Help with whatdotcolor

[Vertico]

trying to make a pacman game, and i am stuck. im trying to get the oval 2 stop when it reaches the blue walls but when i try and do

code:

if whatdotcolor (x , y ) = blue then

it doesnt understand it and lets the oval go right throught the blue wall.
but if i put

code:

if whatdotcolor ( x, y ) not= black then

it works and stops when it hits the blue wall. this isnt good cuz i want 2 put in coins and warps but if it stops when its not black then that stuff isnt going to work.

can someone show me how 2 use this, or maby an easyer and faster way. thz.

Don't use whatdotcolour, and instead use a 2d array to store your map.

i dont understand what u mean by 2d array

Search the forums for a 2d array tutorial.

martin u sux... go whatdotcolour!! see you have to check the next step, you need to check if (x+1,y) or (x-1,y) or (x,y+1) or (x,y-1) is blue

andy can u give me the exact code for that. PLZ

[Andy]

sure... why dont i just do the whole freaking project for you while im at it? use ur brain, thats why you have one, if you cant, then too bad, drop compsci

heres what you have to do, you have to check if 1 pixel in front of your oval is blue, not the center of your oval, because it will obviously be blue.. so do somthing like this

code:

if whatdotcolor (x , y+radius ) = blue then %%if your heading up

I think you just took away andy's point.

[Martin]

Make sure you don't draw the pacman until AFTER you use the whatdotcolour.

i found out what i was doing wrong. the picture was "brightblue" instead of just blue. even thou they look almost the same.

no i didnt give him the exact code i just gave him an idea of what he had to do, if i were to give him all the code like the if statement for all 8 directions then that would be taking away andys point
