Here's the deal -- I want my engine to draw four layers of graphics on every field in the dice game environment, so far I successfully managed to make the engine draw two of them, but that was absolutely easy, since those take their render from a single variable.
But, what if I want to take data from a list, and render multiple graphics in a for loop?
I store graphics paths in a list, like this:
Code: Select all
def bgMapData():
Vbg[0] = "images/bg/dgs1_1.jpg"
Vbg[1] = "images/bg/dgs1_1b.png"
Vbg[2] = "images/bg/dgs1_2.jpg"
Vbg[3] = "images/bg/dgs1_2b.png"
Vbg[4] = "images/bg/dgs1_3.jpg"
Vbg[5] = "images/bg/dgs1_3b.png"
Vbg[6] = "images/bg/dgs1_4.jpg"
Vbg[7] = "images/bg/dgs1_5.jpg"
Vbg[8] = "images/bg/dgs1_6.jpg"
Vbg[9] = "images/bg/dgs1_7.jpg"
Vbg[10] = "images/bg/dgs1_8.jpg"
Vbg[11] = "images/bg/dgs1_9.jpg"
Vlib[0] = "images/bg/component0.png"
Vlib[1] = "images/bg/component1.png"Code: Select all
def bgFieldData():
diceGameStage[1].fldEnv[0].layerA = 0
diceGameStage[1].fldEnv[0].layerB = 1
diceGameStage[1].fldEnv[0].layerC[1].decorIndex = 0
diceGameStage[1].fldEnv[0].layerC[1].pos = 20, 20
diceGameStage[1].fldEnv[0].layerC[2].decorIndex = 1
diceGameStage[1].fldEnv[0].layerC[2].pos = 700, 20Code: Select all
def __init__(self):
self.decorIndex = None
self.pos = 0, 0
self.size = 1.0
layerA - Background
layerC - Decorations above background
layerB - Overlay
layerD - Decorations above overlay
However clunky this may seem(and my friend told me that Python lists are slower than other ways), I successfuly adopted this method and it works with non-list rendering, here's how the rendering works:
Code: Select all
class drawLocation(renpy.Displayable):
def __init__(self, loc, fld, **kwargs):
super(drawLocation, self).__init__(**kwargs)
self.loc = loc
self.fld = fld
self.loc_bg = None
self.loc_over = None
def render(self, width, height, st, at):
render = renpy.Render(width, height)
if diceGameStage[self.loc].fldEnv[self.fld].layerA != None:
bgpath = Vbg[diceGameStage[self.loc].fldEnv[self.fld].layerA]
else:
bgpath = None
if diceGameStage[self.loc].fldEnv[self.fld].layerB != None:
ovpath = Vbg[diceGameStage[self.loc].fldEnv[self.fld].layerB]
else:
ovpath = None
if bgpath != None:
self.loc_bg = renpy.displayable(Image(bgpath))
if ovpath != None:
self.loc_over = renpy.displayable(Image(ovpath))
if bgpath != None:
bgimg = renpy.render(self.loc_bg, width, height, st, at)
if ovpath != None:
overlay = renpy.render(self.loc_over, width, height, st, at)
if bgpath != None:
render.blit(bgimg, (0, 0))
if ovpath != None:
render.blit(overlay, (0, 0))
return render
def visit(self):
return [ self.loc_bg, self.loc_over ]Thus, I decided to ask about it here. Whether I'll be suggested a different way of rendering a set of graphics as decorations than using lists, I'd be happy to learn. Other than that, any helpful points as to why this error happens would be greatly appreciated, as I don't have an idea what it could mean, and I got it almost everytime when I was beginning to learn how to render displayables.
Thank you for your time.
