Deactivating tech

[safetoss]

Hello!

I'm trying to make a map with a techtree such that when you research one upgrade, some other upgrades will beome unavailable.
But there is no "prevented by" option among the techtree ones in the object editor.

How do I do it? Does it have to be done by triggers?
I would be grateful for advice.

I do not know, but I am currently working on a map where I want to limit the number of structures of a type that one player can make. To do that, I made it so that when a player finishes construction of the building, all of the workers are replaced with workers that cannot build that structure. Maybe you can do the same sort of thing if there are no better solutions.

There is no way you can do this with the object editor data. One possibility would be to deactivate certain updates for a player after you have researched certain others. Thats failry simple.

Event
 A unit finishes a research
Condition
 Research == SOME_UPGRADE
Action
 Player - disable SOME_OTHER_UPGRADE for owner of Triggering Unit

But it wouldnt look too nice since the button will just disappear and not be grayed out as if it would be if you just dont have the requirements.
However, this would be fairly hard to pull off, best bet to use dummy units somewhere placed on the map, these dummy units are the requirement for the tech, and when the other tech has been researched you remove the dummy units. But units take quite an ammount of memory so it would be kind of a waste.

I do not know if you helped him, but you certainly helped me, lol.

If you intend to make other upgrades unresearchable, you could manipulate the requirements. Create default dummy units that are requirements for your upgrades, and leave them on the map for players. Then remove those units after the upgrade is researched, and you can no longer research other upgrades.

Thanks for the help

I'm not sure if this will work because I haven't tested it myself, but setting the maximum research level to 0 could work.

^no it would not. just use a unit as the tech condition.

A follow up question, I only managed to set research max level 0 for the tech I want to disable, and I can't find the 'triggering player' option. Am I doing something wrong?

What I managed to do was:

A unit finishes an upgrade.
(Researched tech type) = SOME_UPGRADE
Set Max Level of OTHER_UPGRADE to 0

 

[safetoss]

I found the triggering player thing now.
But the trigger still doesn't work.
Is it because of the max level to 0 thing?

there's a Techtree - Requirement on every Research, try that

edit: oh nevermind. you want to disable.
