exiting animation loop
Blitz3D Forums/Blitz3D Programming/exiting animation loop
| ||
| for example if you have an idle animation looping. when the conditions are met to end the loop( probably you pressed another key), the animation cycles until the end of the idle sequence how can you exit the loop instantly. the upshot of this is that if you are standing and idleing, when you walk off, the idle animation is still playing. look really crap |
| ||
| You could probably use AnimTime to find out when the animation is done. |
| ||
| I've never noticed the behavior you describe. Whenever I use the Animate command whatever animation is currently playing is cut-off immediately. Could you perhaps post code showing how you are playing the animation? |
| ||
| you could probably just increase the tween value and it will make a smooth transition regardless. |
| ||
| Huh? For a minute I was actually thinking that was his problem, that he had the optional tween value set really high and should therefore decrease or simply eliminate that value. I'm not sure how INCREASING the tween value would solve his problem. |
| ||
| increasing the tween value will make it worse. I have it so the idle plays when you are not pressing any keys. I included walk code so you can see what i am doing ;walking forward If KeyDown(200) And walkflag=False MoveEntity p\entity,0,0,.2 If Animating(p\model)=p\walk Animate p\model,3,.7,1 walkflag=True EndIf EndIf If Not KeyDown(200) Then walkflag= False ;Idle If Not Animating (p\model) If Animating(p\model)=p\idle Animate p\model,3,.2,2 ;this is the idle animation EndIf EndIf I tried idle with flags and still is does the same thing. idle loops, then plays the extra cycle when i break out of the loop by walking/jumping or whatever it only happens with idle . |

| Fredborg have you any examples of how to use this |
| ||
Something like this should show you how it would work.Graphics3D 640,480,0,2
SetBuffer BackBuffer()
camera=CreateCamera()
PositionEntity camera,0,20,-100 ; position camera so that robot will be in view when loaded
AmbientLight 132,132,132
light=CreateLight()
LightRange light,20
RotateEntity light,90,0,0
; Load anim mesh
robot = LoadAnimMesh("media\makbot\mak_running.3ds")
anim0 = 0
anim1 = LoadAnimSeq(robot,"media\makbot\mak_robotic.3ds")
Animate robot,1,1,anim1,10.0
While Not KeyDown(1)
TurnEntity robot,0,1,0
UpdateWorld
RenderWorld
If KeyHit(57) ; If space is hit
IWantToRun = True
End If
; Show which frame of total we are showing
Text 0,0,AnimTime(robot)+" of "+AnimLength(robot)
; If this is the last frame
If AnimTime(robot) => AnimLength(robot)-1
Text 0,10,"Animation Re-Started"
; Switch to running
If IWantToRun = True
Animate robot,1,1,anim0,10.0
IWantToRun = False
End If
End If
; If we should switch to running
If IWantToRun = True
Text 0,20,"I Want To Run, but I can't until this animation sequence is done!"
End If
Flip

| cheers fredborg, i will look through it when i have had some sleep. I have got to the stage where everyhting is working apart from this one damn glitch. bit frustrated now |
| ||
| Have you tried SetAnimTime(), try setting it to say 5 frames before the end of the previous animation. |
| ||
| I had thought about using set animtime(), but again I wasn't sure how to use it since there are no relevant examples included with The blitz docs, just brief descriptions. when you say set it to five frames etc ,how is that done why is n't just 'frames' rather than 'time' FYI, my idle sequence is from frame 31-45 suppose I have to use animtime() to find this out? |
| ||
| Sorry yes, it's Time not Frames. Try setting the anim time to 45, the end of your idle sequence, then immediately start the next anim. There will probably be a slight jump in the character though. We could do with some nice functions for more control over Blitzs animation. For example, the current Tween is just that, not a true Blend which would look much better. Tom |
| ||
| still no luck .whatever I do the frames just play out. tried this: If KeyDown(30) ; forward SetAnimTime p\model ,45,2;(2 is the idle sequence) If Animating(p\model)=p\walk Animate p\model,3,.7,1 EndIf MoveEntity p\entity,0,0,.3 EndIf I wonder of its because i have the controls set like this: If Animating(p\model)=p\walk Animate p\model,3,.7,1 EndIf normally to loop this sequence you would just have Animate p\model,1,.7,1 Unfortunately If keydown(30) Animate p\model,1,.7,1 Move entity p\entity,0,0,1 EndIf just makes the animation stick on the first frame key hit would be better, but then I wouldn't move forward unless I kept hitting the key In any case nothing seems to work. |
| ||
| good god I have done it. i will post the solution later tonight, not that its that interesting he he Its actually worked due to a little quirk in the way animation works ended up using setanimtime() cheers tom and fredborg , I learned quite bit today |
| ||
| I'm not sure what you did using SetAnimTime or why you are checking animation frames, but this is how I do it (assuming "idle" is sequence 2 and "walk" is 1): If KeyDown(30) If AnimSeq(p\model)<>1 Animate p\model,1,.5,1,.5 EndIf MoveEntity p\model,0,0,.3 Else If AnimSeq(p\model)<>2 Animate p\model,1,.5,2,.5 EndIf EndIf Basically I have nested If statements to check first if the key for walking is being held down. If so it then checks if the character is already in the walk animation; if not then start playing the walk animation. A similar check happens for the idle animation if the key is not being held down. Oh, and MoveEntity happens inside of the check for the key pressed down but outside the check if the walk animation is already playing. |
| ||
| cheers for that. i wll look in to it today. I have a tendency to make things more complicated than need be sometimes. I got my code working, but its created more problems now. |
| ||
| Heh, my laziness pays off a lot when I'm programming. I always seem to figure out ways to do things without writing lots of code. |
| ||
| yeah i jsut never thought of dong that: If AnimSeq(p\model)<>2 can't see the wood for trees sometimes |
| ||
| So, did my code work? You never mentioned and I just typed that from memory (ie. I haven't actually run it.) |
| ||
| just tested it and yup it worked. Thanks for that, saved me a lot of hassle |
| ||
| although there are still problems when for example if no keys are down you have have the idle as the default sequence just reinserting If AnimSeq(p\model)<>2 ;(depending on animation) Animate p\model,1,.5,2,.5 EndIf EndIf after every sequence dosn't work. |

| Ruz, I raped and pillaged the castle demo. Well, pillage anyway. Check near the middle. Does this help? Function UpdatePlayer( p.Player ) If KeyHit(56) ;fire? CreateBullet( p ) EndIf If KeyDown(203) ;left/right TurnEntity p\entity,0,6,0 ;turn player left/right Else If KeyDown(205) TurnEntity p\entity,0,-6,0 EndIf If KeyDown(30) ;forward If p\anim_speed<=0 p\anim_speed=1.75 Animate p\model,1,p\anim_speed EndIf MoveEntity p\entity,0,0,1 Else If KeyDown(44) ;back If p\anim_speed>=0 p\anim_speed=-1.75 Animate p\model,1,p\anim_speed EndIf MoveEntity p\entity,0,0,-1 Else If p\anim_speed ;stop animating p\anim_speed=0 Animate p\model,0 EndIf Goto skip ex#=EntityX(p\entity):ez#=EntityZ(p\entity) PositionEntity p\entity,ex,TerrainY( land,ex,0,ez )+1.5,ez Return .skip ty#=EntityY(p\entity) y_vel#=(ty-p\player_y) p\player_y=ty If KeyHit(57) ;jump? y_vel=5 ;2.4 Else y_vel=y_vel-.5 ;2 EndIf TranslateEntity p\entity,0,y_vel,0 End Function |
| ||
| unfortunately no dave because the castle demo does n't have an idle sequence,just 'stop animating' i believe I have almost got it cracked now(using mr hockings method). The only problem is that when i move forward and turn, the 'static turn' sequence plays which looks stupid. he should walk in this situation. same with move forward and jump. I tried something like if keydown (200) and keydown(203) then turnflag= false but it just doesn't work |
| ||
| update . everything works now apart from i can't work out how to disable running animation whilst jumping forward and running I want to have a simple jump animation for running jump as distinct from the animation for standing jump. here is the code so far suggestions greatly appreciated ;walking backward ################################ If AnimSeq(p\model)<>1 Animate p\model,1,.7,1 EndIf MoveEntity p\entity,0,0,.1;p\entity is the parent of p\model EndIf ;EndIf ;walking backward ################################ If KeyDown(208) If AnimSeq(p\model)<>1 Animate p\model,1,-.7,1,.5 EndIf MoveEntity p\entity,0,0,-.1 EndIf ;idle ##################################################################### If Not KeyDown(200) If Not KeyDown(203) If Not KeyDown(205) If Not KeyDown(208) If Not KeyHit(184) idleflag=True EndIf EndIf EndIf EndIf EndIf If idleflag=True If AnimSeq(p\model)<>2 Animate p\model,1,.2,2,7 EndIf EndIf ;idle ############################################################ ;turning#################################################### If KeyDown(203) If AnimSeq(p\model)<>4 Animate p\model,1,.05,4,5 EndIf TurnEntity p\entity,0,2,0 EndIf If KeyDown(205) If AnimSeq(p\model)<>5 Animate p\model,1,.05,5,5 EndIf TurnEntity p\entity,0,-2,0 EndIf ;jumping ############################################################ ty#=EntityY(p\entity);from castle demo y_vel#=(ty-p\player_y) p\player_y=ty If KeyDown(184) And EntityCollided(p\entity,TYPE_SCENERY>1 Animate p\model,3,.5,6 y_vel=1 Else y_vel=y_vel-.05 ;from castle demo EndIf |
| ||
| You're using lots of separate and/or nested If statements for checking key presses. I'd actually use one overarching If statement with lots of ElseIf for checking key presses. Pseudocode: If KeyDown(1) (handle walking) ElseIf KeyDown(2) (handle running) ElseIf KeyDown(3) (handle turning) Else (idle) EndIf |
| ||
| yeah i was trying to seperate them so it would be clearer to me.ok I will give it a try that way |
| ||
| well even thiough my code looks a bit 'newbyish' , it works now , so i am sticking with it. I have seperate animations for, walk,turn left, turn right, stilljump ,dying. When jumping and running at the same time the run animation plays which looks ok. when walking and turning the walk animation plays which again looks fine. I would like to add random idle sequences next but am not quite sure how to handle that. anyway thnks for the advice guys. |
| ||
| What jhocking suggests will not work if you add a keyhit() which triggers a one time animation (like an attack or shoot or throw or isdamaged animation), because the idle animation will automatically replace the one time animation if no key is held/hit during a loop. To prevent this you need to have another variable (like "AnimationState" (true or false)) which you set to true when a one time animation is triggered, and when you set to false when the one time animation is finished (to know this, check what is the current frame/pose using animtime()), and only allow a new movement/animation when the animationstate is false... |
