2D aiming on mobile

Question

I'm currently making a game, Myplayer shoot bullets and to assist him I create a sprite in the front of the player to help him sinep well and this sprite follow mouse position, now I'm trying to export my game to android platform, So I'm stuck here, When playing the game using mobile, How can the player aim now???

Comments

Unless I misunderstood the question.

Mouseposition = phone touch position

Yes you're right, but then I can't aim on the phone because on pc the hole screen is for aiming but on the phone it must be a small place like most of the games half of the screen is for movement and the other half is for aiming , so i can't use the hole phone screen for aiming

Has the question already been answered? If compatible with your game, just use a virtual controller/joystick. :)
