a question about mod weapons data

[napodx]

i want to mod 7.5cm Infanteriegeschütz 18's data to let them fire ememy out of sight, like 60mm Mortar M2. how to do that

[napodx]

well, i get the document and find out the data. but i do not know how to deal with these issues
1 i change the type of 7.5cm Infanteriegeschütz 18 from 9 to 8, and ap/he/h/sm/s from -1 0 0 0 -1 to -1 1 1 1 -1. it works, however, after 22s the gun stops and could not shot the second one with wrong face condition. the only way to shot again is to reset the target.
2 how to change the type of Grille's gun

You want to change them to use indirect fire like a mortar? You will probably have to change the weapon's primary and valid targets to match the other mortars, and the team type and SAI unit for the 7.5cm IG teams in Axsteams to indicate that it is an indirect fire vehicle team too (towed guns are treated as a special type of vehicle by the game engine).
