I try to implement the pawn navigation to the player in my game. When I tried that in BP site, it worked perfectly, but I try to transform that in C++ code. And I got a kind of wird error. Befor this I faced another error but I find the NavigationSystem was changed a bit in my ue version, but I figured out problem by changing to UNavigationSystemV1. It might be interfering with my class?

NavPath pointer it gave me the error.

Here is the error list:

Currently I have a class for my character like so:

.h

I'm new to Unreal Engine. I'm trying to create a basic game where you control a ball and roll around, trying not to fall out of a tube and stuff. My ball looks like this:

PlayerBall.h

In a cpp file, my use of:

I am using Unreal Engine version 4.25. I have created an actor and placed it on a blank template. The actor is visible in the editor but becomes invisible once the play button is hit. I am trying to move the object in circles with my code.

Here's the code:

MyActor.cpp

I am Xavier ten Hove and I am very new with C++ and Unreal Engine 4.

I am creating a pickup script with a box collider and I have an anyoning error with my pick up script. error C2248: 'UPrimitiveComponent::bGenerateOverlapEvents': cannot access private member declared in class 'UPrimitiveComponent':

I am really trying to fix this one but I cant find the fix what I need!

Here is my header code:

I'm creating a third person laser tag shooter thing for fun and I'm having difficulty creating my weapon hierarchy. My main problem is my editor is crashing from an access error from some errors from pointers in my code and I don't understand pointers enough to be able to figure this out myself.

I'm trying to add a weapon to my default pawn ALTPlayer. I'm doing this by using TSubclassOf to ensure I can only attach children of ALTWeapon to my character

If it helps my explanation, current hierarchy is:

APawn->ALTWeapon->ALaserGun

... and I'm planning on adding a bunch more classes with ALTWeapon as their parent. I'm hoping this will make my code organized and easier to code different functionality for each weapon.

With that in mind, I'll start with my ALTPlayer.h file. Here I declare WeaponClass as my subclass variable

I'm trying to create a laser beam actor that spawns when the player presses the "Fire" action mapping. I can't get TSubclassOf<> to work so that I can spawn the actor that creates the laser. I can declare the variable and compile the project, but I can't seem to use the template anywhere else in the project because the variable isn't initialized??? I'll include my code to help explain what's happening.

Here is my LaserTagCharacter.h file. I've declared the LaserClass variable and I can compile this code with no problems.

I've created a LaunchPad actor C++ class which is compiled of a Cube static mesh component and a UBox component. As of now, once the character overlaps the hit box it triggers whatever is inside the ALaunchPad::OnBoxBeginOverlap. I am current trying to tell that when the character overlaps the UBox launch them in the air similair to the Blueprints 'LaunchCharacter' node.
