How to make it look 16 bit

[DunderOgge]

How do i make my sprites/background look like 16 bit. I dont know if its actually called that but i want it to look pixelated. Like undertale for example, where you actually can see the pixels. Cus when i wanna a background the pencil is round and i want it to be a square. Should i make objects and place them in the room instead?

You could use a filter to pixelize, such a shader is included in the tutorials - however, TYPICALLY, people actually draw their pictures pixelized before hand.

Also: No need to trend on Undertale, prior to this everyone was trying to make a FNaF game. Of course, Undertale is an RPG - something at the most basic levels is very easy to make, so no biggy - just throwing my 2 cents in.

The easiest way is to create your own sprites in that style. The size of the combat sprites used in undertale are around 120px by 200px, and are usually just a whit outline over a black background. An easy way to do this is to open up your original image and scale it to around the size mentioned above, then trace over parts with white and black until you're statisfied with the results.

As far as Making the overworld sprites, the easiest way that I found is to make your canvas 16px by 16px and using other existing 16 bit sprites as a guide for drawing your character. (Here's a handy link where you can download the sprite sheets that were used in undertale as a reference: http://www.spriters-resource.com/pc_computer/undertale/)

As others have mentioned... Make it 16 bit, make sprites that are 16 x 16 pixels. Easy to do. Funny thing is 8-bit is also 16 x 16 and I'd wager that Undertale is more 8-bit than 16. 8-bit also limits you to around 256 colors at any one time while 16 has a far greater color pallet. But hey with GameMaker, you do what you want to do without limitation.

Retro City Rampage and other games get by with even less pixels. Also to emulate that 16-bit feel make sure to keep the resolution low. It will also help performance.
