List of values you can modify by technologies, buildingai blocking capture ability

[Friedrich123]

Hello,

So I wanted to make an own mod for 0ad, focussing on balancing and palying around with some ideas.
I ran into a problem trying to modify the "UnitMotion/Acceleration" of a unit using the { "value": "UnitMotion/Acceleration", "multiply": 1.25 } in a technology I added, as it didnt change the value of the unit. But the same tech was possible to modify the UnitMotion/WalkSpeed and Attack/Ranged/PrepareTime. So I wonder if there are values that cant be changed with the "modifications" tool or if I just made a mistake.

{
	"genericName": "Steppe Tactics",
	"description": "High manouverability and more practical bows are essential for cavalry archer combat.",
	"cost": {"food": 150,"wood": 200,"metal": 200},
	"requirements": { "tech": "phase_town" },
	"requirementsTooltip": "Unlocked in Town Phase.",
	"icon": "recurved_bow.png",
	"researchTime": 10,
	"autoResearch": false,
	"tooltip": "Cavalry archer acceleration +25% and -30% prepare time.",
	"modifications": [
		{ "value": "UnitMotion/Acceleration", "multiply": 1.25 },
		{ "value": "UnitMotion/WalkSpeed", "multiply": 1.2 },
		{ "value": "Attack/Ranged/PrepareTime", "multiply": 0.70 }
	],
	"affects": ["Cavalry Archer"],
	"soundComplete": "interface/alarm/alarm_upgradearmory.xml"
}

 

 

Another thing I had a problem with is the buildingai. I wanted to make chariots shoot while moving, so I applied the same method used in the siege tower and just set the base arrows to 1. Now the problem is: The modified chariots cant capture buildings, as they have the building flag. Is there another way to implement the same change? I either thought about making an exception for chariots blocking the buildingai or making a bypass at the flag that disallows dealing dmg and moving, although I dont know where Id find that.

See https://gitea.wildfiregames.com/0ad/0ad/wiki/TechModifications for a somewhat up to date list of all things that can be modified via tech. Unitmotion stuff is C++ so sadly you won't easily be able to override the values with techs. (Other than the two in that list)

You should use turrets for this instead of making the chariot use building AI. The feature while integrated in the game is not completely finished though, so expect bugs/issues

@Freagarach implemented it in https://code.wildfiregames.com/D1958

thanks for the fast reply and the list of course. Sadly my c++ isnt very good, but ill look into it maybe
