How To Drag And Drop Items In Pygame

In this video I will explain how to drag and drop items in pygame.
I'll show how to use the event handler to select a box and move it around with the mouse.
For the full source code and step by step explanation head over to my website: www.codingwithr...

Hey sorry I'm late! I'm glad I could find your tutorial because it's actually exactly what I am looking for. Whenever I searched drag and drop, it would only give me tutorials on making things "snappy" rather than leaving the item where your mouse is on the screen.

Excellent example -- short, to the point, very clear.

Cannot find reference 'collidepoint' in 'Surface | SurfaceType' Cannot find reference 'move_ip' in 'Surface | SurfaceType' i get these errors and idk why. the pygame window opens, but then i click on anything it crashes D:

[@KIRANTS-s5w]

Hello. What if i only want to move them using the corners only? Thank you in advance

[@Formulaah]

Hey Russ! Could you tell me how to make it when MOUSEBUTTONUP the boxes have gravity and they fall to a surface? So they have gravity in general and you can pick them up and when MOUSEBUTTONUP they fall again.

[@CodingWithRuss]

Hello, yes sure, I have a couple videos explaining how to add gravity. This one should help: kzbin.info/www/bejne/qWaWhWmbh8mNptk

[@Formulaah]

@@CodingWithRuss Thanks man! You’re my favorite KZbinr!! ❤❤

[@alexanderwolter]

Thanks for the video. In my version the boxes appear one after another every time when I click to close the window. I wanted all boxes to appear directly at the beginning. Can anyone help and tell me what I did wrong? Thanks in advance

[@fuzzy-02]

Hey man, what if I have a grid of hundreds of boxes. Wouldn't this be terribly slow to check if my mouse is clicking on which box

[@CodingWithRuss]

For a grid based game I would use a different approach and actually split the screen into a grid. Then you can check the mouse coordinates and work out where on the grid your mouse is. That narrows down the collision checks that you have to do because you would be looking inside a specific grid square at that point.

just (well nearly) what I was looking for, I want to only drag in X and Y but struggling to do so. Any ideas? (btw, nearly finished your Udemy platformer!)

[@CodingWithRuss]

Hi, sure I can try to help, what do you mean by only drag in X and Y though? Do you want to make it so a box is restricted to only move left and right or up and down? Like menu sliders? The event.rel variable is used to track mouse motion in x and y coordinates, but if you wanted to only move in the X axis for example then you could modify the move code to be move_ip(event.rel[0], 0). This way it would move along the x axis but not the y axis. You can do the same thing for vertical movement by swapping those round and using event.rel[1].

Love your videos, man! How do I go about moving a .png that I've got on the screen?

[@CodingWithRuss]

You can still use a rectangle for working out positions, but instead of actually drawing the rectangle, you can blit an image at the rectangle's x and y coordinates

[@-_Nuke_-]

is there a tutorial for making the boxes transparent so that you can look through them?

[@dohg678]

You want to change the colour from “purple” to a tuple e.g. (150, 0, 150, 100). The first 3 values are the colour values, which should give a purple colour. The last value is how opaque you want it to be. Hope that helps :)

[@lightingzr]

if we want to, how can we change the number of blocks?

[@CodingWithRuss]

The for loop for i in range(5) determines how many blocks you make. So you can change the number 5 to make as many as you need

[@justin7oo994]

Could you please make a tutorial on tile collisions for platformers ?
