Re: Checking pixels in tmx files

Does the checking speed depend on the image color? I mean, would a seperate black and white collision mask speed up the process?

Re: Checking pixels in tmx files

Here it is.

Edit: I forgot to tell, but I made it with 0.8.0.

Re: Checking pixels in tmx files

The problem with pixel collision is that it is slow under most circumstances. Making the computer check thousands of pixels everytime is slow. Are you checking them every frame? If you are, just compare the pixels in an area close to the player (for example, pixels in a radius of 50 pixels around t...

Re: Checking pixels in tmx files

Pixel collision will be fine for me, but how can I make it faster if I plan on making huge levels?

Re: Checking pixels in tmx files

Ok, I will listen to you guys, pixel collision may be slow, but i don't know how to make any other collision system, except tile based. The one with polygons sounds good, but I have no idea how to implement it. Can somebody explain it, including the details?

Re: Checking pixels in tmx files

I know, but I want to experiment a bit with the different kinds of collision systems, starting with the easiest ones to implement. I have tried tile based so far, but I didn't like it, because it didn't give me enough freedom.

Checking pixels in tmx files

Hi. I am working on an engine for my later games and I'm using getPixel on a map image for collision detection, but have I realised that if my image would be larger, it would take more time to check for collisions. So I came up with the idea of checking pixels in tmx maps. Is that possible? If so, p...

getPixel in a line

Hi guys. I have bumped into a problem while making my own collision system. I know how to check for non-transparent pixels, but i have no idea how to check if there are any in a horizontal line. I have tried a for loop, but my character falls through the ground. Here is the function code: function m...
