Hey @DT_Lotus!
This should work just fine! I’m not sure what the issue is, though. Try this:
Describe what you want to happen
Describe what is happening, especially noting the parts that aren’t matching what you WANT to happen.
Right now your goal vector position is just the target plus 1 meter upwards. Is it not moving in the X and Y? Maybe try a print string before the suggest projectile velocity custom arc and plug in the Target Actor variable to make sure it has a value!
