setText perfomance issue

hgvyas123

playArea.myScore:setText("Score :- "..myTravelDistance)

the above line is dropping my games fps by atleast 30 - 40% and game looks very very choppy. i am using ttf font. the game is really very heavy loaded for my lg optimus p500 [but it runs very smooth when i comment this line] and i am using 30 fps setting

i dont know wheather using bitmap font will help or not i will try this but thought i should have to mention this over here

Thnx

Thats really interesting, but I have a game where I update score on every enterframe (just to keep effect of increasing score) and have no such problem. Also testing on LG P500 but only with 60 FPS.

i am also updating the score in enterFrame might be mine is more loaded or because i am using 30 fps

actually as it is in development i had still not put the lower resolution graphics only on graphics for the size of 640x960 and hence the game is too much loaded but as i said previously it runs very smooth if i comment that line

Oops, my bad. You are right. I had the same issue, I was always adding 10 points till reached the needed some. now I rewrote it it to add full power of 10 points.
Meaning If I need to add 1000 points I add 1000 points.
If I need to add 900 points I add 9 frames by 100 points, etc. Still has a little cool increase effect and does not seem to slow down the game.

hgvyas123

that's cool

I remember @atilim mentioned that using Bitmap font is faster for changing Text. While TTFont is faster at loading but slower for changing Text.

@chang

yup i know about bitmap font however still not given that a try there a also one method by @techdojo somewhat similar to settextureregion (?) but not tried that also

Hi,

How about adding a function like buildCache() to TTFont class like:

local font = TTFont.new("arial.ttf", 20) font:buildCache(" .,:;!?()&/-0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz")   local text = TextField.new(font, "hello gideros")

So that it can behave as bitmap fonts and practically make Gideros Font Creator and Font class unuseful.

hgvyas123

that would be the excellent

@atilim, buildCache is a user defined function, or will it be available in the newer version of Gideros Studio??

ar2rsawseen

@OZApps I think @atilim meant he would add it and it would be awesome

hgvyas123

does this hack work ?

local text = TextField.new(font, "0123456789abcdef.....")
text:setAlpha(0.01) -- or putting it behind the bg
self:addChild(text)

sorry can't test it currently as it will happen in my p500 and i dont have it currently my brother uffff..........

atilim

I think it's not that hard to implement. I hope it'll be available with the upcoming releases.

atilim

@hgvyas123 nope it won't work currently there isn't any internal caching.

better to call buildCache(" .,:;!?()&/-0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz") as default in the init function as input such a long string is painful.

@alexzheng but then firstly, some specific characters as unicode ones or special characters won't be cached
secondly, if you don't need to change the text, you don't need the cache, it will only consume memory without ever doing anything

Exactly!
