  1. Creating a hud/gui with GLSL

    Well, I mean how can I show it through the shader?
  2. Creating a hud/gui with GLSL

    ok I'll try and implement this, so I will have to rotate the vertices as the game is a first person shooter, so it rotates with the camera. Also, how can I create a dynamic text variable for the hud, such as the score?
  3. Hi, I am creating a game for my university project and now I am coming round to creating a hud, but I don't know how I should go about doing it with glsl. Can anyone help please?
  4. Maintaining speed with touch path

    Sorry I think I was a bit unclear about my intentions. My plane has a velX and velY value that is added to the position to move it. When a path is created I'm having an issue moving the plane along to the next point. I tried : double theta = Math.atan2(pathPoints.firstElement().y-posY, pathPoints.firstElement().x - posX); velX=(float) (magnitude * Math.sin(theta)); velY=(float) (magnitude * Math.cos(theta)); but this results in the plane moving in a straight line away from the point, in the opposite direction. I also tried doing posY-velY but this resulted in the plane flying in a circle. What am I doing wrong?
  5. Maintaining speed with touch path

    Forgot to mention, if the plane is moved after being held down, points are collected and added to this vector.
  6. I'm currently making a game similar to the airport controller games already available but I'm having a bit of difficulty keeping the same speed with a path. When the plane is initialised, it is given a velX and velY value that changes the position of the plane, but when the user touches the plane, a vector of points is created that set the position of the plane. My question is, how can I keep the plane moving at the same speed as it was set, instead of just moving from point to point at whatever speed the path is created?
  7. AABB transforming

    I managed to work out what was wrong after creating a box and printing results to the screen. Basically, each time the render function was being called the transformation matrix was multiplying each corner over and over, making the boxes move further away constantly. I fixed it by setting a start minimum and maximum and setting these first when updating. Thanks for the advice!
  8. AABB transforming

    Hi I've managed to implement a bounding box using Assimp and opengl by finding the smallest and highest x,y,z position, and these are shown correctly. However, I have attempted to update the boxes by finding all corners and multiplying it by the object's transformation matrix, and then finding the minimum and maximum x, y, z values of these corners. But when I try this I get really small values that are too small to be detected for collisions. I have checked the multiplication of the vector and the matrix but everything seems okay, is there something I'm missing?
  9. Ray collision help?

    Hi I tried to implement the AABB bounding box, but when I apply the model's transformation matrix the values are incorrect. I think this is something to do with the rotation in th matrix. After debugging i found a lot of the values were low numbers. To apply the transformations I set each corner of the box and applied the transformation to each one, then circled between them to find the lowest value.
  10. Ray collision help?

    Thanks for the information! I will attempt to implement this, I figured as much with the frame buffer.
  11. Ray collision help?

    Hi I'm creating a game using OpenGL and c++ for my final year project and I've got a quick question about using rays for collisions. I understand the theory behind it but I'm having an issue implementing it. I'm loading my models using Assimp and I'm trying to create a bounding box around the models so that I can check for a ray-box intersection, but when the transformations are applied during rendering, the box does not move with the model. I have created my own vertex and fragment shaders that draws the models. What approach is best for situation? Should I find a way to also move the bounding box, or is there another method to help with this? I considered using a frame buffer object from the point of view of the ray but I think this is overcomplicating things. I'm using rays as the game is a first person sniping game, and bullets would move too fast to find the box intersections.
  12. Transform feedback particle problem

    No I developed it on my AMD card on my home computer, but the tutorial I followed used NVidia I believe, I'll have to research into AMD specific code and see what I'm doing wrong.
  13. Hi, I've created a program that creates a particle system and it works perfectly on the computers at university, but when I run the program at home, the particles do not draw. Does anyone know the issue? If it helps, my graphics card is an ATI Radeon HD 5450, thanks.
