Formatting a String with three int's

Development Programming & Scripting C++

I am using UnrealEngine and Rider for the C++ side.

Morning all, Hope I can ask this here.

I am following a instructor for a course but cannot get this resolved because its not part of the course.

So here is his original code.

void FInv_LabelNumberFragment::Assimilate(UInv_CompositeBase* Composite) const
{
FInv_InventoryItemFragment::Assimilate(Composite);

if (!MatchesWidgetTag(Composite)) return;

UInv_Leaf_LabeledValue* LabelValue = Cast<UInv_Leaf_LabeledValue>(Composite);
if (!IsValid(LabelValue)) return;

LabelValue->SetText_Label(Text_Label, bCollapseLabel);

FNumberFormattingOptions Options;
Options.MinimumFractionalDigits = MinFractionalDigits;
Options.MaximumFractionalDigits = MaxFractionalDigits;

LabelValue->SetText_Value(FText::AsNumber(Value, &Options), bCollapseValue);
}

it displays a float value called Value in a item description widget. It works no problem.

Now I want to display a 2d6 +3 type of value.

NumberOfDice d TypeOfDice + ExtraDamage.

So this is my code, but cannot figure out to properly write the code.

void FInv_DamageNumberFragment::Assimilate(UInv_CompositeBase* Composite) const
{
FInv_InventoryItemFragment::Assimilate(Composite);
if (!MatchesWidgetTag(Composite)) return;

UInv_Leaf_LabeledValue* LabelValue = Cast<UInv_Leaf_LabeledValue>(Composite);
if (!IsValid(LabelValue)) return;

LabelValue->SetText_Label(Text_Label, bCollapseLabel);

FNumberFormattingOptions Options;

*//LabelValue->SetText_Value(FText::AsNumber(Value, &Options), bCollapseValue);
*
LabelValue->SetText_Value(FText::FromString( FString::Printf(TEXT(“%i d %i + %i”), GetNumberOfDice() , GetTypeOfDice(), GetExtraDamage(), &Options), bCollapseValue));

}

this is the line to fix.

LabelValue->SetText_Value(FText::FromString( FString::Printf(TEXT(“%i d %i + %i”), GetNumberOfDice() , GetTypeOfDice(), GetExtraDamage(), &Options), bCollapseValue));

any help would be great. Been at this for days.

Found this post about using FText::Format on a String Table

In your case, the code (not tested) could be something like this:

int32 Value1 = 1;
int32 Value2 = 2;
int32 Value3 = 3;

FText FormatInput = FText::FromString("{Int1}d{int2} +{int3}"); // 2d6 +3

FFormatNamedArguments Args;
Args.Add("Int1", Value1);
Args.Add("Int2", Value2);
Args.Add("Int3", Value3);
FText FormattedText = FText::Format( FormatInput, Args );

ok how would i fix the last line to set

LabelValue->SetText_Value(FText::FromString(FormatedText, &Options), bCollapseValue);

i have to pass it like to original line of

LabelValue->SetText_Value(FText::AsNumber(Value, &Options), bCollapseValue);

with Replacing Value with FormatedText?

Replace the FText input parameter with FormattedText like so:

LabelValue->SetText_Value(FormattedText, bCollapseValue);

Final code could be something like this:

FText FormatInput = FText::FromString("{DiceCount}d{DiceType} +{ExtraDamage}");

FFormatNamedArguments Args;
Args.Add("DiceCount", GetNumberOfDice());
Args.Add("DiceType", GetTypeOfDice());
Args.Add("ExtraDamage", GetExtraDamage());

FText FormattedText = FText::Format( FormatInput, Args );

LabelValue->SetText_Value(FormattedText, bCollapseValue);

Close but AsNumber needs the first argument as a int or Uint or float.

You don’t need FText::AsNumber() anymore. Replace it with FText::Format() like so:

LabelValue->SetText_Value(FText::Format(FormatInput, Args), bCollapseValue)
