a Sphere Trace For Objects works better in 3rd person rather than a line trace. A sphere trace centered on the character mesh with a radius of about 150 is good for picking up objects, opening doors, etc.

[@thegamedevcave]

For sure true!

Everything works as you are presenting for me until I try to manually populate an Inventory in the editor, If I do anything other than run the add rock function to the inventory, the entire array resets.

I am loving this series, it has been super helpful! I am curious how to save the inventory, I have never worked with array's! I have a bunch of other variables saving, but can't seem to get the Arrays to work the same way!

[@thegamedevcave]

On your save data class you should just be able to add arrays as a variable and then when saving you simple get the array you want to save, use a for each loop and add every individual entry to the save data array that way.

@@thegamedevcave Thank you so much! I also had to add a variable on the inventory comp that would check if the inventory had been built, and if so don't run the Constructor script! So far so good!!

Great one man, Thank you. I have a problem though. The line trace never hits any bp_world item. it hits everything but!! I don't get it. I have collisions on and everything. what did I do wrong

[@thegamedevcave]

hmm strange. maybe your item's mesh collision channels are set to something weird?

[@Melfar]

@@thegamedevcave there is nothing special about it, just like any other object. the thing is, the line trace hits everything in the scene except the any child of BP_WorldItem. I am going nuts man

[@Atl3m]

Good one like always 😊 thank you

[@thegamedevcave]

You're welcome 😊
