I have set up a production map (a grayscale image with splotches all over it) in order to determine what spots in my game are good for resources. It works, but it doesn't. None of the following return anything (they give 0.0) to fort\production. I have tested it however, and fort\production does exist. The readpixel command returns the right number, but the problem seems to lie in the spot where I divide it or multiply it. Why would this be?
function buildFort(x,y,z,name$ = false)
fort.fort = new fort
fortNum = FortNum + 1
if name$ = false
fort\name = "Fort " + fortnum
else
fort\name = name$
endif
fort\x = x
fort\y = terrainheight(terrain,x,z) * 128
fort\z = z
fort\list_drawpage = 1
fort\buildradius = 50
fort\building = 5
;this is to find the fort's production abilities, and shipping bonus
;setbuffer imagebuffer(prodMap)
bittocomponent(readpixel(fort\x,fort\z,imagebuffer(prodMap)))
;divide red (should be the same value as every other colour) by 255
;to get a number from 0 to 1
;fort\Production = production# * 100
;fort\Production# = ((B2Cr + 5) / 255) * 100
fort\Production# = 64 * 100
;picking and drawing stuff
e.entity = new entity
e\entityForm = TradePost
e\parent_id = handle(fort.fort)
building = createcube()
scaleentity building,rand(2,5),rand(2,4),rand(2,5),true
positionentity building,fort\x,fort\y,fort\z,true
TurnEntity building,0,rand(-180,180),0
entitycolor building,80,60,40
entitypickmode building,2
nameentity building,handle(e.entity)
fort\pickID = handle(e.entity)
end function
;the bitTocomponent function
; // Bit (argb) to Component (r,g,b)
Function BitToComponent(ARGB)
B2Cr=ARGB Shr 16 And $FF
B2Cg=ARGB Shr 8 And $FF
B2Cb=ARGB And $FF
End Function
;AARGB! IT DOESN'T WORK!!! (this is fine, I mean the fort function)
Also, is there a way to just read a pixel on an image without using imagebuffer? Because either that method killed my framerate, or something very annoying is running in the background (probably the stupid firewall or virus scanner).
