum” and “numberofItems”). We then determine the coordinates of the mouse by storing them in the next two variables “mouseposX” and “mouseposY”. Furthermore, we need counters for the loops, which are called “i” and “m”. Finally, we reset two variables, “filledSpace” and “gapSpace”, which will be discussed later in this document.

Since we want our objects to have an original position, we need to make an array, which holds these values. When we have stored an original vertical position for each object, we reset “i” for further usage and ensure that these actions will only be performed the first time, by setting “myInit” to true (the actions are only carried out, if “myInit” is false). As mentioned, we only want to apply a scale and alpha value to each object, if the mouse is located inside the box and thus we need to know the borders, which the next four variables take care of (“boundleft”, “boundright”, “boundtop” and “boundbottom”).

After we have initialised our environment, we have two cases, where mouse is located either inside the box or outside the box.
