I want to find out what function is calling another function. I will try my best to explain myself.
For example, I would like to know which function is calling "function A" and I need to press a key in-game to let that function call "function A". However, the problem is that function B, is constantly calling function A, so as soon as I toggle a breakpoint, the game freezes and I have no chance to press the key in-game. As a result, it is impossible for me to know which function is calling "function A" when I press the key in-game (coz the game is already frozen because the other irrelevant function is constantly calling function A and triggers the breakpoint).
Is there a way to not freeze the game while using a toggle point? Thanks a lot.

Right click on the break point -> Set/Change break condition

Or maybe Ultimap is worth a look (is hard to tell just by your explanation, maybe you have some screenshots?)
