So this is what I am trying to do. My character is a endless runner game. And I did only game only one button which is jump. "Only one" Now I want my character occasionally has some powerups like speed up or jump higher, or run slower etc. I can add the powerups in the shop menu and tell my users to purchase them via heyzap videos. After they buy a power up can available the entire game until the die, which will happen soon. But i saw only new buttons in the 'Game play' screen can add the power ups and do what I wrote about. Is there way to use these things without adding button. If u played temple run, u will see that, u can select powerups and then start running without selecting the powerups or can. But in BB the powerups button always appead even though the user didnt buy it from the shop section. Any help?
sorry my English is bad but I think u asking about how to add power ups with out using buttons to activit the power up ? Just use action object and place them where U want in the level
