How do I kill my the player if it lands on a certain block

Question

So my problem is that when I land on block 3 or lava my player doesn't die and I have tried if tile == '3': display.blit and the stuff that goes inside it but on the lines after I put pygame.quit and on the next line sys.exit it says

DeprecationWarning: an integer is required (got type float). Implicit conversion to integers using int is deprecated, and may be removed in a future version of Python. obj_rect = pygame.Rect(background_object[1][0] - scroll[0] * background_object[0],

So what is my solution and if you need my map here it is. Little bit of explaining. 0 being air, 1 being dirt, 2 being grass, and 3 being lava. Please look at the map in full screen or it will look all messed up.

[] 2 idle is in the idle set in the player animations folder and run is in the run set in the player animations folder. sorry if there are small but I would like the lava to be big and because of the deprecation warning the code isn't running and just ends.

The warning just means you are passing floats to the Rect constructor. Pygame can't draw on half pixels so it rounds internally, wasting CPU cycles.

A quick fix is to convert the parameters to integers. Use int to truncate the decimal portion of the float.

obj_rect = pygame.Rect(int(background_object[1][0] - scroll[0] * background_object[0]),
                       int(background_object[1][1] - scroll[1] * background_object[0]), 
                       int(background_object[1][2]),
                       int(background_object[1][3]))
