How to make conquest game mode

how to make conquest game mode like battlefield3

player should capture 2 or 3 tower to finsh the game

For making the capture areas (point A, point B, etc.) you could make a collision box around the area, and give players an onBeginOverlapEvent and onEndOverlapEvent function that triggers depending on the status of the point.

Okay thx but i need a ui bp for filling a pogress bar after i finsh the tower activate a particle system
