Hi everyone! I know something about coding (very basics stuff) and I'm new to PICO-8.
I'm doing some tests, one of this consist in highlighting an object when the user switch between two objects.
I need some kind of switch, like: when you press 4 the first time highlight X, the second time Y, the following times switch to the other.
This is the code, sorry for bad english:
rect1_x1=5 rect1_y1=120
rect1_x2=20 rect1_y2=110
rect2_x1=5 rect2_y1=5
rect2_x2=20 rect2_y2=15
sex1=-1 sey1=-1
sex2=-1 sey2=-1
function _init()
cls()
end
function _update()
cls()
if btn(4) then
sex1=rect2_x1-1
sey1=rect2_y1-1
sex2=rect2_x2+1
sey2=rect2_y2+1
elseif btn(4) then
sex1=rect1_x1-1
sey1=rect1_y1-1
sex2=rect1_x2+1
sey2=rect1_y2+1
else end
end
function _draw()
--background-----------
rectfill(0,0,127,127,1)
--select---------------
rectfill(sex1,sey1,
sex2,sey2,10)
--1--------------------
rectfill(rect1_x1,rect1_y1,
rect1_x2,rect1_y2,8)
--2--------------------
rectfill(rect2_x1,rect2_y1,
rect2_x2,rect2_y2,8)
end

You need to separate drawing and updating game state (and a game state to start with!)
Something like:
— game state local switch_state=true function _update() — note: using btnp to avoid auto-repeat if btnp(4) then switch_state=not switch_state end end function _draw() if switch_state then — draw for X else — draw rect for Y end end |
