How to Track the Mouse Position in PyGame! (Python GUI Tutorial)

what's up you guys welcome back to the channel in today's video i'm going to show you how to locate and use the mouse position inside of the pi game module using python [Music] so there are a ton of games that you might want to make that need to have the mouse position known to to use your game you might want this for buttons or you might want this for like point-and-click shooters in any case we're going to set this up pretty quickly so i'm going to kind of roll through setting up the bare minimum to get a pie game screen together so you need to import pi game if you don't have it installed run pip and install pi game and then do pygame dot init set up a width and a height for your screen i'm just going to use 500 500 because it's pretty easy as a default choose a frame rate for your game 60 is very standard set up a timer to actually run the game at that frame rate so pygame.time.clock and then set up the screen to use the height and width that you made so pygame.display dot set mode and then width comma height just like that okay now just uh choose a variable to be your running variable and i'm just going to call mine run set equal to true to start and then say wall run so while we're running we're going to do all this stuff every iteration of the game so let's just start by uh filling the screen with white and again all i'm doing and the reason i'm not explaining this a ton is i am setting up the bare minimum to get a pie game window to open up so that we can talk about the real meat of the game but it's important that you know how we got there so we're just going to say timer.tick at the frame rate which means run this code 60 times per second and then we need to handle some exit conditions so we don't have an infinite loop and so we'll say for event in pygame dot event dot get if event dot type is equal to pygame dot quit all caps just like that then we want to set run equal to false pi game dot display dot flip so that's drawing everything onto the screen and then pygame dot quit just like that so if i run this we get just this plain 500 pixel by 500 pixel white rectangle just like this and that's all we're gonna do for this tutorial so that i can show you guys now how to get the mouse position and it's really easy because pygame has a built-in mouse module so if we have this mouse position variable that we want to populate and let's say we want keep wherever the mouse currently is in this mouse position variable it's dot mouse dot get pause like that and um that's literally it to get the mouse position so let me just print onto the screen the mouse position variable so now i'm gonna run the code and you're gonna see in the terminal in the bottom i'll try to zoom in make this a little bigger you'll see in the terminal on the bottom now if i go oop i gotta get to the bottom of this program oh boy that was a stupid way of doing this so now if i run this code you're going to see in the bottom of the screen there whenever i move this mouse we get an x and y coordinate and it's all relative to our pi game window so i'm up near the top left and we're getting really small numbers i move right and that first coordinate updates because that's the x coordinate i move down and that second coordinate is increasing because that's the y-coordinate so that's all we need for getting the mouse position out of our game now let's say you wanted to use that in the game so pygame.draw let's just put a circle on the screen let's make it red so it's really easy to see and for x and y coordinate we're just going to give it mouse position and we're going to make it a radius 10 mouse now if we run this you're going to see as long as the mouse is on the screen there's this red circle that follows us around so this is super useful if you want like a character that's always pointing or looking at the mouse it's also useful if you want like a point and click a point and shoot kind of game and then obviously for buttons it's really useful because you need to know where the mouse is so this is a really easy way to constantly be checking the mouse position last thing i'll talk about in this video just because it is related in that pie game.mouse package there's this get pressed as well and it's checking the three buttons so i'm gonna show this i'm gonna print pygame.mouse.getpressed in the bottom of the screen and i'm gonna disable this printing the mouse position so you guys can see um so if you can see the bottom of the screen i'll try to make this big but i've gotta get to the bottom of my terminal there we go i'm gonna click the left mouse uh position in my game and you'll see the the first uh box there goes to true now i'm gonna click the scroll wheel the middle button of my mouse and the middle one goes to true and then i'm gonna click the right one and go to it goes to true so if you wanted to check okay where is the mouse and is the left button clicked then you would have this variable like left clicked is equal to pygame dot mouse dot get pressed oop get pressed and just like that but then you would say okay zero and that's the left click button so that's how you would check if the left had been clicked or not and i think i'm going to leave this tutorial here i want to keep this one short and simple i don't want to get it too jumbled with other concepts i hope this is what you were looking for if you searched for basically how to do these types of concepts feel free to check out the channel for tons more python and pygame tutorials let me know in the comments if you had any questions or what you'd like to see in a future video thanks so much for checking out the channel and as always good luck with your code and thanks for watching thanks bye
