[Linux] floats not working?

[Tommek]

I am just starting with aggrors great Saturn-Tutorial and ran into a strange thing.

 

In Tutorial #3 you create a spawn timer and give it a float value. However the leadwerks editor first shows given number, but then round that number. So give it 0.4 after saving etc. its going to be 0.0 what creates a lot of instances in no time.

Giving this the value 1.5 gives you 1, 2.4 give 2 etc.

 

After I change the view the number shown in the editor is 0.0 or 1.0 or 2.0 etc.

 

 

Script.spawnObject = "" --entity "Spawn object"
Script.spawnTime = 0.5 --float "Spawn time"
local timer = 0
function Script:UpdateWorld()
timer = timer + (Time:GetSpeed()/100)
if(timer > self.spawnTime) then
 local newObject = self.spawnObject:Instance()
 newObject:SetPosition(self.entity:GetPosition())
 timer = 0
end
end

 

I've attached a screenshot.

Also if I enter a "Mass" in "Physics" I can only use 1.0, 2.0 etc

 

If I enter 2.5 it gets 2.0, 1.4 -> 1.0, 7.5 -> 7.0 etc

 

So it seems to be a gerneral issue. Dio you need any logs from me?

 

edit: Yes it is in every value field I've entered data so far.

Yes, I can reproduce this issue and (probably) already know what the problem is.

Tommek, am I right that you use a locale that uses comma for decimal separation?

 

If I remove "LC_ALL=C LANG=en_US.UTF-8 %command%" (LANG is optional here, just to make sure Leadwerks doesn't use a half arsed translation by pulling in German strings for default UI elements) from my Steam launch options for Leadwerks, I can reproduce your issue.

There already was a similar issue which was fixed once but it seems to have resurfaced.

Use these launch settings as a workaround until it is fixed.

 

@Josh: Please sanitize the system locale settings when using the editor (and probably the engine as well).

[Tommek]

Thats the trick. I should have known it. Had a similar problem before with a server application.

 

Thanks.

The editor and engine make this call at startup on Linux:

SetLocale 0,"en-US"

 

What else can I do?

Not sure what 0 is

 

But I would suggest setting it for LC_NUMERIC and LC_MONETARY, use the defines as the numeric value is implementation dependent;

http://en.cppreference.com/w/cpp/locale/LC_categories

[Josh]

0 = LC_ALL

[Guppy]

0 = LC_ALL

 

And that is properly the source of your error -

std::cout << "LC_ALL: "<< LC_ALL << std::endl;

yields

LC_ALL: 6

on my system

[Josh]

Is it always that value on Linux?

[Guppy]

Is it always that value on Linux?

It varies with implementation, but I *think* it's always the same for gcc

[Josh]

That explains it. I will try it with 6 and assume this fixes it. It's very hard for me to test this so you will have to let me know.
