So, you need to design a path finding logic? I mean, if an enemy in another room hears you, but there are some sort of walls/doors between you. If so, perhaps you'll need to abstract the map into grids, or using some way points? I never successfully coded such thing, but I'm always curious how peopl...

I thought you were talking about 2.5D like those beat'em-up games. Instead of using ray every where, how about setup some tiles? I mean, the tiles don't have to be visible, they are used to cauculate the area where the enemy can here the target. For example, you can use some sort of simple flooding ...

Neither newFramebuffer in 0.7.2 nor newCanvas in 0.8.0 works.

It is my office PC so I'm not really panic. Actually it doesn't run those pixel effect demos (I only tried a few of them).
Although I think I should avoid canvas or pixel effect in my project unless I hit a situation that I must use them.

No, it doesn't work. ------ Edit* Video Card Vendor: Intel Renderer: Intel Bear Lake B OpenGL Version: 1.4.0 - Build 8.14.10.1930 GLU Version: 1.2.2.0 Microsoft Corporation Current pixel format: 6 Pixel Formats supported by this video card ------------------------------------------ # Type Flags Buf ...

With A = 1 - sA, this is equivalent to the "premultiplied" blend mode coming in LÖVE 0.8. The premultiplied blend equation is: R = srcR + (1 - srcA) * dstR There is no (easy) other way to set A to a custom value. Not exactly, the original equation (you may notice, I'm trying to port somet...

The fps changed between 150 and 160, occasionally it dropped to around 60, when I tested a minute ago. But sometimes the game lagged a lot (as I saw the the character 'jumped' a lot). I think it has something to do with my PC.

I need some special blend effects, but I'm not sure how to write. 1. Additive with alpha It works like this: R = MIN(dR + sR*A, 255) G = MIN(dG + sG*A, 255) B = MIN(dB + sB*A, 255) In which A is a custom alpha factor. 2. Color additive I don't know how to call this. Basically it uses additive blend ...
