Hi my blueprint seems to be setup right for my turret but when i drag it into the world the mesh spawns super far away from the turret which means the checks aren’t done when i am near the mesh they are only done when i am near the capsule which is invisible. any ideas how to fix this? thank you in advance
Could you show the details panel of the blueprint please?
sure, i’ve also tried creating another turret from the c++ class and had the same issue although strangely it was at a different distance from the mesh
Sorry I missed “The base static mesh component” of that.
sorry, where should that be?
So you have the bug where you can’t see the transform…
Could you try commenting out the UPROPERTY for the BaseMesh, compiling, uncommenting, then compiling again?
I tried, it didn’t seem to change anything the rotation and scale still aren’t showing
is there any other workaround that might work?
You could just set it in BeginPlay
BaseMesh->SetRelativeLocation(FVector(0.f,0.f,-70.f));
i get this C:\GameDev\Tanks\Source\Tanks\Pawns\Turret.cpp(15) : error C2248: ‘AVehicleBase::BaseMesh’: cannot access private member declared in class ‘AVehicleBase’
when trying to do that, i tried moving it the the public area but that didn’t work
BaseMesh would need to be at least protected in order for PawnTank to access it but you can just do that in PawnBase’s BeginPlay.
so that does move it at the start of the game but i get this error Mobility of /Game/Maps/UEDPIE_0_Main.Main:PersistentLevel.BP_Tank_C_19 : Capsule Collider has to be ‘Movable’ if you’d like to move.
over and over again in the log but when i check the capsule collider in BP it is set to moveable
You’re trying to move the capsule instead of the mesh.
i know it says that but the only code i’ve changed is adding BaseMesh->SetRelativeLocation(FVector(0.f, 0.f, -70.f)); so i have no idea why the capsule is moving
Would you mind showing all of your code for all 3 pawn.cpp files?
sure

Can’t see anything wrong with that and after looking more closely at your message.
Main:PersistentLevel.BP_Tank_C_19
That would mean a tank that’s already in the level. If you search for it in the outliner and then look at it’s components you should see that it’s capsule component is static rather than movable.
Thanks. It’s weird I delete that bp then put the same bp out again and that fixed the problem
