theres a .dbf file in the modpack called product_types.dbf there 2 colums for making a restriction of year to invent thats caninv_yr = the year it is availible to invent
invent_yr = the time it takes with a single level 1 R&D unit to invent it
both colums should have a value to activate the year restriction.
you can also lock the product until up to 2 other products has been invented, that would be in the same file
parent1 and parent2
i.e. if you want to lock Tablet computer until a desktop computer and notebook computer has been invented
you gonna add desktop computer and notebook computer to the parent1 and parent2 column and ya got it.
if you want to make also a dependency on the tech (i.e. touch screen, mobile UI etc) you gonna have to open the
Product_Tech.txt (create it if it doesnt exist)
add the wanted products and the tech you want it to depend and the minimum value and weight in product quality of said tech
please note that the weight of all techs required for a product must have a total sum of 100
if you want techs for desktop comp / notebook computer and tablet computer that would look like
/ the examples are based on the realworld mod product names anything with "/" is just a comment
/ Desktop Computer requiring videostreaming audiostreaming, 2d graphics each at 100 (choose any value the higher the longer
/ to research to get the research points, just choose the value 100 as its a sound number)
[COMPUTER]
VIDEO_ST=100,30
AUDIO_ST=100,30
2D_GFX=100,40
/Notebook requiring Cloud Computing, Solid State Drive, 3d graphics each at 90
[NOTEBOOK]
CLOUD_COMP=90,30
SSD=90,30
3D_GFX=90,50
/Tablet PC requiring Touch screen tech, hand writing recognition, search engine each at 100
[TABLET]
TOUCH_SCR=100,20
HANDWRITE=100,40
SEARCH_EN=100,40
you can choose what ever you like, the techs and its game-intern names you can find in Tech_DBF and you can also change in this .dbf the year restriction when to invent (caninv_yr) and what parent tech is required if any (parent1 / parent2) and their req. tech level (parent1_lv/parent2_lv)
lotsa lotsa numbers to type so gonna take ya couple hours to sort it out
once ya dine ... repack all to get the new .res file with the changes
