| Title: Curved Text & RLE vector routines (part 2)
| Code Submitted By:
- andy_a
| This code snippet will run as is, but you'll need part 1 for creating and saving images in your own program. The new functions are:
makeData() - makes a text file of data statements that can be copy & pasted into your source code.
getImgData() - once you've pasted the data statements into your source, use this function to load into memory for further processing.
data2buffer() - like the above, but will re-create the image at 0, 90, 180, 270 degrees (user specified) in a Blitz image buffer. Use the Blitz image buffer just like you would use any loaded external image file.
dat2curv2buf() - reads the image in the data statements, wraps the image around a curve, and stores in a Blitz image buffer.
Simple usage demo included. |

| Title: Non-Type Based Vector Lib
| Code Submitted By:
- world_creator
| | Basically instead of having to deal with type declarations (ie. the myVector.Vector) you can use handles to banks instead (ie. just myVector). I've written it with some basis on "temporary" vectors which are deleted automatically when used in a non-value-returning vector function. Included are functions to find the pitch and yaw of a vector, two methods of finding the angle between two vectors, and all three projections. |

| Title: Number Base Conversion with String to Float Capability.
| Code Submitted By:
- jimpishlo
| The first of the functions in the code 'xBase2Int' will convert a string holding either a binary, octal, decimal, or hexidecimal value into an integer. See comments for using this function.
The second function 'String2Float' will convert a float value stored in a string into the most accurate float value the system can provide. See comments for use.
Enjoy,

| Title: Quicksort Algorithm Demo
| Code Submitted By:
- kawaguy
| This demo is to implement fast Quicksort Algorithm.
Use a keyed structure (type) for records to be sorted. In this example, random numbers are used for the demo purpose.
For 10,000 records, sorting takes approx. 6/10 of a second on my machine as compared to Bubblesort, approx. 4 secs. If you do the timing yourself, be sure to comment out DebugLog commands.

| Title: Replaying user input using a collection of Types
| Code Submitted By:
- matt_sephton
| 23/24 June 2002, version 0.10, tracks user controlled element
26/27 June 2002, version 0.20, tracks multiple computer controlled elements
to do: enable early quit of replay to go back to game
*** feel free to use this method as long as you give me credit
this method can be used to replay user input. this simple demo records the player control of a dot. we choose to do the correct branch of the main loop (moving or drawing) depending on if we are recording (game) or replaying (watching). this could be extended to keep track of multiple items, such as computer/AI controlled characters.

| Title: Return Values Based on Probability
| Code Submitted By:
- shaunsullivan
| This include will allow you to add a number of possible outcomes
(string, int or float), and assign each outcome a relative weight. Then, you can call a function that will return an outcome based on the weight.
For example:
prob_init() ; must call init
prob_add_str(10,"shaun")
prob_add_str(40,"collin")
prob_add_str(50,"sam")
local s = prob_roll_str()
; So with the above code it is 10% likely we'll return "shaun", 40% chance we'll return "collin" and 50% chance we'll return "sam"
;(note the weights are just relative, they need not add up to 100) |

no comments.
most likely you wont be able to modify and still work unless you are a blitz guru.
must create your own "kite.bmp" image.
if it dont work use:
Global sd=16
...or else just use that instead to be on the safe side. |
