Hello all, new to ue4.
I have a simple projectile blueprint, bare bones, and what I want to do is change it’s settings in game. For example, if you run through a triggerbox, the initial and max speed will be reduced. I was trying to do a cast to the projectile blueprint, but I couldn’t figure out what object type it was. Any help would be greatly appreciated 
if youre casting, you obv have to cast to the object type the projectile is. if your blueprint projectile is called BP_Projectile you cast for BP_Projectile and then you can drag out the nod and address the projectile movement component and change the values
Get a reference to the projectile, call the projectile movement component and you should be able to alter the variables inside.
