TrueType Fonts issues

OZApps · March 2014

I have faced this issue more times than ever so not 100% sure what the reason for this is.

The Problem:
A project uses a True Type Font and is added to the project via add existing file. The when I hit run to test the project in the player, randomly it spawns an error

myTrueType.ttf: No such file or directory.

while the font and everything else is in place. This in my opinion could be an error dues to memory leaks or something similar. In my project I am creating a lot of TTFont objects at different sizes.

This is a bit of a concern, so could you please let me know why this happens and how to fix that?

Interesting
it is possible that ttf file handler is not properly closed and you run out of handlers and something like that.
Will get it to Atilim to check

What is that ttf file handler and how do you close it? No mention or details in the documentation...

When this project is compiled and run on the XCode simulator, is this normal?? I know that the Font is because of the floating point (scaled value) but the black background is beyond me. When I run the project in the GiderosPlayer on the desktop or the device, it works absolutely perfectly fine, but then on the simulator - this...

BTW: The assets are encrypted if that would make a difference.

Using a newer version of GiderosSDK has fixed the black background issue, need to fix the rounding issue. @Atilim, would it be possible to round off these values in the functions rather than do that at the users end??

The handler was internal, when reading font from file, and based on logs, it should have been fixed already, so you were not using latest Gideros version?

About rounding coordinates, well, there could be a problem, because theoretically, somone might want to set 100x100 logical dimensions and start positioning objects as setX(10.25) ,etc

As in, in my opinion it won't be good to intervene in the usage,
but as all positioning is inherited from Sprite, you can simply overwrite Sprite set/setX/setY/setPosition methods

@ar2rsawseen,

1. TTF not found, irrespective of the version of Gideros, is still present and happens after a couple of runs

2. The Black background is because of the older/newer version exporting the app to xcode. When run in Gideros Player there was absolutely no issue.

The image above looks like it's been censored or information hidden, but that is what the exported project did.

I can override the functions, but the issue is not with the setX setY or setPosition, the problem is with the TTFont.new("fontname.ttf", fontSize) this fontSize has to be an integer, but when scaling for different resolutions, this will not be an integer all the times. So had to fix all the lines where a new font object is created. ALternatively I could also create a Font Object factory function that will fix this issue in one place only.

out of curiousity, how would you override a setPosition without getting into a recursive loop?

ar2rsawseen · March 2014

Ok, will let @atilim look at it

About overriding, my idea was:

Sprite._setPosition = Sprite.setPosition
 
function Sprite:setPosition(x, y)
    self:_setPosition(math.floor(x), math.floor(y))
end

but if you say thats not the case, then dunno

Thanks for that, however I did not override it, instead I have some really bad spaghetti code in there. oh, I made a quick app to demonstrate the Non-Gaming feature of Gideros (as always) this is a simple counter app, that helps you remember things with a counter (upto 4 counters on the screen at one time) hence called reCounter. It is just submitted to Apple for approval and let's see when it does get approved.

Here are some screenshots for the same.
