i use this code before this crash occurred

void ATower::CheckFireCondition()
{
    if(Tank==nullptr)
    {
        return;
    }

    FHitResult HitResult;
    FVector StartPoint = ProjectileSpawnPoint->GetComponentLocation();
    FVector EndPoint = StartPoint + ProjectileSpawnPoint->GetForwardVector()*FireRange;
    bool LineTrace = GetWorld()->LineTraceSingleByChannel(HitResult, StartPoint, EndPoint, ECC_WorldDynamic);
    DrawDebugLine(GetWorld(),StartPoint,EndPoint,FColor::Red,true,0.f,0.f,5.f);
    
    if(LineTrace)
    {
        UE_LOG(LogTemp,Warning,TEXT("%s"),*(HitResult.GetActor()->GetName()));
    }


if(Cast<ATank>(HitResult.GetActor())==Tank)
{
    if(InFireRange() && Tank->bAlive)   
    {
        Fire();
    }
}
    
}

What code did you add?

Jeetesh · July 11, 2022, 11:46am

 FHitResult HitResult;
    FVector StartPoint = ProjectileSpawnPoint->GetComponentLocation();
    FVector EndPoint = StartPoint + ProjectileSpawnPoint->GetForwardVector()*FireRange;
    bool LineTrace = GetWorld()->LineTraceSingleByChannel(HitResult, StartPoint, EndPoint, ECC_WorldDynamic);
    DrawDebugLine(GetWorld(),StartPoint,EndPoint,FColor::Red,true,0.f,0.f,5.f);
    
    if(LineTrace)
    {
        UE_LOG(LogTemp,Warning,TEXT("%s"),*(HitResult.GetActor()->GetName()));
    }


if(Cast<ATank>(HitResult.GetActor())==Tank)
{

i used this code and after i compiled it played the game it was working(but not the linetracing logic) ,but suddenly the editor crashes then i removed this code and compiled it again it crashes again
i installed editor Symbols for debugging in unreal engine 5 now this is the whole callstack-

Where do you assign Tank? Also could you show your CheckFireCondition function?

Jeetesh · July 11, 2022, 12:13pm

i think after installing ue5 again it’s giving error in every line

DanM · July 11, 2022, 12:30pm

Sorry I meant InFireRange. Also use Tools > Refresh VS Code Project.

Jeetesh · July 11, 2022, 12:41pm

i’m not able to open unreal editor whenever i try to it gives this pop up and close

DanM · July 11, 2022, 12:54pm

Never seen that one before. I suggest you delete your Binaries and Intermediate folders and try again.

Jeetesh · July 11, 2022, 1:11pm

i tried to delete the binary and intermediate files and rebuilt but again a pop show’s

it say’s plugin which has been included into the built has not been turned on , what plugin any idea?

DanM · July 11, 2022, 1:16pm

Are you able to use the workspace in VS Code via

Ctrl + Shift + B > ProjectNameEditor Platform Development Build.

Where ProjectName is the name of your project and Platform is the platform you’re targeting e.g. Win64

Jeetesh · July 11, 2022, 1:19pm

in terminal -

Executing task in folder ToonTanks: Engine\Build\BatchFiles\Build.bat ToonTanksEditor Win64 Development D:\ToonTankProject\ToonTanksProjectSetup_4.22\ToonTanks\ToonTanks.uproject -waitmutex 

The system cannot find the path specified.

DanM · July 11, 2022, 1:32pm

Can you right click the uproject file and Generate the project files? If you can re-run that task afterwards.

Also could you explain what you did in between to get that?

Jeetesh · July 11, 2022, 1:59pm

yes its built now

i wanted to add editor symbol for debugging but it fails to install so i uninstalled the whole editor and reinstalled

on opening the project it sill giving me this message popup and crashes again -

DanM · July 11, 2022, 2:10pm

When does the crash happen?

Jeetesh · July 11, 2022, 2:15pm

at this point crash happened

DanM · July 11, 2022, 4:21pm

I meant, when you start the project? When you press play? etc.

Jeetesh · July 12, 2022, 7:53am

i think after 10 seconds when i pressed play

DanM · July 12, 2022, 10:30am

In that case would you mind sending me your project using the following link?

https://gdev.tv/projectupload

Please use File > Zip Project within Unreal as this will ensure only required files are zipped up and things like the Binaries are excluded.

Jeetesh · July 12, 2022, 11:07am

i want to correct myself, i think you misunderstood the situation
crash happend when i pressed play on first time but now whenever i open the project it crashes without opening the editor
if that won’t open i’m not able to zip up my project
