Room_width = 480
Room_height = 272
player1x = 15
player1y = 136
weapon=Image.load("weapon.PNG")
background=weapon
car1=Image.load("car1.PNG")
player1=car1

if pad:up() then
character=car1
player.y = player.y - 2
end

if pad:down() then
character = car1
player.y = player.y + 2
end

if pad:left() then
character = car1
player.x = player.x - 2
end

if pad:right() then
character = car1
player.x = player.x + 2
end

Give it a try now

as you may of noticed i added
pad = Controls.read()

I hope both of you realise that code won't display anything on the screen.

Room_width = 480
Room_height = 272
player1x =15
player1y =136
background =Image.load ("weapon.PNG")
player1=Image.load("car1.PNG")

function checkcontrols()
pad = Controls.read()
if pad:start() then
exitgame = 1
end
if pad:right() then
player1x = player1x +2
end
if pad:left() then
player1x = player1x -2
end
if pad:up() then
player1y = player1y - 2
end
if pad:down() then
player1y = player1y +2
end
end
function drawall()
screen:blit (0,0,background)
screen:blit(player1x,player1y,player1)
screen.waitVblankStart()
screen.flip()

end

while true do

checkcontrols()
drawall()
if exitgame ==1 then
break
end
end

Depends On what you want doing
