| How do you create a bullet and make it fly out of a gun? -me |
| ||
bullet = CreateCube() While EntityZ(bullet)<40 MoveEntity bullet,0,0,1 Wend |
| ||
| Lets start with something like a test area. Because you are new to 3D, you need to actually look at what is going on. Why not make a gun and a bullet. Show them on the screen and post back here. I will then show you how to fire the bullet from the gun. [edit]: the avarice of beaker fires sooth. |
| ||
First i would set up a type collection fro your bulletstype bullet field x,y,z field entity field speed field power end type something like that for a basic bullet. Everytime a bullet is fired, create a new type object, and copy the bullet mesh into the entity field. Set the bullet to the location of the gun and make sure it is rotated correctly. Then give the bullet a speed and power. Have a seperate function for cycling through all of your bullet objects: Updating their location, checking for collisions and such. Hope some of that helps :) |

| "patisawesome" This all seems to be for your "StormDimension" FPS project (Realistic Lighting/Acid/First Person Cam/Collision Detection/Gravity/FullScreen/Greate Models!) That's a complex project. How far have you got? |
| ||
| There's 137 rows not counting "End". -me |
| ||
| Other than the one you posted, have you got a working test area/level/environment and camera movement that you are happy with - ie. textured - different areas/stairs, etc? |
| ||
| I don't have any stairs yet, I also took off the door.(I'll add another one sometime). I've got the rest, not counting areas.(I'm not quite sure what you mean about "areas") -me |
| ||
| Is it a BSP level, a 3d model or have you just created it out of simple objects from within blitz? Is it textured with graphics? |
| ||
| You haven't replied - Have you seen Mark's BSP demo (the one with his "mario-like" character that you control in 3rd person in a QuakeIII level)? If you want I could strip it out and replace the third person camera and replace it with a normal first person one (so it plays quake-like) - this is a good level as it has various areas and stairs. |
| ||
| "patisawesome" - you are just bogging yourself down by trying to make it do everything a commercial FPS does, plus working on your own modeller too!!. Plus, you have a habit of submitting posts that are a bit brief as to what you want to do and also where the answer is sometimes a huge subject. At the moment, you are trying to add head-bobbing, gravity, bullets, AI, etc, all at the same time. |

| ||
| "patisawesome" I'm signing off now for time-difference reasons - it's getting on for 12:30am GMT. Mark's code was called "bspdemo" - search your hard drive "bspdemo*" to see if you have it. I'm not sure where it is currently located and you will need the textures. In the meantime, if anyone knows where Mark's BSP demo is currently located, can they let "patisawesome" know. I'm going to bed and won't be back here for probably 15+ hours. |
| ||
| One thing I would recommend is that you only process the first collision encountered on the bullets collision list. Usually there will only be one genuine collision anyway, and Blitz's collision system has a tendency to occasionally register extra collisions when two moving collision spheres/ellipsoids hit each other, so you might end up having your bullets applying extra hurt damage. |
| ||
| "patisawesome" Have a look at/play with some of the demos on your Blitz3d disk in your "Blitz 3D samples" folder: si\fps\fps.bb zenith\scare\scare.bb Misc\FPS\fps.bb Open DNA\Moving Targets\shooter.bb |
| ||
| I have. None of them help me. -me |
| ||
| why dont you just use the makehalflife2engine() function. It works perfactlt for me. :D |

| ||
| I don't use functions.:( -me |
| ||
| I don't use functions That's gonna put a serious dent in your programming, considering that 90% of Blitz's engine relies upon functions. I guess you're going to write your own? |
| ||
| Part of the reason is that I can't get them to work. -me |
| ||
Thin of a function this way. Its a peice of code that can be used anywhere without the need for you to type it again. All you have to do is make a call to it. In one of your games put all the code for moving an object inbetween thisfunction move() --(Put all code here) end function then in your main loop make a call to the function like this move() That way you have a function called move that gets called in the main loop of your program :) |
| ||
| How do I code a function that creates a bullet? -me |
| ||
| Seriously Pat, I think you really should start with something alot simplier, Like getting a camera to move around using the arrow key or something. I'm not being nasty, but the experience you pick up from doing small things like that, add to your understanding of things. They will give you an idea of how to do something similar and maybe more advanced. Don't jump in at the deep end :) |
