Access variable in UE4 source code by method of my project - need help

Development Programming & Scripting C++

Hello guys,

I have modified the UE4 method *float FPhysSubstepTask::UpdateTime(float UseDelta) * in PhysSubstep.cpp

I would like now to switch the modification on and off by a method of my own project.
So if there was a bool-variable in the *UpdateTime *method I would like to change the value of that bool from outside.

How can I do that? Can this bool be made global? Can I use a blueprint?

Any ideas how to solve the problem would be very welcome!

Thank you in advance!

There are lots of ways…

Maybe configure a console variable so you can change it while in game?

Also - Looks like that function is already reading UPhysicsSettings. Maybe just add your bool to that?

sounds good that there are alot of ways :slight_smile: I just need one!
You mean I can put my bool in UPhysicsSettings and can access it from the game code?
How can I do that…
Could you please be more specific please?

So you can access it via the global accessor they are using, eg.:

UPhysicsSettings * PhysSetting = UPhysicsSettings::Get();
PhysSetting->MyBool = true;

Be sure to add MyBool to PhysicsSetting.h:

UPROPERTY(config, EditAnywhere, Category = Constants)
bool MyBool;

You will of course have to rebuild the engine after this.

After this, you may even be able to edit it in menu …ProjectSetting…Physics…Constants
