Hey All,
I'm a game dev student that is working with SFML(2.4.2) for the first time.
Context:
I'm making a simple map editor for a terrible frogger clone, that runs off of a 2D array of a class I created, where SFML is drawing a bunch of sprites to fill the screen. I've made another sprite of a crocodile that I need to layer on the top of my water sprites.
So my program is actually working fine logic wise. I have no errors or anything and the crocodile sprites are being drawn in the right location on the right tiles only and everything, but they're layered behind my first set of sprites, so normally they are invisible to the user.
I've made my other layer of sprites partially transparent to make sure of this. I've messed around with changing the draw order of my sprites among other things with no success.
Any advice on how I can get my crocodile sprite to draw over the top of my tile map? I'm open to everything (please be gentle though I only started working with SFML/c++ about 6 weeks ago I'm not too good at this yet)
If you want to take a look at the whole C++ project heres a google drive link (no viruses i promise, though google may disagree):
