Blitz Basic Tutorial -

While modern game engines like Unity or Godot are powerful, they come with a mountain of boilerplate code and intimidating UI. BlitzBasic (specifically the free or BlitzMax ) strips everything back to the bare metal of BASIC .

Cls ; Clear the screen (paint it black)

; 1. Input (W/S for Left, Up/Down for Right) If KeyDown(17) Then p1_y = p1_y - 5 ; W If KeyDown(31) Then p1_y = p1_y + 5 ; S If KeyDown(200) Then p2_y = p2_y - 5 ; Up If KeyDown(208) Then p2_y = p2_y + 5 ; Down

Run that. You just made a physics engine. Sort of. 4. Input Handling (Keyboard) Blitz makes reading the keyboard stupidly easy using KeyDown() (holding) or KeyHit() (single press). blitz basic tutorial

At the top of your code (before the loop), load the sound:

; Apply movement x = x + dx y = y + dy

; Slow down the loop so it doesn't zoom too fast (50 milliseconds) Delay 20 Wend While modern game engines like Unity or Godot

To loop through all active players (useful for bullets or enemies), use For :

Flip ; Swap the back buffer to the front (show what we drew) Wend

; Keep ball on screen (Boundaries) If x < 0 Then x = 0 If x > 768 Then x = 768 If y < 0 Then y = 0 If y > 568 Then y = 568 Input (W/S for Left, Up/Down for Right) If

; Show FPS or instructions Color 255, 255, 255 ; White text Text 10, 10, "X Position: " + x

; --- Game logic goes here --- Text 10, 10, "Press Escape to quit"

Let’s modify our ball to move via the .
