  1. ;Player bullet handlers
  2. ;
  3. ;PBT located at $8D00
  4. ;First 64 bytes is PBT's FBT, all are filled with values indicating player
  5. ;bullet's LSB base location (multiples of 3 starting at $8D40
  6. ;Last 64*3 bytes is PBT's actual bullet data entries, described below, but
  7. ;is up to called routine's interpretation.
  8. ;
  9. ;FBT's location is in (pbtfreebullet). If bit 6 is ever set, then the FBT
  10. ;is full.
  11. ;
  12. ;Important note: Character's X and Y positions are not stored as normal. There
  13. ;are two bits of accuracy at the start so you're going to have to right-shift
  14. ;twice to get the actual X,Y positions.
  15. ;
  16. ;Y = YYYY YYSS , where S is subpixel data
  17. ;X = XXXX XXSS , where S is subpixel data
  18. ;
  19.  
  20. ;Player bullet structure (3 bytes)
  21. ;+0 : YTTTTTTT, T=Timer 0-127, Y=1 if focused shot
  22. ;+1 : Y position if applicable
  23. ;+2 : X position if applicable
  24.  
  25. ;The routine that is being called must be able to distinguish between
  26. ;unfocused and focused modes, since there won't be seperation at
  27. ;this stage of the routine call.
  28. ;
  29. ;Several things to edit.
  30. ;(1) PBTPlayerRoutineTables : How bullets are created. Below it are links.
  31. ;(2) PBTPlayerTypeTables : Types of bullets and how they move
  32. ;
  33. ;You can make creative use of the game timers to tell bullets apart
  34. ;(gametimer1) by creating only certain ones on certain slices of masked time.
  35. ;A good mask might be like %00000111 so you get 8 different time slices on
  36. ;each processing. Also pay attention to firing delays or you might not ever
  37. ;get a single bullet out.
  38. ;
  39. ;Other than that, good luck. You're gonna need it.

  535. NanamiP1U:
  536.  ; This attack sends a single shot out in a arch with the shape of
  537.  ;                _----_
  538.  ;               |      |
  539.  ;                \    /
  540.  ;                 \  /
  541.  ;                  \/
  542.  ;                   X
  543.  ; where X is nanami
  544.  ; it follows this path unless 2nd is released in which it takes the most linear path back to nanmi from its current
  545.  ; position
  546.  ;
  547.  ; This attack also starts the arc in a different direction based on which direction you were traveling last
  548.  ;
  549.  ; This has a look up table at Nanami45LUT that is aligned on the LUT page
  550.  ; This LUT contains the offsets from the firing position of nanami that makes it have this proper arc
  551.  ; by doing it this way its much faster and causes less of a headache.
  552.  ; When second is released we will be having the bullet come back to nanami this will be done with a arctan look up.
  553.  ; going to see if i cant get away with reusing some of iambians enimy routines here have to lookinto the track function
  554.  ; - 5 minutes later -
  555.  ; we can use the call r.arctan to get the angle and return it in C
  556.  ;
  557.  ; TTl of bullet.
  558.  ; i have no clue how to do this other than doing blatant collision detection with your self ask iambian
  559.  
  560.  ; LUT is organized as such
  561.  ; 2 bytes per pair
  562.  ; a pair consists of a counbt and a angle/2
  563.  ; so
  564.  ; .db 20,45
  565.  ; would move the bullet at a 90D angle for 20 game cycles
  566.  ; angle/2 is because we can not fit more than 127 different angles in the counter var i am using
  567.  ; char weapon dat serve a few purposes.
  568.  ; bit 7 is our left/right indicator
  569.  ; and the lower 7 bits are angle ttl
  570.  ; it set move left if reset move right
  571. ; [22:50:17] <+Iambian> If we really want this thing to be like fukken amazing, I suggest a particle trail :)
  572. ; [22:50:32] <+Iambian> A particle trail made of bullets
  573. ; [22:50:32] <@geekbozu> or a rotating thing
  574. ; [;22:50:35] <@geekbozu> and done
  575. ; [22:50:36] <@geekbozu> totally done
  576. ; [22:50:49] <@geekbozu> have to think of how to do that tho...
  577. ; [22:50:52] <@geekbozu> eh not to hard
  578. ; [22:50:54] <+Iambian> Bullets that can so totally damage the enemy
  579. ; [22:51:25] <@geekbozu> uhm consequences of calling the pbtbullet create routien while in bullet movement code?
  580. ; [22:51:47] <+Iambian> Without preserving SP? Epic fail.
  581. ; [22:51:59] <@geekbozu> well yeah presering sp obviously
  582. ; [22:52:12] <@geekbozu> (same trick as used to call the sprite routien)
  583. ; [22:52:25] <+Iambian> Yeah, well that should work.
  584. ; [22:52:37] <+Iambian> For creating the trail...
  585. ; [22:52:43] * @geekbozu adds some comments to his noteblock
  586. ; [22:53:22] <@geekbozu> also i intend to just create bullets at semi random intervals with semi random velocities that are slower than the orb
  587. ; [22:53:26] <@geekbozu> and it should make a nice effect
  588. ; [22:53:37] <+Iambian> I suggest getting the current angle that the thing is heading in, negating that so it goes in the opposite direction, then adding an angle that is plus or minus some amount. Probably similar to how the dragonfire is done, except the revised full-range code should be used
  589. ; [22:53:55] <@geekbozu> yeah more or less what i am thinking
  590. ; [22:54:07] <@geekbozu> but thats at a later date
