You can even make fields arrays of types! Very nice...
Const ASDNumAllowedCollisions = 20
Const ASDNumOffsetLayers = 10
Const ASDNumSprites = 100
Const ASDNumTexts = 10
Const ASDDebug = 1 ; 0 to remove debug messages
; 1 for debug messages
Type AlmoSpriteDriver
Field BackgroundImage ; Expects handle to be in upper-left corner
Field BGOffsetLayer
Field CLSEachFrame
Field DefaultFont ; after calling ASDUpdate, this font will be the Text-ing font
; specify -1 (the default) and ASD will leave the Text-ing font the
; same as that of the last drawn Text.
Field DrawBG
Field OffsetLayers.ASDOffsetThing[ASDNumOffsetLayers]
Field Sprites.ASDSprite[ASDNumSprites]
Field Texts.ASDText[ASDNumTexts]
Field Initialized
End Type
Type ASDOffsetThing
Field x#, y#
End Type
Type ASDSprite
Field Image
Field x#, y#
Field Active ; 0 - sprite is inactive, doesn't do anything
; 1 - sprite is active, draws, etc.
Field Collides ; -1 - sprite doesn't collide
; 0 - sprite collides with all other sprites with Collides >= 0
; >= 1 - sprite collides with all other sprites with same Collides value
; and those with Collides = 0
Field OffsetLayer
Field Collided[ASDNumAllowedCollisions] ; max allowed collisions a sprite will store.
; subsequent collisions ignored
Field NumCollisions ; indicates number of collisions this frame
End Type
Type ASDText
Field theText$
Field x, y
Field CenterX, CenterY
Field OffsetLayer
Field Active ; 0 or 1, whether to draw or not
Field OnTop ; 0 or 1, whether it shows up on top of other sprites
Field theColorR, theColorG, theColorB ; color of text
Field Font
End Type
; end typedefs
And normal blitz arrays ARE dynamic, you just redim them. But field arrays are not dynamic, and must have a known size at compile time. So
;BROKEN CODE
global typesize = 20
type mytype
field thefield[typesize]
end type
;END BROKEN CODE
Will not work.
But
const typesize = 20
type mytype
field thefield[typesize]
end type
Will work since typesize is const, and is therefore known at compile time.
