| I'm trying to make my cam move up and down while I walk, I can't get it to! I've even tried AddAnimSeq. Can anybody help? -me |
| ||
| if the camera is parented to a player pivot: if walking then a=a+1 mod 360 positionentity camera, entityx(camera,0), entityy(player,0)+.5*sin(a), entityz(camera,0),0 |
| ||
| It doesn't work the way I want it to. -me |
| ||
| If you expect someone to offer help then you need to *EXPLAIN* HOW IT DOESN'T WORK, OR WHAT EXACTLY IS NOT WORKING CORRECTLY. Simply saying it doesn't work doesn't tell us anything. (We cannot read your mind...) |
| ||
| I mean that it's acting the way it was before!(In other words, it woundn't move up and down) -me |
| ||
| Well, "If walking" is pseudocode, of course. You must think with the code, not only copy and paste. so when your player is walking because of some keypresses or whatever, then set a variable named "walking" to 1, else to 0. To simplyfy this, just omit the IF statement. Also enlarge the Y-multiplyer to 2.0. a=a+1 mod 360 positionentity camera, entityx(camera,0), entityy(player,0)+2.0*sin(a), entityz(camera,0),0 Also - you need a pivot named player that is parent of the camera to work with this ( player=createpivot(): camera=createcamera(player) ) Walking around will then no longer mean you have to move the camera, instead move the player-pivot, which will carry the camera automaticly. To turn around the player you will have to turn the player-pivot, while to look up or down you'll have to turn the camera. |
| ||
| It still doesn't work. -me |
| ||
| Post your code otherwise we'll be here until eternity ^^ |
| ||
| Here is some of it: If KeyDown(200) MoveEntity cam,0,0,0.1 EndIf If KeyDown(203) TurnEntity cam,0,3,0 EndIf If KeyDown(205) TurnEntity cam,0,-3,0 EndIf If KeyDown(208) MoveEntity cam,0,0,-0.2 EndIf |

| "patisawesome" This all seems to be for your "StormDimension" FPS project (Realistic Lighting/Acid/First Person Cam/Collision Detection/Gravity/FullScreen/Greate Models!). Your code suggests you are not using "mouse-look" (you are turning the camera with the keys) - refer to your "Firing" post. |
| ||
| I am turning with the keys. The reason why is that it won't turn when I move the mouse. -me |
| ||
| I changed my code so that the cam swivels around when the mouse moves. -me |
| ||
| you could also try using the less powerfull makequake2() function. That again works perfactly for me :D |
| ||
| Whats MakeQuake2? -me |
| ||
| It's not documented. Try my world creator or else! (It's the link below. It writes Blitz code for you!) Doggie This reply is an advertisement for HomeSpun GOLD(A) |
| ||
| It doesn't tell how much it costs.(Or is it free?) -me |
| ||
| Just click on the picture of it and find out! Doggie |
| ||
| Mmmm, it seems that you have really read much about the blitz commands or looked through any of the samples. There are many ways you could make the camera bob up and down. 1. Try the MakeQuake2 Function, as mentioned above (although i think it's over-rated ;) ) 2. Use the moveentity command to move the camera up until it reaches a certain height, then move it down till it reaches a certain height, then repeat. 3. You could make use of the sin command, to make the camera move in a wave like fashion. |
| ||
| None of it will work. -me |
| ||
yes it will:positionentity cam,0,sin(millisecs())*5,0 the camera moves up and down |
| ||
| It doesnt work. None of it. Any of it. Why doesnt it work? |
| ||
| It works, but it's too jerky. -me |
| ||
| Then modify it so that it does work. patisawesome, you really need to try harder. Trial and Error, it's called. You have to do it yourself, because with what little information you provide the rest of us here on the forum, we just can't help you. Don't you see that they are mocking you? Try the MakeQuake2 Function, as mentioned above (although i think it's over-rated ;) ) It's not documented. It doesnt work. None of it. Any of it. Why doesnt it work? Either you have to be MUCH more descriptive on what your problem is or you will just have to do it yourself. That's reality. If you want help, then take the time to write here the problem IN DETAIL. |
| ||
| Hey Pat. How old are you anyways? Serious question. I'd like to help you, but as WolRon says, you aren't giving good descriptions of your problems you have in many posts i've seen. I'm not getting on at you man, but you should try a little hardre. You'll learn alot more too :) Can you show us any code you have so far for making the camera move up and down? |
| ||
Here is the code I have so far for walking up and down:If KeyDown(200) MoveEntity cam,0,0,0.1 PositionEntity cam,EntityX(cam),Sin(MilliSecs()*100/time,EntityZ(cam) EndIf -me |

Hey, it's uncommented and done quickly and works. Change the variables bob_speed and bob_height to adjust the bobbing :)Graphics3D 800,600 SetBuffer BackBuffer() camera=CreateCamera() PositionEntity camera,0,1,0 light=CreateLight() tex=CreateTexture(64,64,1+8) SetBuffer TextureBuffer(tex) For loop=0 To 1000 Color Int(Rnd(20,255)),Int(Rnd(20,255)),Int(Rnd(20,255)) Rect Int(Rnd(0,62)),Int(Rnd(0,62)),2,2 Next SetBuffer BackBuffer() Dim cube(100) For loop=0 To 100 cube(loop)=CreateCube() PositionEntity cube(loop),Rnd(-11,11),-0.5,Rnd(-100,200) Next plane=CreatePlane() EntityTexture plane,tex bob_angle=0 bob_height=100 bob_speed=8 y_pos=1 While Not KeyHit(1) If KeyDown(200) Then bob_angle=bob_angle+bob_speed:If bob_angle>359 Then bob_angle=0 MoveEntity camera,0,Sin(bob_angle)/bob_height,0.1 End If UpdateWorld RenderWorld Flip Wend End |

| Ain't you supposed to be able to rotate, and move into another direction? Cause that's the hard part of it, especially if you don't know sinus and cosinus. (You doknow about then, right patisawesome? Please say you do.) |
| ||
| Wouldn't say that it was particulary hard. Pat hasn't exactly been 100% clear about what he's after :) |
| ||
| I don't know about them eBusiness. -me edit I also still cannot get it to bob up and down. I even modified around with my code! |
| ||
| Well, Sin and Cos are basically mathimatically waves. If you input an angle into sin, it will return a ratio between the x and y. You can use this waves to create smooth motions, like the bobbing one. |
| ||
| I'm getting better results... -me |
| ||
| Keep at it :) Good way to learn :D |
| ||
| One of Filaxs' demos had some good camera-bob code! :) Ask him if he'd share it? Although you may want to tone it down a bit, when I tried his demo it made me dizzy :) |
