Hello for the ones that follow my posts a bit I'm making a tower defence and i'm doing very well i've almost finished all the algorithm

but I need to apply some texture to my rect and ellipses because right now it's pretty ugly

and I can't find what function I need to use to apply an img to a shape

do I need to use the fonction image and make it to appear at the same time as the ellipse so it will cover it and make like a texture but I find it a bit hard and bad so ^^

Thanks :)
