Why the tanks go through landscape and do not stop on it !!??
where is the problem ?
The way it looks, I do not think it is falling through the world, but rather getting launched somewhere. Can you depossess while the game is running, find the tank in the world outliner, and confirm it is falling?
Ah, now that is interesting. Is there anything notable in the Output Log? Window -> Developer Tools in the Log section.

Those are the interesting ones. I think this might be a collision-related issue, since there have been a fair amount of those in the development of this game.
What happens if you turn physics off for the tank? Assuming physics is on for it.
I suspect your tanks arenāt falling through the terrain but instead are going super fast and fly off into the sunset at great speed. Log their movement speed and if thatās the case you may want to clamp it.
I think that is the problem ( the tank move very fast ) because of this code 
Force = Body->GetMass() * Body->GetForwardVector() * 10000 * 1000;
The solution is very simple
Force = Body->GetMass() * Body->GetForwardVector() * 10;
But unfortunately, i faced one another issue where :
1- The missile hit some parts of landscape and some other parts go through
2- The strange thing is, sometimes the missile hits the ground and doesnāt explode but bounces in different directions.
How can i solve these problems 
?
Look at that in the next video
Perhaps itās a similar issue? Itās going too fast. Though the second video looks as if itās just too far away.
But at some parts of ground it is working successfully ?
Really i donāt think there is something strange in my code like the problem above !!
Do you have any suggestion Mr @DanM ?
How did you send me your project last time? I might need to take a look again.
Error Packaging !!
Zip Project Task (Windows): RunUAT.bat ERROR: Visual studio and/or AutomationTool.csproj was not found, nor was Engine\Binaries\DotNET\AutomationTool.exe. Canāt run the automation tool.
UATHelper: Zip Project Task (Windows): BUILD FAILED
Is there another way ?
Verify your engine or just manually zip up the files (donāt include Binaries or Intermediate)
I tried more and more but nothing to do just Zip fire 500MG and upload into Google Drive
Itās exactly as I said. Itās going too fast, I reduced the acceleration and it works fine.

Thanks @DanM a lot but i donāt think only the acceleration is the main problem.
Look to my video
I reduced the acceleration but the problem still existing yet.
Sometimes it is working correctly and other not, i donāt know why does this is out of control status !!
I still searching the solution for that in this and other communities and finding that many suffer the same problem like me.
What value did you use? Using 100 seems mostly fine, only occasional problems shooting at the ground about a metre away.
Ok Mr @DanM like you, now iām using 100 for acceleration but it seems super slow and i think is that illogical in real world which the missiles should be very fast. [Look to my video next]
In other worlds why should i control and reduce the speed to solve this problem !! Is there other solution to overcome that ā¦
100 is definitely not that slow on my end. Though I am still encoutering it in some circumstances, Iāll look into it a bit more.
Thanks Mr @DanM for your efforts and iām waiting the new.
But i have new question please !!
I made a little bit updates to my code to be like this:
void AMissileActor::ReGuidingMissile(float DeltaTime)
{
if(LauncherPlayerController->Hit.GetActor() != this)
{
FVector OUT Direction;
FVector TargetLocation = LauncherPlayerController->Hit.Location;
FVector MissileLocation = FrontPartOfMissile->GetComponentLocation();
Direction = (TargetLocation - MissileLocation).GetSafeNormal();
DrawDebugLine(GetWorld(), MissileLocation, MissileLocation + Direction * 100000, FColor::Green, false, 0, 0, 5);
}
}
I used DrawDebugLine to represent the direction of the missile so the first missile i fired worked good but the second one make illogical green line of directions Why !!? for more look to video
