Hi everyone, As mentioned in last weeks diary, I wanted to go a little more into detail with a few of the changes modders can look forward to in 1.3.3. Tech trees A part of HOI4 we've often seen modded are the technology trees, specifically adding trees that are unique to one nation. This has so far been achieved with a clever little trick, where the first technology in a tree only is available to a certain nation. This does achieve the goal, but it also means all trees are visible, even though the player can never research them. In 1.3.3 we've added dynamic technology folders, which hides and locks any technology in the folder that does not meet the trigger. I've taken a book out of my click bait add and prepared a little before and after sample using BICE as an example of how the new mod feature looks.

Obviously they could chose to remove all the original folders and replace with country unique ones, but that's up to the BICE guys. This does technically work with any trigger, but I recommend primarily using it for tags. Enabling during the game and and keeping it enabled for the rest of the game should not be a problem. Industry One of our focuses for 1.3.3 is to improve industrial balance. We will talk more about that in the future (when its actually done :D) but this has led to some new features modders have requested as well. Its now possible to separate the industrial bonuses between factories and dockyards for example (helpful for balancing concentrated vs dispersed industry also) as well as now being able to control the max number of factories assignable to production lines (some mods like to limit the max for naval construction for example so you produce more in parallel rather than serially) but so far this was only possible by limiting UI for player. Now it can be set separately for military, civilian and naval lines. Change state names

Changing victory point names Of course modders have also wanted to be able to change names of cities, and now you can!
More is more! These new features will amaze you. I can't believe no 5 [quote] Apologies if some have already been mentioned =) -Added trigger to technology folders. Will hide tab and disable research for techs if trigger is not met. -Split up factory modifier into a new industrial_capacity_dockyard so dockyards get their own progression -Added local_non_core_manpower state modifier -Added effect add_state_modifier -Added an on action for on_annex. Fired from both effect and peaceconference. -Fixed on_civil_war_end having a fixed random seed -Added has_country_leader trigger -The AI is no longer quite as emotionally attached to modded ideas. Will now consider changing non-hardcoded ideas if the ai_will_do value is higher than the existing idea. -Added new ai strategy "template_xp_reserve" that lets you modify how much AI wants to burn or not burn its xp for division design -Added proper error handling when reading scripted ai strategies -Added can_join_factions rule -Added trigger has_tech_bonus. Works with specific technology or category -Added has_resources_amount trigger -Added on_startup to onactions -Added count_triggers ( same as calc_true_if on other projects ) -Added set_state_category -Added set_state_name [/quote] The rest of the team are squashing bugs, working on late game performance and as always improving the AI.
