Hey there @Adeel_Yaqoob! For most RTS games, vehicles are almost always just a variation of the base entity class. Depending on the scale of your RTS you may need to run your own system, but for smaller projects using the usual pawns and navmesh shouldn’t be much of an issue. What scale of units would you be looking at? Mobile level like clash of clans or something larger a la starcraft/company of heroes?
