ok so its been a while since I looked at zombie tutorial. zombie tutorial shows how to create child class of BP_ThirdPersonShooterAI.? 2. do I have to do all the steps in zombie tutorial? For demon damaging player , I just created a sphere collision , attached it to his claw bone, then on demon bp I did event actor begin overlap, casted to TPP character , then got player get damage event. 3. I guess I’m asking how do I create a child bp from the demon bp? I’m still mr noob here , but not so much anymore.
