[Resolved]How do I use my own projectile?

[shandrolis]

Hello there!
This is my first go at modding, and I'm basically trying to make a better (if a little overpowered ) version of the basic grenade, called ' advanced grenade' .
Reason I'm trying to make it, is to easily clear trees
I'm aware there is a Thermite mod for that (or ofcourse the vanilla way, construction robots), but it seemed like a good opportunity to teach myself to to make my own mod.

My problem is that I can't figure out how to use my own projectile.
I can make my custom item throw the basic grenade projectile, just not my own.
Whenever I add "advanced-grenade-projectile" at

Code: Select all

ammo_type =
        {
          category = "capsule",
          target_type = "position",
          action =
          {
            type = "direct",
            action_delivery =
            {
              type = "projectile",
              projectile = "advanced-grenade-projectile",
              starting_speed = 0.6
            }
          }
        }

,
I get the following error:




If someone could help me figure out what I'm doing wrong it'd be greatly appreciated!

have you tried re-ordering the requires list so projectiles loads first?

Still the same error :/

Anyone else have an idea on this? I'm at a loss.

You need one more set of curly brackets in your data.extend call. The function expects a table of prototypes.
And there is no "medium-scorchmark" so it seems. You could extend your own perhaps ? Example in ~\prototypes\entity\demo-remnants.lua

This loads for me:

projectile.lua

Oh my god how did I miss that lol. Thanks!
Anyone got a good IDE for this that tells me when I do stupid stuff like this? ^_^
