So many questions !

Ok so for 1.

void main()
{
LoadScene("scenes/scene.esc");
}

// Receives a vector and an angle value in radians and returns the rotated vector
vector2 rotate(const vector2 &in p, const float angleRad)
{
return vector2(
p.x * cos(angleRad) + p.y * sin(angleRad),
- p.x * sin(angleRad) + p.y * cos(angleRad));
}

// Controls the player
void ETHCallback_player(ETHEntity@ thisEntity)
{
ETHInput@ input = GetInputHandle();

// computes the distance our player must move in order to keep
// a speed of 60 pixels per second
float speed = UnitsPerSecond(120.0f);
float angleSpeed = UnitsPerSecond(160.0f);

vector2 direction(0.0f,-1.0f);

if (input.KeyDown(K_RIGHT))
{
thisEntity.AddToAngle(-angleSpeed);
}

if (input.KeyDown(K_LEFT))
{
thisEntity.AddToAngle(angleSpeed);
}

// compute rotation vector and do movement
direction = rotate(direction, degreeToRadian(thisEntity.GetAngle()));

if (input.KeyDown(K_UP))
{
thisEntity.AddToPositionXY(direction * speed);
}

if (input.KeyDown(K_DOWN))
{
thisEntity.AddToPositionXY(direction *-speed);
}
}

2.The XML tags are in the *.ent files you need Sublime Text or notepad+ to read them they are UTF16 Encoded, there is a basic triangle example inside.

3.I don't quite understand your question, are they invisible because thats the way you want them, or because their Z-order is messed up? If you want them invisible you can iterate through them at run time and just make them invisible till you want them to be visible. If that isn't the case check your z-orders in the editor they are probably being drawn behind your background. Also make sure the background is a 'horizontal' entity and walls, players, etc.. are 'vertical' entities.

Let me know if that helped or if I missed something.

As for the triangle I personally have 0 knowledge as I have never needed it. Give me till tomorrow I will play with the XML tags and see if I can figure out how it works.

Ok just so I don't have a brain fart here, you have a image where the walls/obstacles are already drawn on the image itself? If that is correct, then you want to create invisible collision masks, so the single image has collision characteristics? I hope that is what you meant. If so just use primitives to draw out where the walls are, leaving them visible while creating your scene, then at your 'onSceneCreated' function just hide them all.
thisEntity.Hide(true);

4: float myTimer = GetTime();
Then just do your figuring for the difference between when you reset your timer to how much time has passed on the computer and make your timer.

Hello Mr. Administrator,

1. I am using thisEntity.Hide(true); and it works great! Thank you for letting me know about this command. It is perfect for hiding invisible walls so a player cannot walk through the walls shown on the environment map.

You asked, "you have a image where the walls/obstacles are already drawn on the image itself? Correct?"

Answer: Yes, that is correct. The background environment map contains all the walls, obstacles, background, objects, etc. That is why I need an invisible wall solution. thisEntity.Hide is perfect for this!


2. I am now using float myTimer = GetTime(); to create a timer. It works pretty well. Thank you for letting me know about this command.

3. I am learning new things about the Ethanon Engine everyday. It is really an amazing tool and I am having a great time working with it. My biggest challenge coming up soon is to implement A* path finding for the game enemies. I have never done this before so I picked up a book on the subject called, "Programming Game AI By Example". It is a great book on basic game AI, but it is written in C/C++. The discussion of AI concepts is very helpful though. I did some searches for Angel Script A* path finding scripts, but couldn't find anything. Let me know if you have any ideas on where to find A* path finding using Angle script code.

Thank you,

OK so for the polygon shapes, the values are relative to the size you have set for the collision box. So 1.0 = 100% positive values are the right values for X and the bottom values for y. So adversely the negative values are the left values of X and top values of Y. All between the scale of -1.0 to 1.0

Good luck!

So basically, I think this is what your after, this gives you 0-360, you should be able to point your character at that.

void main()
{
LoadScene("scenes/newScene.esc", "NewGame", "MainLoop");

// Prefer setting window properties in the app.enml file
SetWindowProperties("Ethanon Engine", 1024, 768, true, true, PF32BIT);
}

void NewGame()
{
SetGravity(vector2(0,0));
}

void MainLoop()
{
ETHInput @input = GetInputHandle();
if (input.KeyDown(K_ESC))
{
Exit();
}

const float fpsRate = GetFPSRate();
DrawText(vector2(0,0), "FPS: " + fpsRate, "Verdana20_shadow.fnt", ARGB(250,255,0,0));
}

void ETHCallback_Player(ETHEntity@ thisEntity)
{
ETHInput @input = GetInputHandle();
vector2 mousePos = input.GetCursorPos();
vector2 charPos2D = thisEntity.GetPositionXY();
vector2 screenSpaceCharPos = charPos2D - GetCameraPos();

const float charCursorRadAngle = getAngle(normalize(screenSpaceCharPos - mousePos));
const float charCursorDegreeAngle = radianToDegree(charCursorRadAngle);
thisEntity.SetAngle(charCursorDegreeAngle); //add in a delay if you dont want it instant

DrawText(vector2(50,50), "Current Radian: " + charCursorRadAngle, "Verdana20_shadow.fnt", ARGB(250,255,0,0));
DrawText(vector2(50,80), "Current Degree: " + charCursorDegreeAngle, "Verdana20_shadow.fnt", ARGB(250,255,0,0));
}

Keep it powers of 2, and yeah the same size. I will have an example maybe tomorrow of the bullet angle, I just have to read up on something, I am sure I know it off hand but it has been awhile.
