I'm trying, to wrap my head around Touchosc and script based on LUA 5.1.
I have a number of labels, called song0, song1, song2, and so on. I'm trying to set different values in these, using
local text = 'Smoke On The Water'
for i = 1, 2 do
self.children.pager1.children.main.children.song[i].values.text = text
end
but that gives me an error.
:-) I do need help.

Since you haven't provided the actual error, it's difficult to say what the problem is, but if I have to venture a guess, then try replacing ...children.song[i].values... with ...children["song"..i].values.... Since there is no table song, you just need to generate dynamic field names.

I am new to roblox scripting, and I am working on a game. I am trying to make an exploration game with multiple planets. I want the colors on the surfaces of the planets to vary, but I also wish to use smooth terrain, as it is easier to use and looks nice. from reading a bit online, i have figured out i need to use "GetMaterialColor" or "SetMaterialColor". however, "SetMaterialColor", the one i needed specifically, requires two bits of information- the material and the color.
The issue comes from the "Material" part of this, as I have no idea how to make the script recognize what material I want to change. i tried multiple things, including but not limited to:
(grass, #,#,#)
(grass) (#,#,#)
("Grass"), (#,#,#)
("Grass", #,#,#)
or even just (#,#,#), without trying to get a specific material at all
so yeah, I need some help
here is the code:
local function onTouch(hit)
game.Workspace.Terrain:SetMaterialColor
end
script.Parent.Touched:connect(onTouch)
(there should be stuff after SetMaterialColor, that is what i need help with)
If you read the documentation on Terrain:SetMaterialColor(), you'll see that the first argument is a Material type, which is an Enum. So the method expects an Enum (or number to be more accurate), not a string denoting the material.
At the same time the second argument is a Color3, so (#,#,#) isn't apt, using it with the constructor Color3.fromRGB(#,#,#) is. If you are ever confused about what a method returns or expects, try referring to its documentation on https://developer.roblox.com/.
Here's an example of correct usage:
workspace.Terrain:SetMaterialColor(Enum.Material.Grass, Color3.fromRGB(123,123,123))
And ofcourse, Event:Connect() instead of Event:connect()
When I open the print options using AirPrint, I want to make it default to 2 copies and not just 1 copy.
Couldn't find any methods that could change the number of copies. Wondering if anyone has any ideas if this is possible since it seems that this printing option is pretty limited.
So I found my own solution. Basically under the UIPrintInteraction Controller there is a method called printItems. What I did is make an NSArray and put two copies of the object I wanted to print and used that method instead of printItem.
However, since my application used the printFormatter I was unable to use this method since in the IOS developer documentation it says
"If you set this property (printFormatter), UIPrintInteractionController sets the printingItems, printingItem, and printPageRenderer properties to nil. (Only one of these properties can be set for a print job.)"
So what I did was just doubled the html page I was formatting and I trusted that the formatting was correct for it to print two pages.
Another way would be to add the same printFormatter to page 1 and page 2 in a printPageRenderer.
I've read everything I can on forms and such and they never seem to work the way I want them to.
As a work around, I'm trying to pass a series of parameters to my controller via remote: true and javascript. I've got a solid foundation working.
I can't think of a proper way to explain this without getting too crazy, so I'll just explain what I am doing.
Goal-
I have a FlashCard model going. The flash cards each have: Title, lines(7) and a body. The body is represented as the back of the card. The front of the card consists of the title and 7 lines. Each line can be written on individually and optionally centered. The card can be formatted as either read or write. Obviously read is a read-only and write gives you the ability to change whether or not each line is centered, and change/add the text on the title, each line, and the body.
Now. I probably chose a bad way to do this, but it's how I chose to do it. I have an affinity towards arrays so I tend to use those when in doubt.
My flash card model has title:string, line:string as array, and body:text.
The line is formatted as follows: [["",0],["",0],["",0],["",0],["",0],["",0],["",0]]
The strings are the string on each line and the 0's can be either 0 or 1, as false and true- representing whether or not the text on that line is centered.
As far as displaying all of this, I have it working just fine. However- actually saving the data is proving to be a problem. Forms are not working out for me because of the line array/attribute. I don't mind doing the logic myself without the form, but I need a way to pass the data from the text_fields to the controller to save them.
Hopefully that makes sense. If not- I will happily add in the code I have used to get to where I am and more specifically show where I am having problems.
Optimally, I would like to simply pass the strings from multiple text_fields as separate parameters to the controller. If necessary to go back and entirely redo the model, I will do so if it will work as long as I can get the same functionality.
Thanks in advance for the help!
The auto_complete_for dealio from script.aculo.us is great an all, but is there a way for me to selectively disable the fact that it always auto-selects the first item in the list?
The problem is that, if I want to type my own entry that is new, and novel, I don't want the first item in the list to be auto-selected. The reason is because when I TAB out of the field, it selects, and fills the text box with that first item.
I got around that, somewhat, by making the first item in the list the same as what I'm typing, but that's not perfect either, because the auto_complete list doesn't always update with every keystroke, depending on how fast I type. I've tried setting the list refresh rate to the lowest value (1 millisecond) but no go.
What I really want is an option in "auto_complete_for" that doesn't select that first item at all - the same way that Google Instant doesn't automatically select the first suggested search phrase - you have to arrow-down to select one.
Maybe I can do this via an HTML option that I'm missing?
Looking at the source, there doesn't appear to be an option for that, but I bet if you changed line 284 of controls.js to this.index = -1; it would do what you want.
Otherwise, it might be time to look for a different autocomplete widget.
If your requirements are too far away from the available plugin, then I guess there is no point in tinkering around. Its best to write your own JS code.
You might want to consider this: https://github.com/laktek/jQuery-Smart-Auto-Complete
or this : https://github.com/reinh/jquery-autocomplete
I'll add another alternative that works great with Rails 3:
http://github.com/crowdint/rails3-jquery-autocomplete
I recently implemented auto complete for more than a field for Rails 2.0.2.
The plugin I used is:- https://github.com/david-kerins/auto_complete . Not sure if it supports Rails 3.
I have also encountered issues on implementing the above scenario and have posted questions( Implementing auto complete for more than one field in Rails ; Implementing a OnClick kind of functionality and formatting wrt Rails Partial-Views ) on stackoverflow for the same, I have been lucky on getting things working for me based on my requirement.
Kindly refer to these questions, they might have relevance to your requirement.
I dont know what exactly i have to type in title for this ,i tried my best
anyway coming to topic
I am making one acc checker for that purpose ,i am sending user and pass from my bsskinedit1 and bsskinedit2
here is my code
s:='http:\\site.com..premlogin='+bsskinedit.text+'&password='+bsskinedit2.text
but it giving some error ,then i used showmessage whats wrong with it then i came with strange result
see below
observer after 4 & and p combining together and appearing as a some new symbol :(
can any one tell me why its coming like this ?
Your code (where you build the URL) is most likely correct (I guess the above has some typos?!), but when you display the URL in a label for instance, the & character is treated as indicator for an accelerator key.
By Windows design, accelerator keys
enable the user to access a menu
command from the keyboard by pressing
Alt along the appropriate letter,
indicated in your code by the
preceding ampersand (&). The character
after the and sign (&) appears
underlined in the menu.
If you want to display the & character itself, you have to set your string variable to &&.
By placing two ampesands together - you state that the character following the first one is not used as the accelerator - rather you actually want to get it (only one) displayed.
Just use your debugger if you want to see the real value that your string variables have, don't output them to a message box or the like... It may have side effects, as you can see.
Regarding the URL you build: I can't possibly know how it has to be correctly, but at least you should use the right slashes!
s := 'http://site.com...'
(All quotes from delphi.about.com)
In addition to what Mef said, you can use OutputDebugString to add your string to the event log in its raw form, so you don't need to modify it before displaying it. Delphi should capture those strings automatically if you're running from the debugger. If you aren't running it from Delphi you can use DebugView instead, which captures the messages from any running applications.
