I am making a 2D top-down shooter game similar to Hotline Miami. I want the background to move as player moves (zoomed in). How do I do this? As of now, I’ve coded only the player movement part without background. Sample pic is shown below (background is bigger, it’s just the zoomed in part): [C…

How do I do that? I’m sorry I’m just a beginner

You need to assign your background position to be some x - some offsetx and some y - some offsety. Where offset y and offsetx is calculated when you press the arrow keys and therefore gets updated. Its the same principle as drag and drop ill post some code later

Something like – def draw(): ... # your x/y variables control the background coordinates image(background_image, x, y) with pushMatrix(): # keep the player in the same place (in the centre of the screen) translate(width/2, height/2) angle = atan2(mouseX-…

wow works nicely! How do I add collision detection with all walls and objects? there are so many of them

Perhaps start another topic for that. There are various approaches … You might look at AABB collision as a starting point.

Is there any way to fade the surrounding background around the player and light it up as player moves? Something like shown in sample image below? [sample.PNG]

I didn’t understand why the coordinates of image in your code is negative (i.e. (player_image, -50, -50, 100, 100)). Can you explain pls. It works, but I want to understand. Also, can you tell me the best and easiest way to place enemies around (non-movable) and after 3 gunshots, kill it?

The negative x-y coordinates for player_image offset the point of rotation, so that it pivots around its centre. If you set those coordinates to (0, 0), the player image pivots on its top-left corner: [Screenshot from 2020-12-06 09-04-26] Left image: image(player_image, -50, -50, 100, 100) Right…

Maybe an additional tilemap-type layer – one that overlays your entire stage with tiles ranging between solid black and fully-transparent. These could include gradient ‘edge’ tiles.
