Mortar Accuracy

Incompatible with Combat Extended mod!

~~NEW Added option for leading moving targets, translations, and shooting mortars learns Shooting/Intellectual skill

Tired of never using those Antigrain warheads because a Colonist is going to miss wildly? Now your colonists can put their science skills to use and calculate accurate mortar shots!

Github version here[github.com]

A collection of options to make mortars more/less accurate. Customizable in the Mod Settings menu. These changes affect all mortar shots, including enemy mortars. Changes include:
  • Lead moving targets!
  • Weather: Mortar accuracy is affected by weather and time of day (in vanilla, mortar shots rarely are affected by weather)
  • Colonist Skill: Mortar accuracy is affected by colonist Intellectual and/or Shooting skill (in vanilla, skill makes no difference)
  • Cover Miss Chance Removed: Mortars no longer have a chance to miss due to cover surrounding the target (in vanilla, target's cover causes missed shots)
  • Accuracy preview shows the accuracy radius with the current colonist/weather conditions and settings (in Mod Settings can revert to showing blast radius instead)
  • Can customize how much high-skill colonists can improve mortar accuracy, and how much low-skill colonists hurt accuracy
By default, a colonist with maximum skill will improve a mortar's accuracy by 75%. A colonist with no skill will affect a mortar's accuracy by -40% of it's normal value. These values can be changed in Mod Settings (can set all skill-levels to have 100% perfect accuracy if desired)

Saved Games and Compatibility
Can be freely added/removed from saved games. Works with most modded mortars (anything that doesn't require line of sight is likely affected)
Verified/custom support for:
[WD] Expanded Artillery: Accuracy affects new mortars and cannons
More Vanilla Turrets 1.0: Accuracy affects manned rocket turret, manned blast charge turret, and devastator mortar
Kaiser Armory

Known Issues
Vanilla Furniture Extended - Security on Rimworld Unable to place catapult or rocket launcher buildings.
Combat Extended: Incompatible! Patch is unlikely with CE being such a large overhaul. CE does have their own mortar accuracy mechanics though with spotting binoculars
[XND] TE Turret Expansion: This mod also affects mortar accuracy so it is likely that whatever mod is higher in your load order will be overwritten.

99% sure this works in multiplayer, but I have yet to test it (all clients will need the same Mod Settings)

Future Plans
  • Add option to use best of selected skills (Shooting or Intellectual) instead of using average
  • Show UI circle of targeted tile adjusted for leading moving targets
  • Option for Shooting skill to improve mortar reload time
  • Option for AI select best pawn for mortar duty
  • Whatever people suggest that sounds fun

English, Russian, Chinese Simplified, and Spanish (Latin American) supported.

So any idea why the catapult and rocket (turret?) can't be placed when using Vanilla Expanded Security?

@Selmephren There is no hotkey at the moment, but you can toggle the AOE indicator in the Mod Settings page

Is there a hotkey or something to switch between showing the shells area of effect and the targeting area?

I have found a mod that seems to throw an error when loaded with this mod. It seems to not be able to patch the mortars/cannons in the Not Only just a cannon mod. Below is the msg that appears in my logs whenever i load the game with both mods enabled.

[Not Only just a cannon] Patch operation Verse.PatchOperationFindMod(Mortar Accuracy) failed

This mod is causing VFE: Security to throw null pointers while placing a rocket turret since 1.1. Is there anything you can do?

If both skills are selected, they are averaged together e.g. Intellect 20 + Shooting 10 = a colonist who has a mortar skill of 15. Also, the XP awarded for operating the mortar is split between the two skills.

hi i think it depends on mod settings

Does shooting and intellect affect accuracy at the same time or does the higher of the two skills dominate?

@LarryLazerSkates Main Menu > Options > Mod Settings > Mortar Accuracy will have several checkboxes/sliders available to customize.

@Vaeringjar Likely, yes. To verify if this mod affects accuracy for a specific launcher, select the launcher and attempt to Set Forced Target. Check what the accuracy radius preview looks like. Then, assign a Colonist to the launcher. Set Forced Target again and see if the accuracy radius has been affected. If it has changed, then this mod is affecting the accuracy.

@NorthRaider123 I have updated the incompatible list. Mortar Accuracy is unfortunately incompatible with Vanilla Furniture Extended - Security regardless of what version it is.

Hi! Where do I find where I can adjust the mod settings?
