Re: Burnt colors on Android
Hi Ats, I'm starting to get somewhere after doing this: vec3 LPosition = normalize(vec3(lightPosition[0][0], lightPosition[0][1], lightPosition[0][2])); I'd recommend normalizing your vector in a ZExpression before using it in your shader, that way you only do it once instead of for every pixel. <?x...

Re: Burnt colors on Android
Hi Ats, It's better, but the result still isn't the same on PC and Android. It's way more contrasted on Android for the ships, and the planets keeps burning, and I really don't know why... Make sure to normalize the light vector before doing any calculations with it ( instead of clamping the result ...

Re: Help with aiming from one vec3 to another
Hi Ats, I get why there is no roll, but I don't see where the negative atan2 yaw is coming from It depends on which axis of your line / model you want to point at the target. The calculations are just simple pythagorean theorem in 2D .. how to apply the results in 3D ( rotation ) is down to your set...

Re: Help with aiming from one vec3 to another
Hi Ats, Where do I mess up? It depends a little on your specific situation and the type of result you're after ... but let's say you want a floor-mounted turret to track a target then you only need pitch & yaw. Here's a example: <?xml version="1.0" encoding="iso-8859-1" ?> <Z...

Re: Velocity problem with "childrens"
Hi Ats, My problem is that with this little formula, the smoke velocity should regain the explosion velocity and continue it's way out of the screen with the little dot, but instead, it slows down to zero, and I don't understand why It's because when you spawn a clone that contains a array in its De...

Re: Cubemap?
Hej Ville, Someone on FL Studio forums asked how to use a cubemap in ZGE. I remember seeing this but when I search the ZGE forums I only find mentions of it but no project. Can't seem to find it either :P Maybe Kjell happen to have an example lying around? Depends a little on what this person means ...

Re: QOI
Hej Ville, What kind of compression ratio do you get for the included images? It varies from situation to situation, but in this case the original PNG images were 59228 bytes total, while the QOI images are only 36970 bytes. Due to the limited color palette & large number of masked pixels most o...

QOI
8) Attached is a QOI decoder including a simple demo that loads a external QOI image containing a single frame of the selected fighter into a texture. Obviously this makes more sense when the images you're loading are a lot bigger than in this example, but the approach would remain the exact same. h...

Re: Another simple question about basic trigonomety
Hi jinxtengu, I wanted to create a model that has 8 directions of animation depending on it's movements, so the most obvious comparison to what I want to implement would be the ghosts from a game like the arcade version of gauntlet. I understand the reference, but do keep in mind that Gauntlet doesn...

Re: Irregular sprite overlapping area
Hi rrTea, Is this possible to do in ZGE without using OpenGL calls? Sure. The only thing that is a little cumbersome is the fact that you can't access image data directly, so you need to copy the alpha channel of your image / spritesheet to a array ( using a BitmapExpression ) .. and if you want to ...

Re: AudioMixer resets when loading the project
Hi Ats, I'm using Chanel 2 and 3, but when I save the project, leave ZGE, and come back to it later, extra channels 2 and 3 are deactivated. Strange .. i just tried this to double-check and it works just fine for me. I can't set all manually at the start of the game either Also weird .. i initially ...

Re: Exporting images from ZGE
Hi Ats, Maybe it can be optimized, as I didn't know any another way to store the magical sentence as bytes at the end of the file. You could do something like this: <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplication Name="App" Caption="ZGameEditor applicati...

Re: Questions about ES2/GL3 shaders
Hi Ats, I tried to send the Y position of the model to the shader, using gl_Position.y -= modelPosition[0][1] , but it's not working. That doesn't work because you're transforming screen-space coordinates. You need to transform the vertices before applying the view & projection matrices. Is it p...

Re: Writing and Reading
Hi Zakk, I am trying a very simple exercise of placing a numerical figure in a txt file, say 10. Then I just need to get this file read and the number be displayed on screen. Since there's no way to write a string to a file i'd recommend using a byte array instead ( and do the string conversion your...

Re: How to use the ZGE-Light component?
