help animating player in corona sdk
- by andrew McCutchan
working on a game in the corona sdk with lua and I need help so the player animates on the line drawn. Right now he animates at the beggining and the end but not on the line.
here is the player code
function spawnPlayerObject(xPlayerSpawn,yPlayerSpawn,richTurn) --spawns Rich where we need him.
-- riches sprite sheet and all his inital spirites. We need to adjust this so that animations 3-6 are the only ones that animate when moving horizontally
local richPlayer = sprite.newSpriteSet(richSheet1,1,6)
sprite.add(richPlayer, "rich", 1,6,500,1)
rich = sprite.newSprite(richPlayer)
rich.x = xPlayerSpawn
rich.y = yPlayerSpawn
rich:scale(_W*0.0009, _W*0.0009) -- scale is used to adjust the size of the object.
richDir = richTurn
rich.rotation = richDir
rich:prepare("rich")
rich:play()
physics.addBody( rich, "static", { friction=1, radius = 15 } ) -- needs a better physics body for collision detection.
end
and here is the code for the line
function movePlayerOnLine(event)
--for the original image replace all rich with player.
if posCount ~= linePart then
richDir = math.atan2(ractgangle_hit[posCount].y-rich.y,ractgangle_hit[posCount].x-rich.x)*180/math.pi
playerSpeed = 5
rich.x = rich.x + math.cos(richDir*math.pi/180)*playerSpeed
rich.y = rich.y + math.sin(richDir*math.pi/180)*playerSpeed
if rich.x < ractgangle_hit[posCount].x+playerSpeed*10 and rich.x > ractgangle_hit[posCount].x-playerSpeed*10 then
if rich.y < ractgangle_hit[posCount].y+playerSpeed*10 and rich.y > ractgangle_hit[posCount].y-playerSpeed*10 then
posCount = posCount + 1
end
end
I don't think anything has changed recently but I have been getting an error when testing of " attempt to upvalue "rich" a nil value" on the second line, richDir = etc.
