Motion Effect Rows Dialog
|Top Previous Next|
This dialog window serves 2 distinct purposes:
•When right-clicking on a prop or motion effect row in a sequence's Item List and selecting "Add/Modify motion effect rows" from the pop-up menu, you add or modify motion effect rows in the sequence. Any changes made while in this dialog will be applied to the sequence after clicking the "OK" button.
•When clicking on the "Motion Effect Rows" button in Prop Definition or Group Definition, you can define motion effect rows that will be applied when new sequences are created. It does not change existing sequences.
Motion effect rows do not have to apply to all of the pixels in a prop (or group). Using this dialog, you can specify that a motion effect row applies to:
•all of the pixels in a prop or group (subsection=none)
•a rectangular subsection of the prop's pixels (subsection=rectangle). For example, you could divide a pixel tree into tiers.
•a custom set of pixels chosen by you (subsection=custom). For example, you could draw a face.
When motion effect rows are displayed in a sequence's Item List, the row name is displayed with a square icon suffix to indicate those rows apply to a subsection of the prop or group. Rows with subsection=none are displayed without the suffix, indicating they apply to the entire prop or group.
Motion effect rows in a sequence
In the window, the current set of motion effect rows are listed in the table on the left, and the prop's pixels are shown on the right. If you click on a row in the table on the left, then the pixels used by that entry will be graphically represented on the right.
Within this dialog you can:
The Motion Effect Rows Dialog
Clicking the "Add Row" button will add a new motion effect row to the table. The new row will use all of the pixels in the prop or group (the Subsection field will be set to "none").
By default, motion effect rows are named "Effects 01", "Effects 02", etc. You can change the name of a row by clicking on the name in the table, and then typing the new name.
Using the "Subdivide" button, you can divide the pixels into rows and columns, creating a separate motion effect row for each section.
The following picture shows a 16x50 pixel tree subdivided into 2 columns and 2 rows. There will be 4 new motion effect rows created, with each subsection being 8x25 pixels
Subdividing a pixel tree into 2 columns and 2 rows
After clicking "OK" in the Create Subsections dialog, this is the result. The "r" in the name stands for "row" and the "c" stands for "column". Notice that clicking on a row in the table graphically displays the subsection on the right.
Result of subdividing the pixel tree into 4 sections
While the "Subdivide" button is very convenient for creating equally sized subsections, you might have need to manually specify a subsection. You can do this by making sure the "Subsection" drop-down is set to "rectangle" for the motion effect row, and then manually typing the values for left, top, width, and height.
Custom subsections allow you to do things like define singing faces on a pixel matrix or pixel tree. You can also use it to define sections of a pixel-based custom shape -- for example arms of a snowflake.
Defining a custom set of pixels to be controlled by the motion effect row
The first step is to change the "Subsection" drop-down to "custom". Once that is done, you will notice that the toolbar on the right side is now enabled.
•Use the "pencil" tool to turn on pixels (make them part of the subsection). Left-click on a pixel in the diagram to turn it on, or drag across the diagram with the left mouse button depressed to select multiple pixels at a time.
•Use the "eraser" tool to turn off pixels (remove them from the subsection). Left-click on a pixel in the diagram to turn it off, or drag across the diagram with the left mouse button depressed to deselect multiple pixels at a time.
•Use the "move" tool to reposition the selected (on) pixels.
•Use the "clear all" tool to turn off all of the pixels. This is useful if you want to start over with your custom selection.
•Use the "Show all" check box to show all of the motion effect rows with a "custom" subsection on the diagram at the same time. For example, if you are drawing a face on a pixel matrix, you might first draw the outline of the head on one motion effect row. Then you might draw the eyes on another row. While drawing the eyes, it is useful to see where the outline of the head is, so you would keep "Show all" enabled.
You can copy the contents of the motion effect row table to the clipboard, and then use the paste button to append the data into the Motion Effect Row dialog for another prop. This can be useful:
•To copy motion effect rows defined in a sequence to the motion effect row defaults for a prop or group, so they will be applied whenever a new sequence is created.
•To copy motion effect row defaults you just created on a prop or group into existing sequences.
•To copy motion effect rows defined in one sequence to the motion effect rows for a same prop or group in another sequence.
•To copy motion effect rows defined on one prop to other props with the same shape and dimensions. For example, you might define some motion effect rows for a pixel-based mini-tree and copy those rows into your other mini-trees.
