- ----------- SpriteST -----------
- --- by CHRIS GREEN (ME) 1989 ---
-
- --------- Instructions ---------
- ------------ (V1.0) ------------
-
-
- SpriteST is a versatile, cheap!
- (ie for nothin') sprite designer
- for, of course, designing sprites
- to use in your own programs. Or
- you could just use it to try your
- hand at animaing objects and creating
- your own short "stories".
-
- There are four different sizes of
- sprite possible; having a width of
- either 16 or 32 pixels, and also
- either a heght of 16 or 32 pixels.
- You can use all 16 colours and mix
- your own colours from the ST's
- standard palette.
-
- You can have up to 128 different
- sprites(Frames) and string them
- together into an animation "sequence".
- This sequence can be up to 140 frames
- in length, but of course some sprites
- would have to be shown twice.
-
- On the main screen you will see
- the main grid which shows a
- magnification of the current frame.
- Clicking in that grid will set that
- particular square with the currently
- selected colour.
-
- In the top right hand corner is the
- current frame number, beneath that
- is the sprite shown exactly as it
- would appear in your programs,
- i.e. its true size.
-
- On the middle right are the 16
- colours in the current palette, with
- the currently selected one denoted
- with a 'tick'.To change the 'pen'
- colour, just click on whichever
- colour you wish to use.
-
- Below that, in the bottom right-
- hand corner are 12 icons, through
- which you tell the program what to do
- with your sprite.
-
- The icons are:
-
- SAVE : (1st row,1st column)
-
- This icon does exactly as it
- suggests, saves all sprites to disk,
- displaying the standard GEM file
- selector through which you can select
- a file to save to or create a new one
-
- LOAD : (1st row,2nd column)
-
- To load in a previously saved
- file, click on this icon.The load
- will fail if the file is not the
- correct format (more about that in
- a bit).REMEMBER TO SAVE ANY SPRITES
- THAT ARE ALREADY IN MEMORY BEFORE
- LOADING ANY NEW ONES IN.
-
- QUIT : (1st row,3rd column)
-
- This icon (the one with the 'Q'
- on it) will QUIT SpriteST and return
- to DESKTOP, but asks for confirmation
- first, just in-case.
-
- FLIP : (2nd row,1st column)
-
- You can flip the current sprite
- using this icon either horizontally
- or vetically, just click on the icon
- and you will be asked which way, or
- to cancel if you have changed your
- mind.
-
- CLEAR : (2nd row,2nd column)
-
- This will clear the current
- sprite to the background colour,
- and asks for confirmation first.
-
- FILL : (2nd row,3rd column)
-
- Clicking on this icon will
- fill the whole sprite with the the
- currently selected colour,this also
- asks for confirmation.
-
- ANM ON : (3rd row,1t column)
-
- This will turn the animation
- on (ANM ON!) pressing enter will
- stop the animation and return you
- to designing your sprites. Of course,
- if you haven't set any animation
- (using the next function), animation
- will not be turned on.
-
- ANM SET : (3rd row,2nd column)
-
- To set the various parameters
- of the animation, use this function.
- All about this later.
-
- COL SET : (3rd row,3rd column)
-
- This function changes the RGB
- values of the current colour. A
- small box will appear in the bottom
- right corner with the RGB value of
- the colour. Clicking on the up
- arrow increases the value, the down
- arrow to decrease. Double-click to
- return to your drawin'.
-
- RESIZE : (4th row,1st column)
-
- You can change the size of the
- current sprite using this icon. You
- will be asked for the width+height.
-
- NOTE:If a sprite is resized, all
- previous data will be erased. if you
- stumble into this by accident, set
- the values to the same as the current
- sprite and nothing will happen.
-
- FRAME FORWARD : (4th row,2nd column)
-
- This will move you onto the
- next frame, up to a maximum of 128.
-
- FRAME BACK : (4th row,2nd column)
-
- This will move you back to the
- previous frame, down to number 1.
-
-
-
-
-
- ------------ ANIMATION ------------
-
-
-
- You can animate frames, of different
- sizes, by following the following
- steps:
-
- 1: Draw your sequence.
-
- 2: Click on the ANM SET icon.
-
- You will first be asked whether
- you want to load in a previously
- saved sequence. Then comes a little
- reminder, press RETURN and up comes
- a sequnce of numbers. These are the
- order in which you would like your
- frames to be shown in the sequnce.
- Move about the grid using the cursors
- and type in your sequnce.When
- finished, you will be asked what
- speed you would like the animation
- to run at, and what happens at the
- end. These can be either:
-
- LOOP - When the animation
- reaches the end of
- your sequence, the
- sequence loops back
- to the beginning
- and starts again.
-
- STOP - At the end of your
- sequence, animation
- stops and you can
- press SPACE to see
- your sequence again.
-
- GO BACK - At the end of your
- sequence,animation
- then flows backwards
- through your sequence
- upon reaching the
- beginning when it
- loops through again.
-
- When you have finished watching
- your sequence, press RETURN to end
- and enter the drawing again.
-
-
- ----- SpriteST File Format -----
-
-
- The sprite files saved using
- SptiteST have the following format:
-
-
- 4.L(16 bytes) - these 1st four
- long words are used internally by
- SpriteST to signal where certain
- sprites should appear within the
- block of 128.
-
- 1.W(2 bytes) - this contains the
- number of sprites in the file.
-
- 16.W(32 bytes) - this is the colour
- palette which the sprites use.
-
- Following these is the sprite
- data,each block of data has the
- following format:
-
- 1st byte - width of sprite.
- 2nd byte - height of sprite.
-
- The actual sprite data appears
- here. Which is either 128, 256
- or 512 bytes in size, depending
- on the size of the sprite.
-
-
-
- ---- Animation Set File Format ----
-
-
- This file is 174 bytes long. The
- first 140 bytes are the numbers of
- the sequence, the rest are used
- internally.
-
-
- --------------- Demo ---------------
-
- On the disk is a short demo to get
- you used to using the various
- features of SpriteST. It is 12 frames
- of dripping water. Load the sprites
- in and set the animation for the 12
- frames, they run straight through
- from 1 to 12. Change the other
- settings to see the differences. Feel
- free to change any of the sprites to
- do what you want.
-
- That's just about all you need to
- know about creating your own sprites
- using SpriteST, hope you have fun,
- and watch out for updates and later
- versions containing many extra
- features and improvements.
