[Urameshi]

I also have a question about 3D

how do you know like how to meet up the the vertices to make the triangles

[yaustar]

Depends on the drawing/rendering mode.

[Urameshi]

what do you mean by a drawing/rendering mode

[yaustar]

From the GU header

#define 	GU_POINTS   (0)
#define 	GU_LINES   (1)
#define 	GU_LINE_STRIP   (2)
#define 	GU_TRIANGLES   (3)
#define 	GU_TRIANGLE_STRIP   (4)
#define 	GU_TRIANGLE_FAN   (5)

Ah, thanks, that pic helps.

In the sample codes I've seen, some people set the fov to 50, and others have used 75. Is one of them more accurate, or is it just a personal prefrence of the programmers?

[Urameshi]

ok now this has been bugging me

wtf is this stackdump error, i keep getting it when i try to run my game

[yaustar]

Depends on the environment it is being used, I can't remember what we use for our game, I think 75 for Widescreen or wide aspects..

[Merick]

if so, then 75 would be better for the psp wouldn't it? Well whatever, I think I got it now, thanks.

[TacticalPenguin]

Some people like to use 45 for 1/8th of a circle, some 50 because its half of 100, it depends on the person

[Urameshi]

here's the exact error

4 [sig] luaplayer 1720 open_stackdumpfile: Dumping stacks trace to luaplayer.exe.stackdump

[moncristo_da_dev]

well can someone simplify the code to only play sprites and blit them?

[emericaska8r]

all this gu and 3d talk may actually get me to look into it now :)

[Grimfate126]

if so, then 75 would be better for the psp wouldn't it? Well whatever, I think I got it now, thanks.

it depends on the game. on a racing game, 75 would be good. but on other games, 75 is overkill.

[Urameshi]

do .gif's work in luaplayer?

[xpack]

Dont think so I think it only supports .png or .jpg and maybe bmp w/ the lrx

[Grimfate126]

do .gif's work in luaplayer?

no, not as of now.

[youresam]

Dont think so I think it only supports .png or .jpg and maybe bmp w/ the lrx

or bmplib I made.

[Urameshi]

no wonder the game im tryin to use keeps crashing, cause of the .gif

[moncristo_da_dev]

lol, im trying to get animlib to work, i have not changed anything in animlib or added anything and i have this on my lua file to test it out

dofile("animLib.lua")
--animations
walkright = SS.new("jackrunright", "png", 64, 48, "images/jack/")

while true do
     walkright:blit(0,0,100)
     screen.waitVblankStart()
     screen.flip()
end

like i said i have not added anything to the animlib code or changed anything, but when i start up my lua file with the code above, an error message posp up saying:

error: animLib.lua:27: '<eof>' expected near 'end'

[xpack]

Well what line is 27

[Urameshi]

i think it means delete the end near line 27

[moncristo_da_dev]

ya, in the line 27 it says end and before that on line 26, it's just a blank line
-= Double Post =-
think i should delete the blank line

[xpack]

Well then you probably have an extra 'end' in your file

[moncristo_da_dev]

but before the blank line, there is no other end
-= Double Post =-
lines 25, 26, 27:

25:return c
26:
27:end

[xpack]

Well that may be it there, that end must be there and it's not suppose to ... print all your code and point out line 27

[moncristo_da_dev]

ok, i solved that problem, now it says eof expected near function on line 33

[xpack]

Whats the function???

[TacticalPenguin]

Urameshi, why'd you ask here when I told you 20 minutes earlier in a PM that gif's are not compatible with luaplayer?

[moncristo_da_dev]

man, did this ever happen to you guys when you started using animlib?
-= Double Post =-
starting with line 25:

25:-- BLIT ANIMATION --

function ANIM:blit(x, y, delay)

self.interval = delay
self.timer:start()

if self.timer:time() >= self.interval then
33: self.currentFrame = self.currentFrame + 1
self.timer:reset()
end

[Urameshi]

Urameshi, why'd you ask here when I told you 20 minutes earlier in a PM that gif's are not compatible with luaplayer?

no you didnt, you told me that either the code was wrong, or it was because luaplayer windows sucked
