How to set up projectile collision

Hey everyone i’ve followed this tutorial(link text) on creating a custom projectile.i’ve made a change and decided to use a sphere instead of a flaming chair which he uses :).I have no problem creating and spawning the projectile but i can’t seem to get it to collide and bounce of anything.I’ve also checked this tutorial(link text) on setting up collision but still haven’t managed to get it to work.Can anyone tell me what i’m doing wrong ?I can also show my settings if needed.Thanks for the help in advance

cant really give much help based on the information provided thus far. we have no idea what you currently have setup for collision settings and script. also what do you mean bounce off things? did you want it to be like the fps template projectile? is your sphere set as the root component or do you still have a scene component as root?

Hey sorry here is what i did: 1. Created a blueprint actor .2.Created a sphere component inside the blueprint and added projectile movement.On the sphere component i clicked on the static mesh and added simple sphere collision i then scrolled down in the details and changed the collision complexity to use simple collision as complex. Do i need to change anything else for it to collide with other objects? Oh and i wanted to add the bounce just to see if it collided which it didn’t.Here are also pictures of the settings

two things to try.

first try making your sphere the root component. if the projectile movement is moving the scene root which doesnt have collision then its also moving the children of that component and for some reason it ignores their collision settings.

second try changing your collision complexity to toi either project default or use complex as simple. this will either use the simple for collisions as is the default or if the sphere doesnt have simple collision it will use the mesh’s geometry as collision which is using the complex.

So i set it to root and tried both changes. Didn’t help

hmmm i just made my own version of this that worked so there must be another setting in collision that you changed. i just noticed that in you collision theres a setting that says customized collision that doesnt exist in my version. not sure what that does but im guessing it means that the settings have been altered. make sure that your collision is set to block all in every category, set collision enabled to query and static, and make sure your object type is world static. does your projectile collide with anything in your scene? static or dynamic?

heres the collision settings i have and it works.

Actually your first suggestion to change the sphere to root might have fixed it but i forogot i deleted the simple collision from the bullet in the static mesh and that’s why it didn’t work at first.Now it does thanks a lot :slight_smile:
