Ver. 0.8 out

[EkBass]

BazzBasic version 0.8

Key issues, news and changes from 0.7

NAudio to SDL2

This change has been done. It was actually easier to do what I expected.
Audio features works just as with version 0.7

RAD & DEG

Added keywords RAD & DEG

PI & HPI

PI returns a hard coded value of 3.141592653589793
HPI returns a hard coded value of 1.5707963267948966

These both are commonly and often used when playing with graphics. Hard coding them makes things much faster.

Fast Trigonometry (Lookup Tables)

For graphics-intensive applications (games, raycasting, animations), BazzBasic provides fast trigonometric functions using pre-calculated lookup tables. These are significantly faster than standard SIN/COS functions but have 1-degree precision.

Performance: ~20x faster than SIN(RAD(x)) for integer degree values.
Memory: Uses ~5.6 KB when enabled

FastTrig()

Enables or disables fast trigonometry lookup tables.

Parameters:

• TRUE (or any non-zero value) - Creates lookup tables
• FALSE (or 0) - Destroys lookup tables and frees memory

FastSin(angle)

Returns the sine of an angle (in degrees) using a lookup table.

Parameters:

• angle - Angle in degrees (automatically normalized to 0-359)

Returns: Sine value (-1.0 to 1.0)

Precision: 1 degree (sufficient for most games and graphics)

FastTrig(TRUE)

PRINT FastSin(0)    ' Output: 0
PRINT FastSin(90)   ' Output: 1
PRINT FastSin(180)  ' Output: 0
PRINT FastSin(270)  ' Output: -1

' Angles are automatically wrapped
PRINT FastSin(450)  ' Same as FastSin(90) = 1
PRINT FastSin(-90)  ' Same as FastSin(270) = -1

FastTrig(FALSE)

FastCos(angle)

Returns the cosine of an angle (in degrees) using a lookup table.

Parameters:

• angle - Angle in degrees (automatically normalized to 0-359)

Returns: Cosine value (-1.0 to 1.0)

Precision: 1 degree (sufficient for most games and graphics)

FastTrig(TRUE)

PRINT FastCos(0)    ' Output: 1
PRINT FastCos(90)   ' Output: 0
PRINT FastCos(180)  ' Output: -1
PRINT FastCos(270)  ' Output: 0

' Use in raycasting
FOR angle$ = 0 TO 359
    LET dx$ = FastCos(angle$)
    LET dy$ = FastSin(angle$)
    ' Cast ray in direction (dx, dy)
NEXT

FastTrig(FALSE)

FastRad(angle)

Converts degrees to radians using an optimized formula.

Parameters:

• angle - Angle in degrees (automatically normalized to 0-359)

Returns: Angle in radians

Note: This function doesn't require FastTrig(TRUE) but is included for consistency.

PRINT FastRad(90)   ' Output: 1.5707963267948966 (HPI)
PRINT FastRad(180)  ' Output: 3.141592653589793 (PI)
PRINT FastRad(360)  ' Output: 6.283185307179586 (2*PI)

Version 0.9

For version 0.9, I'm focusing on making sure that the metafiles etc. are in accordance with Windows and Avast reducing warnings when BazzBasic is run for the first time.

The easiest way would probably be to get an account in the Microsoft Store, but it costs money and I don't want to do that since it's a free open source project.

Most of the metafiles are already in order, but GitHub's own "release" method would help even more. However, I haven't had time to learn it yet.

Of course, bug hunting and fine-tuning are definitely expected with version 0.9.
